That sounds entirely too long. A misbehaved app can do that, or problems
with the window manager, or even malicious intent. Try instead of
listing all things, list them in groups, e.g.:
ls -ald [a-d]*
ls -ald [e-l]*
ls -ald [m-r]*
ls -ald [s-t]*
ls -adl [u-z]*
Use rm -Rf on groups that you don't think are a problem. With that many
temp files, I'd be willing to say "this shouldn't be", and wipe them. Or
maybe better yet, create a directory: /tmp2, then use mv, and do for
mv [a-d]* /tmp2/
Then examine them. It isn't necessarily something malicious going on,
but you need to find out why this is happening. I would be at least
somewhat suspicious. It probably isn't SuperForker, since it doesn't
pile lots of files in one directory, it instead creates subdirectory
after subdirectory as one deep subdirectory. Find out who owns those
files, and what group they are when you find something obviously wrong.
Look for dates as well, try to find a pattern. If necessary, use rm -f
on a group, you can't let that many files sit in tmp, it isn't "right".
