[ rmtmp: remove temporary files ]

I was prototyping a project that was creating a temporary file for
every second in a certain time range of timestamps, running through
about 4500 timestamps / second. However, I managed to forget to clean
up those temporary files, leaving me with over three million temp files
in my /tmp. find(1) was taking entirely too long at about 300 files per
minute, so while it was running, I hacked together a custom utility
in C to do it much faster. It removed about two million files in under
five minutes.

In short, rmtmp(1) steps through the directory entry for /tmp. When it
finds a regular file, it checks to see if it starts with the prefix
passed in; if so, that file is removed.

This is a fairly trivial utility that took about fifteen minutes to
write, and it's aimed at a specific use case. It is being distributed
in the offchance others find it useful.


Building the code can be done with either make(1) or mk(1); while mk(1)
is preferred, a Makefile has also been provided.


usage:
	rmtmp [-d tmpdir] [-v] <prefix>

for example, if your program has called mkstemp("myprogXXXXXX"):
	rmtmp myprog
will remove all of the temporary files generated. The -d flag allows the
user to specify the temporary directory the temp files are stored in. The
-v flag tells rmtmp(1) to use verbose mode, reporting the number of
files removed every 1000 files.
