autoclean vs autoremove vs clean

-    clean: clean clears out the local repository of retrieved package files. It removes everything but the lock file from /var/cache/apt/archives/ and /var/cache/apt/archives/partial/. When APT is used as a dselect(1) method, clean is run automatically. Those who do not use dselect will likely want to run apt-get clean from time to time to free up disk space.

-    autoclean: Like clean, autoclean clears out the local repository of retrieved package files. The difference is that it only removes package files that can no longer be downloaded, and are largely useless. This allows a cache to be maintained over a long period without it growing out of control. The configuration option APT::Clean-Installed will prevent installed packages from being erased if it is set to off.

Autostart

Add an autostart application for all users

  1.     Create a .desktop file in the /etc/xdg/autostart/ directory:
        [Desktop Entry]
        Type=Application
        Name=Files
        Exec=nautilus -n
        OnlyShowIn=GNOME;
        AutostartCondition=GSettings org.gnome.desktop.background show-desktop-icons
  2.     Replace Files with the name of the application.
  3.     Replace nautilus -n with the command you wish to use to run the application.
  4.     You can use the AutostartCondition key to check for a value of a GSettings key.
    The session manager runs the application automatically if the key's value is true. If the key's value changes in the running session, the session manager starts or stops the application, depending on what the previous value for the key was.

ex. /etc/xdg/autostart/blueman.desktop

Add an autostart application for a user

~user/.config/autostart/

But unfortunately none of those met my requirements

8 Most Awesome Quick File Searching Tools for Linux Desktop

اضافه کردن به برنامه‌ها

Make a .desktop file in ~/.local/share/applications/ for your application with a text editor. If done right, this will cause an entry in the main menu, and supply the needed information to the system to run it.

File name looks like:

.desktop [ex: leafpad.desktop]


Example: (replace <...> with appropriate content)

Code:

[Desktop Entry]
Type=Application
Icon=
Name=
Comment=
Categories=


Exec=
Path=
StartupNotify=true
Terminal=false

There are numerous possible keys. All the specifications are here to study:

http://standards.freedesktop.org/des...est/index.html

More .desktop files to see are in /usr/share/applications, but those are for all users.

Grep

Although grep command is not a tool for directly searching files (its instead used to print lines matching a pattern from one or more files), you can employ it to locate files. Assuming you know a phrase in the file(s) you are looking for or you are looking for a file that contains a particular string of characters, grep can help you list all files that contain a particular phrase.
For example, if you are looking for a README.md file which contains the phrase “An assortment”, which you suspect should be somewhere in your home directory, possibly in ~/bin, you can locate it as shown.
$ grep -Ri ~/bin -e "An assortment"
OR
$ grep -Ri ~/bin/ -e "An assortment" | cut -d: -f1

How to Autorun application at the start up in Linux

Purpose
This article describes how to automatically start an application during or after boot of a Colibri module running Embedded Linux.
Daemons
You can easily start your scripts or applications as daemons.
A daemon is an application that runs as a "background" process (without a terminal or user interface).
Systemd
Starting with V2.x of our Linux BSP we use systemd as our init and service manager.
systemd is a system and service manager for Linux, also capable of replacing the traditional SysV init system.
http://www.freedesktop.org/wiki/Software/systemd/
http://www.freedesktop.org/software/systemd/man/systemd.html
A unit configuration file whose name ends in .service encodes information about a process controlled and supervised by systemd.
Service files can be found in /etc/systemd/system/ and, for distribution provided ones in /lib/systemd/system/. Services can be started or permanently enabled using the systemctl command.
The common configuration items are configured in the generic "[Unit]" and "[Install]" sections. The service specific configuration options are configured in the "[Service]" section.
Service files must include a "[Service]" section, which carries information about the service and the process it supervises.
For more information on options of [Service] section refer to: http://www.freedesktop.org/software/systemd/man/systemd.service.html#Options
Procedure
Create a unit configuration file ending in .service
Copy the unit configuration file to "/etc/systemd/system" and use the systemctl tool for starting or permanently enabling the service.
Using the systemctl command
From: http://www.freedesktop.org/software/systemd/man/systemctl.html
Reload the systemd configuration and unit files:
root@colibri-t20:~# systemctl --system daemon-reload
Check status, start and stop a service, valid until next reboot:
root@colibri-t20:~# systemctl status .service
root@colibri-t20:~# systemctl start .service
root@colibri-t20:~# systemctl stop .service
Add a service to or remove it from the ones started at boot. Note that this neither starts or stops the service but takes only effect during the next boot:
root@colibri-t20:~# systemctl enable .service
root@colibri-t20:~# systemctl disable .service
Example unit configuration file to automatically execute the (hypothetical) mydatalogger application at start up:
[Unit]
Description=mydatalogger service, collects and logs data in the background
After=multi-user.target
 [Service]
Type=simple
ExecStart=/usr/bin/mydatalogger
 [Install]
WantedBy=multi-user.target
 Shells
/etc/profile
Each time a login shell is spawned the script /etc/profile plus all scripts in /etc/profile.d are executed. This is done for logins over a serial line, over an ssh connection and also for logins in the display manager to a graphical desktop.
/etc/profile is sourced upon login: it sets up the environment upon login and application-specific settings by sourcing any readable file in /etc/profile.d/.
Using /etc/profile is well suited to set the environment or to do some small tasks. Note that these scripts must return control in order to continue with the login.
Remove the file /etc/profile.d or the additions to /etc/profile in order to undo the automatic execution.
    Procedure
Add a script file in /etc/profile.d/*.sh.
Example script file:
#!/bin/sh
#script file for deleting backup entries
rm /home/root/*~
Graphical
You can start applications automatically when you login into your Window Manager or Desktop Environment.
The lxsession session manager can start applications when the graphical environment is started. This can be achieved in two ways:
- A lxsession specific way in which the entries in the files /etc/xdg/lxsession/LXDE/autostart and in ~/.config/lxsession/LXDE/autostart are parsed.
- A generic way which many session managers support. Files in the folders /etc/xdg/autostart/ and ~/.config/autostart/ ending in .desktop get parsed and if applicable the application described therein is started.
http://wiki.lxde.org/en/LXSession
LXSession Autostart file
Edit /etc/xdg/lxsession/LXDE/autostart or ~/.config/lxsession/LXDE/autostart. Add the application to a new line in the file. If you want that your application gets restarted should it get terminated abnormally, precede the application name with a @.
e.g at @lxterminal to /etc/xdg/lxsession/LXDE/autostart
@lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
@xscreensaver -no-splash
@lxterminal
Note that this file is not a shell script and therefore shell acrobatics like redirectors and pipes are not allowed. If required this can be worked around by spawning a custom shell script which in turn can support the full shell feature set.
.desktop files
Creating a .desktop file.
Adding the .desktop file to autostart.
http://standards.freedesktop.org/desktop-entry-spec/latest/
Note that in /usr/share/applications/ a number of .desktop files already exists which can be copied into the autostart folder
For Example:
If you want to execute lxterminal automatically at startup.
Create a terminal.desktop in /etc/xdg/autostart/ .
Add some keys like:
    [Desktop Entry]. (Must be the first line of every desktop file and is the section header to identify the block of key value pairs associated with the desktop. Necessary for the desktop to recognize the file correctly.)
    Name of the application.(The name of the Desktop Entry group - should be unique on the system )
    Type of the application. (Possible values are "Application", "Link" or "Directory".)
    Exec filename of the application plus optionally arguments.
    Terminal (Describes whether the application should run in a terminal.)
File content with the entries should be as follows:
[Desktop Entry]
Name=LXTerminal
Type=Application
Exec=lxterminal
Terminal=false
Save the .desktop file.
Note: A graphical file manager will list .desktop files not with their file name but rather with the value of the key "Name". e.g. in the example above "LXTerminal".
To disable the automatic start of an application, just either remove the respective .desktop file from /etc/xdg/autostart/ and/or .config/autostart/ or add the key NotShowIn=LXDE; to the desktop file. Alternatively use the graphical front end 'LXDE Menu'/Preferences/'Desktop Session Settings' and untick the 'Enabled' checkbox.

How install and run application in linux

1. Unpack the archive.
2. To build catfish run
      ./configure
      make
3. To install catfish run either
      (sudo) make install
   or
      (sudo) checkinstall
4. For a list of command line options run
      catfish --help
5. To create a distributable package of catfish run
      make deb

if we have file with extension .sh:

# sh namefile.sh

before name file "sh"

Eject / safely remove vs umount

Eject USB drives / eject command

The best way to unplug a USB external hard-drive, after proper unmounting, is:
udisksctl power-off -b /dev/sdb
or
udisks --detach /dev/sdb

udisks --detach /dev/sdX

So is not the same unmount, eject and detach
udisks = power off the usb
umount = just unmount the partition not the whole pendrive
eject = the same or very close to umount command

eject(1): eject removable media - Linux man page

command line - Eject / safely remove vs umount - Unix & Linux Stack Exchange

Night Mode

How to Change Display Brightness Using Command Line in Linux – Linux Hint
How to change LCD brightness from command line (or via script)? - Ask Ubuntu

Screen identification:

xrandr -q
or
xrandr -q | grep " connected"

Description:

1000 — Lowest value (super warm/red) - 1.00000000, 0.18172716, 0.00000000, }, /* 1000K */
4000 — Default night light on temperature
5500 — Balanced night light temperature
6500 — Default night light off temperature
10000 — Highest value (super cool/blue)
The three columns above are values for Red, Green and Blue.

Daily mode:

xrandr --output LVDS-1 --gamma 1:1:1 --brightness 1

Night Mode:

xrandr --output DP-1-1 --gamma 1.1:0.8:0.7 --brightness 0.5
xrandr --output LVDS-1 --gamma 1.1:0.8:0.7 --brightness 0.5
xrandr --output LVDS-1 --brightness 0.5

Change Xfce Theme from bash script:

xfconf-query -c xsettings -p /Net/ThemeName -s "Adwaita-dark"

Redshift:

redshift -O 2600
redshift -l 55.7:12.6 -t 5700:3600 -g 0.8 -m vidmode -v
Disable
redshift -O 6500
or
Use redshift -x to reset everything:
-x Reset mode (remove adjustment from screen).
DESCRIPTION
A configuration file with the name `redshift.conf' can optionally be placed in
`~/.config/'. The file has standard INI format. General program options are placed under
the `redshift' header, while options for location providers and adjustment methods are
placed under a header with the name of that provider or method. General options are:
temp-day = integer
Daytime temperature
temp-night = integer
Night temperature
transition = 0 or 1
Disable or enable transitions
brightness-day = 0.1-1.0
Screen brightness at daytime
brightness-night = 0.1-1.0
Screen brightness at night
gamma = R:G:B
Gamma adjustment to apply
adjustment-method = name
Select adjustment method. Options for the adjustment method can be given under the
configuration file heading of the same name.
location-provider = name
Select location provider. Options for the location provider can be given under the
configuration file heading of the same name.
Options for location providers and adjustment methods can be found in the help output of
the providers and methods.
EXAMPLE
Example for Copenhagen, Denmark:
$ redshift -l 55.7:12.6 -t 5700:3600 -g 0.8 -m vidmode -v
An example configuration file with the same effect as the above command line:
[redshift]
temp-day=5700
temp-night=3600
gamma=0.8
adjustment-method=vidmode
location-provider=manual
redshift.conf - configuration file for redshift and gtk-redshift
[redshift]
; Set the day and night screen temperatures
temp-day=5800
temp-night=4800
; Enable/Disable a smooth transition between day and night
; 0 will cause a direct change from day to night screen temperature.
; 1 will gradually increase or decrease the screen temperature
transition=1
; Set the screen brightness. Default is 1.0
;brightness=0.9
; It is also possible to use different settings for day and night since version 1.8.
;brightness-day=0.7
;brightness-night=0.4
; Set the screen gamma (for all colors, or each color channel individually)
gamma=0.9
;gamma=0.8:0.7:0.8
; Set the location-provider: 'geoclue', 'gnome-clock', 'manual'
; type 'redshift -l list' to see possible values
; The location provider settings are in a different section.
location-provider=manual
; Set the adjustment-method: 'randr', 'vidmode'
; type 'redshift -m list' to see all possible values
; 'randr' is the preferred method, 'vidmode' is an older API
; but works in some cases when 'randr' does not.
; The adjustment method settings are in a different section.
adjustment-method=randr
; Configuration of the location-provider:
; type 'redshift -l PROVIDER:help' to see the settings
; e.g. 'redshift -l manual:help'
[manual]
lat=43
lon=1
; Configuration of the adjustment-method
; type 'redshift -m METHOD:help' to see the settings
; ex: 'redshift -m randr:help'
; In this example, randr is configured to adjust screen 1.
; Note that the numbering starts from 0, so this is actually the second screen.
[randr]
screen=0

How to configure Samba in Debian

[SOLVED] Thunar Shares Plugin - Linux Mint Forums

Samba/ServerSimple - Debian Wiki

sudo apt install samba
mkdir /home//sambashare/
sudo nano /etc/samba/smb.conf

[sambashare]
    comment = Samba on Ubuntu
    path = /home/username/sambashare
    read only = no
   browsable = yes

sudo service smbd restart
sudo smbpasswd -a username
\ip-addresssambashare

Samba GUI page

One of the most asked for features for Samba is a graphical user interface to help with configuration and management. This is finally starting to happen.
In fact, there are now several GUI interfaces to Samba available. Some of them are listed below and I will add the others as soon as I can find the URLs.
Smb4K - An SMB share browser for KDE
Smb4K is an SMB share browser for KDE. Its features are inspired by Komba2 by Frank Schwanz. It uses the Samba software suite for an easy access to the SMB shares of your local network neighborhood.
LDAP Account Manager
LDAP Account Manager (lam) is a webfrontend for managing accounts stored in an OpenLDAP directory. It supports Samba 3/4 users, groups and hosts.
Webmin
Webmin is a general web based unix administration tool with a Samba component. Have a look at the Webmin pages.
SMB2WWW
This SMB2WWW is an extension to smbclient, so you can use it directly as a CGI-binary. You can get more information at http://www.scintilla .utwente.nl/users/frank/smb2www/.
smb-mode.el - Emacs mode
smb-mode.el is an Emacs mode for editing smb.conf.
gnomba - A GNOME SMB Subnet Scanner
Gnomba is a GUI machine and share browser for the SMB protocol. Gnomba allows you to scan any number of subnets for machines with SMB. The workgroups, machines and share are shown in a tree-view. For each machine you can then view the list of shares, and mount, unmount or browse them.
jags - Yet Another GNOME SMB Client
Jags is a Gtk+ based "windows network neighbourhood browser". The program parses the output from smbclient and use this to display a graphic view of the network. This program does the parsing with help from shell- scripts.
komba2 - A KDE SMB Subnet Scanner
Komba2 is a GUI machine and share browser for the SMB protocol. Komba2 allows you to scan any number of subnets for machines with SMB. The workgroups, machines and share are shown in a tree-view. For each machine you can then view the list of shares, and mount, unmount or browse them. You can also search a machine by name or ip.
konqueror - KDE File Browser
KDE's filebrowser Konqueror can access smb filesystems using smb:// URL's.
KSambaPlugins
KSambaPlugin is a KDE 3 plugin for configuring a SAMBA server. It consists of two plugins, a KControl Center module for all SAMBA options and a Konqueror properties dialog plugin for quickly configuring the SAMBA share options of a directory.
ChangePassword
This is a web-based tool that allows users to change their unix,samba and squid password using a web-based interface. Freely available here.
smbc - Simple Samba Commander
Simple Samba Commander is a text mode SMB network commander. With SMBC, you can browse your local network or use the search function to find files in a share. You can also download/upload files and directories or create them both locally and remotely. SMBC features the resume capability and UTF-8 encoding support.
SMB Web Client
SMB Web Client is a single PHP script to access Windows Networks similar to Windows Network Environment. It requires smbclient, PHP 4.1.x+, and a web server.
Davenport WebDAV-SMB Gateway
Davenport is a servlet that makes it possible to access samba-shares via webdav through a servlet-container. It allows access to samba-shares through a firewall/proxy without the need to open the smb-related ports and without a VPN-client. See http://davenport.sourceforge.net/ for more info.
QtSmbstatus
QtSmbstatus is a GUI for smbstatus. It is meant to provide the possibility of administering remote machines. QtSmbstatus was designed as a client/server system (with SSL). Possibilities include: view connections, disconnect a user, or send a message (with smbclient -M). For more info see, http://qtsmbstatus.free.fr/.
LDAP Admin
Ldap Admin is a free Win32 application for managing LDAP directories. This tool lets you browse, search, modify, create and delete objects on an LDAP server.
SMBNetFS
SMBNetFS is a Linux filesystem that allows you to use Samba/Microsoft network in the same manner as the network neighborhood in Microsoft Windows. The program uses fuse() and libsmbclient. Currently SMBNetFs work on Linux 2.4/2.6, but should work also on FreeBSD 6.0.
IntegraTUM WebDisk
IntegraTUM WebDisk is a free web application which gives you direct access to a file server. It is written using Java Servlets and the jCIFS library. Supported file servers are Samba, MS Windows and NetApp OnTAP and those based on the CIFS-protocol.
SambaDAV
SambaDAV is an SMB-to-WebDAV bridge, written in PHP and running as a web application on Linux servers. It acts as the glue between Windows Samba/CIFS filesharing and WebDAV internet file access.

Compress PDF

sudo apt install ghostscript

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/prepress -dNOPAUSE -dQUIET -dBATCH -sOutputFile=compressed_PDF_file.pdf 00.pdf

The good ghostscript:
gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=merged.pdf mine1.pdf mine2.pdf
or even this way for an improved version for low resolution PDFs (thanks to Adriano for pointing this out):
gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -sOutputFile=merged.pdf mine1.pdf mine2.pdf
In both cases the ouput resolution is much higher and better than this way using convert:

sudo apt install imagemagick
convert -density 300x300 -quality 100 mine1.pdf mine2.pdf merged.pdf

I found a superb trick to shrink the size of PDFs, I reduced with it one PDF of 300 MB to just 15 MB with an acceptable resolution!

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/default -dNOPAUSE -dQUIET -dBATCH -dDetectDuplicateImages -dCompressFonts=true -r150 -sOutputFile=output.pdf input.pdf

sudo apt install pdftk

Pixelated (lossy):
convert input.pdf -compress Zip output.pdf

SQLite Database Recovery

-dPDFSETTINGS=configuration
Presets the "distiller parameters" to one of four predefined settings:
/screen selects low-resolution output similar to the Acrobat Distiller "Screen Optimized" setting.
/ebook selects medium-resolution output similar to the Acrobat Distiller "eBook" setting.
/printer selects output similar to the Acrobat Distiller "Print Optimized" setting.
/prepress selects output similar to Acrobat Distiller "Prepress Optimized" setting.
/default selects output intended to be useful across a wide variety of uses, possibly at the expense of a larger output file.

----------------

PDF optimization level selection options:
-dPDFSETTINGS=/screen (screen-view-only quality, 72 dpi images)
-dPDFSETTINGS=/ebook (low quality, 150 dpi images)
-dPDFSETTINGS=/printer (high quality, 300 dpi images)
-dPDFSETTINGS=/prepress (high quality, color preserving, 300 dpi imgs)
-dPDFSETTINGS=/default (almost identical to /screen)

How to enable complete dark mode in LibreOffice
As I mentioned earlier, you need to enable a system-wide dark mode first. This will ensure that the window color (or the title bar) blends well with the in-app dark color.
Next, open any LibreOffice tool from the suite such as Writer. Then from the menu, click Tools -> Options -> Application Colors and select Document background & Application background as Black or Automatic (whichever works for you).
Libreoffice Application Colours
In case the icons are not in dark colour, you can change them from menu (as shown in the image below), Tools -> Options -> View and my personal choice on MX Linux, is the Yaru icon style from Ubuntu (if you have a dark version of the icon pack, select that).
Libreoffice Iconstyle
Of course, you can also try some other icon themes available for Linux distros.
The end result should look like this:
3 Libreoffice Dark
Additional tip for LibreOffice flatpak package
If you’re using the Flatpak package of LibreOffice suite, the header area (or the menu area) of LibreOffice may look white. In that case, you can try navigating to Tools-> Options-> Personalization and then select the “Grey theme” as shown in the screenshot below.

Back Up The XFCE4

How To Back Up The XFCE4 Desktop Settings On Linux

PATH

The PATH is an important concept when working on the command line. It's a list of directories that tell your operating system where to look for programs, so that you can just write script instead of /home/me/bin/script or C:UsersMeinscript. But different operating systems have different ways to add a new directory to it:
Windows
The first step depends which version of Windows you're using:

If you're using Windows 8 or 10, press the Windows key, then search for and select "System (Control Panel)".
If you're using Windows 7, right click the "Computer" icon on the desktop and click "Properties".

Click "Advanced system settings".
Click "Environment Variables".
Under "System Variables", find the PATH variable, select it, and click "Edit". If there is no PATH variable, click "New".
Add your directory to the beginning of the variable value followed by ; (a semicolon). For example, if the value was C:WindowsSystem32, change it to C:UsersMein;C:WindowsSystem32.
Click "OK".
Restart your terminal.

Mac OS X
Open the .bash_profile file in your home directory (for example, /Users/your-user-name/.bash_profile) in a text editor.
Add export PATH="your-dir:$PATH" to the last line of the file, where your-dir is the directory you want to add.
Save the .bash_profile file.
Restart your terminal.

Linux
Open the .bashrc file in your home directory (for example, /home/your-user-name/.bashrc) in a text editor.
Add export PATH="your-dir:$PATH" to the last line of the file, where your-dir is the directory you want to add.
Save the .bashrc file.
Restart your terminal.

Unless you consider running chkdsk.exe under wine or virtualisation, Linux cannot run it. There is a linux compatible tool that can be used to fix ntfs partitions that is called ntfsfix and is available on most distribution repositories.
It is NOT chkdsk for Linux and may not produce results compatible with Microsoft Windows, however it is able to fix some common ntfs possible problems. It may lose your data while attempting repairs, even though chkdsk may do that too. Example usage:
ntfsfix /dev/sdxY
Where you should replace xY with the appropriate letters for the partition you want to fix.

Yes. This was handled by fsck on some releases. If the partition is not listed in /etc/fstab, then you will likely need to tell it the partition type. I've used this from a Linux CD to recover a partition Windows wouldn't boot from.
Based on the comments below, the actual fixing is done by the ntfsfix program. It should be available, even if there is no program to run a fsck on and NTFS file system.

 

ntfsfix /dev/sdxx
This command comes from ntfsprogs.
Do be warned (from the man page):
ntfsfix is a utility that fixes some common NTFS problems. ntfsfix is NOT a Linux version of chkdsk. It only repairs some fundamental NTFS inconsistencies, resets the NTFS journal file and schedules an NTFS consistency check for the first boot into Windows.

In my case, none of fsck & ntfsfix could fix the issue of my external NTFS mobile disk.
I end up to boot into windows os, and use follow steps to fix the disk issue.
Steps:
Check the identifier of the bad disk. e.g g
Open the "cmd" terminal of windows.
Input chkdsk : /f to fix it.
Where is the identifier, e.g chkdsk d: /f
Then it would be fixed within seconds (For a disk of size 1Tb).
After years, finally I found something that windows can do easily, but linux can't ;)

عدم استفاده از تمام ظرفیت سی پی یو

ps -A -o pcpu | tail -n+2 | paste -sd+ | your command

Explanation:

ps: In most Unix and Unix-like operating systems, the ps program displays the currently-running processes
tail: display the tail end of a text file or piped data
paste: It is used to join files horizontally (parallel merging) by outputting lines consisting of lines from each file specified, separated by tab as delimiter, to the standard output. When no file is specified, or put dash (“-“) instead of file name, paste reads from standard input and gives output as it is until a interrupt command [Ctrl-c] is given.

Qemu-kvm

Qemu: QEmu is a complete and standalone software of its own. You use it to emulate machines, it is very flexible and portable. Mainly it works by a special 'recompiler' that transforms binary code written for a given processor into another one (say, to run MIPS code on a PPC mac, or ARM in an x86 PC).
To emulate more than just the processor, Qemu includes a long list of peripheral emulators: disk, network, VGA, PCI, USB, serial/parallel ports, etc.
KQemu: In the specific case where both source and target are the same architecture (like the common case of x86 on x86), it still has to parse the code to remove any 'privileged instructions' and replace them with context switches. To make it as efficient as possible on x86 Linux, there's a kernel module called KQemu that handles this.
Being a kernel module, KQemu is able to execute most code unchanged, replacing only the lowest-level ring0-only instructions. In that case, userspace Qemu still allocates all the RAM for the emulated machine, and loads the code. The difference is that instead of recompiling the code, it calls KQemu to scan/patch/execute it. All the peripheral hardware emulation is done in Qemu. This is a lot faster than plain Qemu because most code is unchanged, but still has to transform ring0 code (most of the code in the VM's kernel), so performance still suffers.
KVM: KVM is a couple of things: first it is a Linux kernel module—now included in mainline—that switches the processor into a new 'guest' state. The guest state has its own set of ring states, but privileged ring0 instructions fall back to the hypervisor code. Since it is a new processor mode of execution, the code doesn't have to be modified in any way.
Apart from the processor state switching, the kernel module also handles a few low-level parts of the emulation like the MMU registers (used to handle VM) and some parts of the PCI emulated hardware.
Second, KVM is a fork of the Qemu executable. Both teams work actively to keep differences at a minimum, and there are advances in reducing it. Eventually, the goal is that Qemu should work anywhere, and if a KVM kernel module is available, it could be automatically used. But for the foreseeable future, the Qemu team focuses on hardware emulation and portability, while KVM folks focus on the kernel module (sometimes moving small parts of the emulation there, if it improves performance), and interfacing with the rest of the userspace code.
The kvm-qemu executable works like normal Qemu: allocates RAM, loads the code, and instead of recompiling it, or calling KQemu, it spawns a thread (this is important). The thread calls the KVM kernel module to switch to guest mode and proceeds to execute the VM code. On a privileged instruction, it switches back to the KVM kernel module, which, if necessary, signals the Qemu thread to handle most of the hardware emulation.
One of the nice things of this architecture is that the guest code is emulated in a posix thread which you can manage with normal Linux tools. If you want a VM with 2 or 4 cores, kvm-qemu creates 2 or 4 threads, each of them calls the KVM kernel module to start executing. The concurrency—if you have enough real cores—or scheduling—if not—is managed by the normal Linux scheduler, keeping code small and surprises limited.

Virtualbox

sudo apt install virtualbox-guest-utils virtualbox-guest-dkms
sudo apt install build-essential dkms

Debian -- Package Search Results -- virtualbox

sudo apt install virtualbox-guest-utils virtualbox-guest-dkms
Then execute again sudo ./VBoxLinuxAdditions.run

To check the version of the Linux kernel run the command: $ uname -r OR $ hostnamectl | grep -i kernel

---------------

sudo apt install build-essential dkms
sudo apt-get install virtualbox-guest-additions-iso
---------------
Here are the manual steps to install VirtualBox Guest Additions kernel modules inside the VM:
Download the ISO file, e.g.
wget http://download.virtualbox.org/virtualbox/5.0.20/VBoxGuestAdditions_5.0.20.iso -P /tmp
Mount the ISO file:
sudo mount -o loop /tmp/VBoxGuestAdditions_5.0.20.iso /mnt
Run installer (add -x after sh to debug):
sudo sh /mnt/VBoxLinuxAdditions.run
---------------

In case we have installed the OSE edition of Virtual Box from the repositories we can add the guest additions from the repositories in the guest.

sudo apt-get install virtualbox-guest-additions-iso
/usr/share/virtualbox/VBoxGuestAdditions.iso

--------------
sudo apt install virtualbox-guest-dkms virtualbox-guest-x11 virtualbox-guest-utils
sudo apt-get install make gcc
