For instance, I have a large filesystem that is filling up faster than I expected. So I look for what\'s being added:
find /rapidly_shrinking_drive/ -type f
You could also use ls -l to find their size, then awk to extract the size:
ls -l
awk
find /rapidly_shrinking_drive/ -name "offender1" -mtime -1 | ls -l | awk '{print $5}' | sum
