.SH NAME
.B mktd
\- try hard to safely create a temporary directory in a POSIX-compliant way
.SH SYNOPSIS
.B mktd
.br
.B mktd
foo
.SH DESCRIPTION
.B mktd
creates a temporary directory with a strong attempt at a random name in $TMPDIR
(defaults to /tmp), with a restrictive umask for the user running the script,
into which it should be safe to place temporary files.
.P
The author makes no guarantees about security, but this should be a lot safer
than just using a /tmp/$$ file.
.P
You could use it in a script like this:
.P
    td=
    cleanup() {
        [ "$td" ] && rm -fr -- "$td"
        if [ "$1" != EXIT ] ; then
            trap - "$1"
            kill "-$1" "$$"
        fi
    }
    for sig in EXIT HUP INT TERM ; do
        trap "cleanup $sig" "$sig"
    done
    td=$(mktd myprogram) || exit
