Making tmp Files and Directories On The Command Line

Use ``mktmp``

See the examples from ``man mktmp``

tempfoo=`basename $0`
           TMPFILE=``mktemp /tmp/${tempfoo}.XXXXXX`` || exit 1
           echo "program output" >> $TMPFILE

To allow the use of $TMPDIR:

tempfoo=`basename $0`
           TMPFILE=``mktemp -t ${tempfoo}`` || exit 1
           echo "program output" >> $TMPFILE


In this case, we want the script to catch the error itself.

tempfoo=`basename $0`
           TMPFILE=`mktemp -q /tmp/${tempfoo}.XXXXXX`
           if [ $? -ne 0 ]; then
                   echo "$0: Can't create temp file, exiting..."
                   exit 1
           fi

On mac, it'll use a directory something like:

/var/folders/dx/ypcmcxd53mb731bpkp_2p_vh0000gn/T/

That's what's set in $TMPDIR

It'll use ``$_CS_DARWIN_USER_TEMP_DIR`` if that's set instead. If neither of those are set, it'll fall back to `/tmp`
