WTF Is this????


# The temp files are for storing working results so we don't call commands many
# times (gives inconsistent results, maybe adds load on things I don't want to
# such as RAID controllers).  They must not exist -- if they did, someone would
# symlink them to /etc/passwd and then run this program as root.  Call this
# function with "rm" or "touch" as an argument.
temp_files() {
   for file in /tmp/percona-toolkit /tmp/percona-toolkit2; do
      case "$1" in
      touch)
         if ! touch "${file}"; then
            echo "I can't make my temp file ${file}";
            exit 1;
         fi
         ;;
      rm)
         rm -f "${file}"
         ;;
      esac
   done
}
