A mega geeky awk one-liner today. Tested on Solaris under bash, so [YMMV].
Have you ever found that a filesystem is filling up fast, and dont know what is causing it? This one liner (which can be placed in a cron job if you like) is best run as a super user.
- Search for all files in the current dir and subdirs that are modified in the last 3 days;
- list them, filtering just the filesize and name/path;
- sort/order by the largest file; and
- Email you a copy of the report.
