Hi onenessboy,
You can start by showing us the complete, exact output produced by the command:
Code:
df -P /backup

If the output from the above command doesn't complain about an unknown -P option, the percentage of space used on the filesystem containing /backup should be in field #5 on line #2 of the output from the above command.

If it does complain about an unknown -P option, show us the complete, exact output from the command:
Code:
df /backup

so we can figure out which field and line we need to examine to determine if you have reached your goal.

Hi RudiC,
Why not:
Code:
ls -r1 2[0-9][0-9][0-9][01][0-9][0-3][0-9]_[0-2][0-9][0-5][0-9].tar.gz | awk -F_ 'T[$1]++ {print "echo rm " $0}'  | sh

Because that will remove old files from the most recent date first. And onenessboy wants to remove old backup files from the oldest date first. And he wants to add code to exit the script when the capacity on that filesystem drops below 60% after each date change when one or more backup files were removed for any given date.
