Will stop all running containers, then remove all containers

**This isn't for selectively handling containers, it removes everything**

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):

find /PATHNAME -type l | while read nullsymlink ; do wrongpath=$(readlink "$nullsymlink") ; right=$(echo "$wrongpath" | sed s'|OLD_STRING|NEW_STRING|') ; ln -fs "$right" "$nullsymlink" ; done

After you run this script, you can check status for broken symlink with this command:

find -L . -type l

fold -sw 20 <(echo "Long Text to be wrapped with \"\n\"") |sed ':a;N;$!ba;s/ *\n/\\n/g'

I used this fragment with Imagemagick convert so that I can place long text strings in pictures. The "\n" gets converted to a true newline in the image.

So this fragment uses fold command to wrap the line and then sed to convert newlines (and any trailing spaces on the line) to the text "\n"

find -name pom.xml | while read f; do cd $(dirname "$f"); mvn clean; cd -; done;

this command is used to locate all pom.xml files, access the dir and do a mvn clean, but I do recommend you to disable network interfaces to not download dependencies packages to be faster.
