How do I delete a certain file in linux if its size is 0. I want to execute this in an crontab without any extra script.
l filename.file | grep 5th-tab | not eq 0 | rm
This will delete all the files in a directory (and below) that are size zero.
find /tmp -size 0 -print0 |xargs -0 rm
If you just want a particular file;
if [ ! -s /tmp/foo ] ; then rm /tmp/foo fi
