  • bash output is inserted into the clipboard, then mousepad is started and the clipboard content is pasted. xsel and xdotool needs to be installed. Instead of the mousepad any other editor can be used. I've successfully tested the Sublime Text Editor and it opens a new tab for each new paste. Check Sample output for a usage example. This command is originated from here - http://goo.gl/0q9UT4 Show Sample Output

  • This command is suitable to use as application launching command for a desktop shortcut. It checks if the application is already running by pgrepping its process ID, and offer user to kill the old process before starting a new one. It is useful for a few x11 application that, if re-run, is more likely a mistake. In my example, x2vnc is an x11 app that does not quit when its connection is broken, and would not work well when a second process establish a second connection after the first broken one. The LC_ALL=C for xmesseng is necessary for OpenSUSE systems to avoid a bug. If you don't find needing it, remove the "env LC_ALL=C" part

    sh -c 'if pgrep x2vnc && env LC_ALL=C xmessage -button "Kill it:0,Ignore it:1" "Another connection is already running. Should I kill it instead of ignoring it?"; then killall x2vnc; fi; x2vnc -passwd /home/Ariel/.vnc/passwd -east emerson:0'
