Unix – Delete files older than a certain number of days using find command

Delete files older than 30 days

1	find . -mtime +30 -exec rm {} \;

1. Save the deleted files to a log file

1	find /home/a -mtime +5 -exec ls -l {} \; > mylogfile.log

This way, you'll get a line at top with the date the line is executed (also a line at the bottom).
The last two semicolons are necessary, one is for find and one for bash.

2. modified

Find and delete files modified in the last 30 minutes

1	find /tmp/ -type f -mmin 30 -exec rm {} \;

mtime = days
mmin = minutes

3. force

force delete temp files older then 30 days

1	find /tmp -mtime +30 -exec rm -f {} \;

4. move the files

move files older than 30 days to an archive folder – and preserve path strcuture

1	find /tmp -mtime +30 -exec mv -t {} /archive/directory/ \;

mv -t: ensure directory structure is preserved
