First off, if you write to temporary files you should always prepare a place for these first and clean this place upon exit. Usually you can use the PID variable to make the places name unique, because the PID is always unique. I do it usually the following way (sketch only):
This way each instance of a script gets its own temp dir, puts everything it uses in there and upon exit (regardless which exit, even when terminated from outisde) it cleans up. The only way to have the temp files not cleaned is to terminate it with a "kill -9".

mktemp
MKTEMP(1) User Commands MKTEMP(1)NAME
mktemp - create a temporary file or directory
SYNOPSIS
mktemp [OPTION]... [TEMPLATE]
DESCRIPTION
Create a temporary file or directory, safely, and print its name. If TEMPLATE is not specified, use tmp.XXXXXXXXXX.
-d, --directory
create a directory, not a file
-q, --quiet
suppress diagnostics about file/dir-creation failure
-u, --dry-run
do not create anything; merely print a name (unsafe)
--tmpdir[=DIR]
interpret TEMPLATE relative to DIR. If DIR is not specified, use $TMPDIR if set, else /tmp. With this option, TEMPLATE must not be
an absolute name. Unlike with -t, TEMPLATE may contain slashes, but even here, mktemp still creates only the final component.
-p DIR use DIR as a prefix; implies -t [deprecated]
-t interpret TEMPLATE as a single file name component, relative to a directory: $TMPDIR, if set; else the directory specified via -p;
else /tmp [deprecated]
--help display this help and exit
--version
output version information and exit
