Fast experiment to use cron to open a terminal window and execute a command. Success!
The crontab item is:
* * * * * DISPLAY=:0.0 /usr/bin/xfce4-terminal -x top # * * * * * - the crontab time codes. Substitute your own. # DISPLAY=:0.0 - sends the subsequent commands to the screen # /usr/bin/xfce4-terminal - the application (opens a terminal window) # -x top - execute the top command in the applicationOnce a minute, a new terminal window spawns running 'top', just as intended.
