Periodically deleting old files



  • I spotted this cron job on a dev server.

    00 20 1 * * /usr/bin/find . -type f -mtime +30 -exec rm -f {} \;
    

    It's meant to remove files older than 30 days once a month in a particular directory. Problem is that it runs as root. Now there are no files in /root/

    root@foo:~# ls -l ~
    total 10
    drwxr-xr-x  2 root root    6 2013-09-01 20:00 libxml/
    drwxr-xr-x  2 root root    6 2013-09-01 20:00 libxslt/
    drwxrwxrwx  6 1107 1107   53 2013-09-01 20:00 postgresql-8.4.13/
    drwxr-xr-x 19 inet 1000 4096 2013-09-01 20:00 unixODBC-2.3.1/
    drwxr-xr-x  7  201  201  100 2013-09-01 20:00 vmware-tools-distrib/
    root@foo:~# find ~ -type f
    /root/.ssh/authorized_keys
    /root/.bash_history
    /root/.lesshst
    root@foo:~#
    


  • Could have been worse. The kind of nuff-nuff who would put find . in a crontab is probably just as likely to use find / next time. Hell, they're next to each other on the keyboard so they must mean nearly the same thing, amirite?



  • To be fair, all of the OS files in there probably are more than 30 days old, so works-as-coded...

    Or, slightly more likely, $TMPDIR/. With the / and without setting TMPDIR.
