Remove Old Files

The find command can be used to supply a list of files to the rm command or the "-delete" command can be used directly.

find /backup/logs/ -name daily_backup* -mtime +21 -exec rm -f {} ;

find /backup/logs/daily_backup* -mtime +5 -exec rm -f {} \;

find /backup/logs/daily_backup* -mtime +5 -delete;
