Desktop shortcut to command in terminal

[farhan]

Hi,

I want to ask if it is possible to create Desktop shortcut for command that needs to be run in terminal.

For Example what i want to do is that If i press Alt+Ctrl+5 then it runs the following command in terminal without opening the terminal.

echo 4 | sudo tee /sys/class/backlight/acpi_video0/brightness

yes you can do this pretty easily

Step one - Make your command a shell script, its pretty easy.

open kate and paste in

#!/bin/bash
echo 4 | sudo tee /sys/class/backlight/acpi_video0/brightness

of course you can add any command (or commands ) the shell will take

and save it as <fileName>.sh

then we need to make it executable

so find your new script in dolphin then rt.click and select "Properties" and then in the dialog switch to the Permissions tab and check "is executable".

then you need to make an entry in your menu for this item

1 .right click your "K" menu and select "Edit Applications"
2. Select the sub folder for your new item then Click New Item it will then prompt for a name for this new item
3. edit the command to <full path to script> (for example if your script is in your home folder and your user name is bob the command is /home/bob/script.sh)
4. under the advanced tab toward the bottom you will see current shortcut key press the button next to is and then your key (or combo)
5. save your changes to the menu

now try your command to be sure it works. if it does not work ; first try the kmenu you made to be sure that your command is correct then check to see if your shortcut is enabled in system settings -> keyboard shortcuts -> custom shortcuts under KmenuHelper.

For short one liners like that you don't even need the script just:

1 .right click your "K" menu and select "Edit Applications"
2. Select the sub folder for your new item then Click New Item it will then prompt for a name for this new item
3. edit the command to `echo 4 | sudo tee /sys/class/backlight/acpi_video0/brightness`
4. under the advanced tab toward the bottom you will see current shortcut key press the button next to is and then your key (or combo)
5. save your changes to the menu

now try your command to be sure it works. if it does not work ; first try the kmenu you made to be sure that your command is correct then check to see if your shortcut is enabled in system settings -> keyboard shortcuts -> custom shortcuts under KmenuHelper.

However, this requires root, and sudo has no terminal to ask you for a password on. It would be better to use kdesudo as that will give you a graphical prompt for your password.

But there is probably a more elegant command... do your brightness up/down keys work? can you change the brightness in system settings? If so then you can use this dbus call instead:

qdbus org.kde.Solid.PowerManagement /org/kde/Solid/PowerManagement org.kde.Solid.PowerManagement.setBrightness $BRIGHTNESS

Where $BRIGHTNESS is a number from 1 to 100. This has the advantage of it not requiring root privileges to do so you do not need to enter your password every time.
