Catfish

catfish --fileman=nautilus --path=/ --hidden --method=locate
sudo geany /usr/lib/python3/dist-packages/catfish/CatfishWindow.py

Find

• Find from root path:
  $ find / -name "index.html"
$ find /  -name '*.mkv'
• Find from current path:
  $ find . -name "index.html"
• For search in text
$ grep -r 'text' /

Locate

/etc/fstab
for edit config in locate This file:
/etc/updatedb.conf
for update indexing this file:
# updatedb

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

Console

history: Command History #rm ~/.bash_history or # history -c

awk '!x[$0]++' ~/.bash_history > te.txt
cat .bash_history nl|sort -k 2|uniq -f 1|sort -n|cut -f 2 > te.txt
history > te.txt

history -n reads all lines from $HISTFILE that may have occurred in a different terminal since the last carriage return
history -w writes the updated buffer to $HISTFILE
history -c wipes the buffer so no duplication occurs
history -r re-reads the $HISTFILE, appending to the now blank buffer

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

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

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.

To black list a module or driver you don't have to use a command "blacklist".
Open this file (Create it if it does not exist):
sudo nano /etc/modprobe.d/blacklist.conf
add a line like this:
blacklist nouveau
save the file, reboot the system. You can use modprobe -r nouveau to remove it temporary.

Best Image Viewers for Linux
Note: You should be able to find these image viewers listed in your software center or AppCenter. If you don’t find it there, we’ve mentioned the instructions for manual installation as well.
1. Nomacs
What’s good about it?
Simple & Fast UI
Image adjustment tools (color & size)
Geolocation of the image
Metadata information panel
LAN Synchronization
Fullscreen mode
A free and open source image viewer that does not come baked with any fancy features. However, Nomacs does support most of the common image file formats if you want to use it.
The user interface is very simple but it does offer some essential features for image adjustment (color, brightness, resize, crop, & cut). In addition to that, it also supports fullscreen mode, histogram, and a lot of different panels that you can toggle for metadata, edit history, and more such information.
How do I install it?
You can find it listed in the software center/AppCenter for easy installation. If you want to install it via terminal, you can take a look at their GitHub page or type in the command below:
sudo apt install nomacs
2. Eye Of Gnome
What’s good about it?
A dead simple image viewer
Slideshow style (if that’s what you like)
An image viewer tailored for GNOME desktop environment
This is a classic image viewer developed as a part of The GNOME Project a lot of years ago. Do note that this isn’t actively maintained anymore. But, it still works on Ubuntu’s latest LTS release and several other Linux distros.
If you want a dead simple image viewer where you browse through the images in a slideshow-type UI and get the meta info in the sidebar, Eye of GNOME should be your choice. One of the best for GNOME desktop environment!
How do I install it?
To manually install it on Ubuntu (or Ubuntu-based Linux distros) type in the following command:
sudo apt install eog
For other distros and source, you should follow the GitHub page.
3. Eye Of MATE Image Viewer
What’s good about it?
A simple image viewer
Plugins supported
An image viewer tailored for MATE desktop environment
Yet another simple image viewer with the basic functionalities of slideshow view and rotating images.
Even if doesn’t support any image manipulation feature, it does support numerous image file formats and can handle big image files.
How do I install it?
For Ubuntu/Ubuntu-based distros, type in the following command:
sudo apt install eom
If you need help for other distros and the source, follow their GitHub page.
4. Geeqie
What’s good about it?
A flexible image manager that supports plugins (you’ll find other image viewers supported as well)
Information about the color profile
Geeqie is an impressive image manager and viewer. It supports other image viewers as plugins but does not offer any image manipulation tools.
If you need to know the color profile, image info, and manage/view a collection of images. It should be a good choice for that.
How do I install it?
Type in the terminal:
sudo apt install geeqie
For the source, you can refer the GitHub page.
5. gThumb Image Viewer
What’s good about it?
An all-in-one image viewer with the ability to manage, edit and view the images
Reset EXIF orientation
Convert image formats

How to enable complete dark mode in LibreOffice

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.

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:\Users\Me\bin\script. 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:\Windows\System32, change it to C:\Users\Me\bin;C:\Windows\System32.
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.

Before I started working on Flocate I took a look at all the existing solutions I found (MATE Search Tool (formerly GNOME Search Tool), Recoll, Krusader (locate based search), SpaceFM File Search, Nautilus, ANGRYsearch, Catfish, ...) to find out whether it makes sense to improve those, instead of building a completely new application. 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:

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