# mklauncher -n "Global launchers" -e "xdg-open '/usr/share/applications'" -i "mk-folder.png" -cat "System" -k "Global;Launcher;"

"xdg-open" Open a folder using the default file manager. This option requires that the "xdg-utils" package be installed.


Open folder directly :

# mklauncher -n "Global launchers" -e "nautilus /usr/share/applications" -i "mk-folder.png" -cat "System" -k "Global;Launcher;"

# mklauncher -n "Global launchers" -e "dolphin /usr/share/applications" -i "mk-folder.png" -cat "System" -k "Global;Launcher;"

# mklauncher -n "Global launchers" -e "thunar /usr/share/applications" -i "mk-folder.png" -cat "System" -k "Global;Launcher;"

Files

Open file by means of "xdg-utils" package :

# mklauncher -n "Debian GNU Linux" -e "xdg-open '/opt/books/Debian manual.pdf'" -i "mk-PDF.png" -cat "Education" -k "Linux;manual;"

"xdg-open" Open a file using the application appropriate for the file type. This option requires that the "xdg-utils" package be installed.


Open PDF file directly :

# mklauncher -n "Debian GNU Linux" -e "evince '/opt/books/Debian manual.pdf'" -i "mk-PDF.png" -cat "Education" -k "Linux;manual;"

# mklauncher -n "Debian GNU Linux" -e "atril '/opt/books/Debian manual.pdf'" -i "mk-PDF.png" -cat "Education" -k "Linux;manual;"


Create a simple symbolic link, on the desktop :

# mklauncher -link "/opt/books/Debian manual.pdf"

URL

Open website by means of "xdg-utils" package :

# mklauncher -n "GNU Linux OS" -e "xdg-open https://www.linux.org" -i "mk-internet.png" -cat "Network"


Using the option "-url" :

# mklauncher -n "GNU Linux OS" -url "https://www.linux.org" -i "mk-internet.png" -cat "Network"

Some desktops only allow launchers of websites created with the "-url" option in the Desktop folder.


Open web site directly :

# mklauncher -n "GNU Linux OS" -e "firefox https://www.linux.org" -i "mk-internet.png" -cat "Network"

Launch how root


NORMAL

Run by means of terminal :

# mklauncher -n "Gedit(root)" -e "su -c 'gedit'" -i "mk-text.png" -terminal -cat "Utility" -k "Gedit;root;"


Run by means of "gksu" :

# mklauncher -n "Gedit(root)" -e "gksu gedit" -i "mk-text.png" -cat "Utility" -k "Gedit;root;"

This option requires that the "gksu" package be installed.


WAYLAND and administrative privileges

To create a launcher that runs applications with administrative privileges, you need to use "xhost" (server access control program for X), and a script as follows :

1)Create a "sh" script, with the following name :

    "Application name" + "_wayland.sh"

Example :

    synaptic_wayland.sh

The content of this script should be :

#!/bin/sh
#
xhost +si:localuser:root
gksu synaptic
xhost -si:localuser:root
#

2)Grant execution permissions to the script :

$ su -l
# chmod +x synaptic_wayland.sh

3)Copy the script to a standard location, example :

# cp synaptic_wayland.sh /usr/local/bin

4)Create a launcher with "mklauncher" :

# mklauncher -n "Synaptic package manager" -e "synaptic_wayland.sh" -i "mk-package.png" -cat "System" -k "Synaptic;package;manager;"

This option requires that the "gksu" package be installed.

Remove launcher

# mklauncher -r "Firefox web browser"


Remove launcher for current user only :

# mklauncher -u -r "Firefox web browser"


- NOTE -

The "-r" option can only erase launchers that were previously created with "mklauncher". To erase launchers that were not created with "mklauncher", it is necessary to write the real name of the file ".desktop". You can use the file manager to copy and paste the names of the ".desktop" files.

# mklauncher -r 'start_smb'


Remove launcher for current user only :

# mklauncher -u -r 'start_smb'


It is also possible to eliminate the launchers directly :

# rm '/usr/share/applications/start_smb.desktop'

# rm '/home/[Current user]/.local/share/applications/start_smb.desktop'

Fix desktop

If is not possible to detect the path of the desktop, use "-fix-desktop" to correct this problem. Example :

# mklauncher -fix-desktop "/home/[user]/darbastalis"

# mklauncher -fix-desktop "/home/[user]/Scriptorio"

# mklauncher -fix-desktop "/home/[user]/Namizje"

    -mime "text-editor:c-editor:c++-editor:"

    -mime "php-editor:image/png;image/jpeg;"

To view the details of a specific combination, execute "mklauncher" with the name of the desired type combination, such as :

# mklauncher -mime "web-browser:"
# mklauncher -mime "text-editor:"

To see all the type combinations in detail, run the command :

# mklauncher -mime "predefined-list"

To create a text file, run the command :

# mklauncher -mime "predefined-list" > "predefined-list.txt"

The text file "predefined-list.txt" contains detailed information on each combination of mime types.

How to create an ".png" icon

To create a custom icon, you must follow the following procedure :

1)Take a screenshot that contains the desired image.

2)Open the captured image with an image editor, for example "Gimp".

3)Copy an area of 256x256 px, and save how a new "Namefile.png" file.

4)Use the "iconrb" command to create a new file with rounded edges :

    $ iconrb "Namefile.png"
   
    rb-Namefile.png

5)Place this file in an accessible location, example :

    /opt/icons/rb-Namefile.png

6)Use the new PNG icon to create a launcher :

    # mklauncher -n "My app" -e "my_app" -i "/opt/icons/rb-Namefile.png"
