Supported Platforms

At this time, stmpclean works on BSD and Linux.  It has been reported
to work on Solaris, IRIX, and SCO, but I have no way of verifying this.


	Installation

To build, say ``make''.  To install, execute the command ``make
install'' and then read the manual page.  You can also read the
pre-formatted manual page before installation in the file stmpclean.0.


	Rationale

People do stuff like

find /tmp -type f -atime +3 -ctime +3 ! -name '.X*-lock' -exec rm -f -- {} \;
find -d /tmp ! -name . -type d -mtime +1 -exec rmdir -- {} \; >/dev/null 2>&1

as root in /etc/crontab (or in daily maintenance scripts).

Don't ever do this.  This can be easily tricked into deleting
arbitrary files on your system!

People also run nifty Perl scripts that overcome this problem.  Well,
in case there is an attack, they won't delete your precious
/etc/ftpusers or whatever you guard most.  They'll just fork 10000
children each trying to allocate 2MB of memory.  Good luck.

This program solves these problems.


	Further Information

The distribution is accompanied by a FAQ file.  It should answer
most common questions.  If your question isn't answered, or if you
have a problem with stmpclean, or a suggestion, or a bug report,
or a patch, send it to me (see address below).
