#description: dmenu for killall
|

#usage: dmenu-killall is best suited for launching from a shortcut

#example: dmenu-killall
|
|
#a gui menu appears asking for which app to kill
|
|
|

#variables are impractical to save complex cmds because of shell expantion

#therefore functions are required: http://mywiki.wooledge.org/BashFAQ/050
