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. -- Cecil Westerhof
Dear Cecil,
I would be glad to fix the script, but may I only ask for some simple
explanation of what your code does? (I hardly know bash.)
