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 -mtime -1 -ls | less
And I find, well, lots of stuff. Thousands of files of six-seven types. I can single out a type and count them:
find /rapidly_shrinking_drive/ -name "*offender1*" -mtime -1 -ls | wc -l
but what I'd really like is to be able to get the total size on disk of these files:
find /rapidly_shrinking_drive/ -name "*offender1*" -mtime -1 | howmuchspace
I'm open to a Perl one-liner for this, if someone's got one, but I'm not going to use any solution that involves a multi-line script, or File::Find.
Since OP specifically said:
I'm open to a Perl one-liner for this, if someone's got one, but I'm not going to use any solution that involves a multi-line script, or File::Find.
...and there's none yet, here is the perl one-liner:
find . -name "*offender1*" | perl -lne '$total += -s $_; END { print $total }'
