To make the shell script setuptex more robust I would add at the beginning:
set -o errexit
set -o nounset
function isVarSet() {
if [[ ${#} -ne 1 ]] ; then
fatal "${FUNCNAME} <VARIABLE-NAME>"
return
fi
declare -p ${1} &>/dev/null
return
}
And use:
if ! isVarSet PS1 ; then
instead of:
if [ "x$PS1" != "x" ] ; then
I use in my script that calls setuptex
set -o errexit
set -o nounset
and that breaks the script. With my change there is no problem.
