display text file within an editor on whatever workspace is in front of you

env DISPLAY=:0 /usr/bin/gedit ~/df.txt && wmctl -a gedit
Usage example: display output of a command running in the background at desired time The example in details: report disk quotas and that backup process will start soon In my /etc/crontab file I added following four lines for weekly automatic incremental backup: . 52 13 * * 7 root mount /dev/sda3 /media/da2dc69c-92cc-4249-b2c3-9b00847e7106 . 53 13 * * 7 knoppix5 df -h >~/df.txt . 54 13 * * 7 knoppix5 env DISPLAY=:0 /usr/bin/gedit ~/df.txt && wmctl -a gedit . 55 13 * * 7 root /home/knoppix5/rdiff-backup.sh . line one: as root mount media for backup on Sunday 13:52 line two: as user knoppix5 write out to text file in home directory the free space of all mounted disks on Sunday 13:53 line three: in front of you open and display a very simple text editor (I prefer gedit) with content of previously reported disk usage at Sunday 13:54 wmctl -a gedit means (from the manual): -a Switch to the desktop containing the window , raise the window, and give it focus. line four: as root run incremental backup script rdiff-backup.sh as root on Sunday 13:54 . my rdiff-backup.sh, with root permissions backups in short time (writes only changes from the last backup) the etire linux system (except excluded - i.e. you don't want backup recursively your backup disk), looks like this (Show sample output):
