- try changing to this block of code:
Code:
if [ -z "${arg_Smirs+X}" ]; then
flnm="${txPath}/${flnm01a}"
elif [ -z "${arg_Capav+X}" ]; then
flnm="${txPath}/${flnm02a}"
elif [ -z "${arg_Igmfn+X}" ]; then
flnm="${txPath}/${flnm03a}"
elif [ -z "${arg_Segpi+X}" ]; then
flnm="${txPath}/${flnm04a}"
elif [ -z "${arg_Exads+X}" ]; then
flnm="${txPath}/${flnm05a}"
elif [ -z "${arg_Isemi+X}" ]; then
flnm="${txPath}/${flnm06a}"
elif [ -z "${arg_Cocpl+X}" ]; then
flnm="${txPath}/${flnm07a}"
elif [ -z "${arg_file+X}" ]; then
flnm="${txPath}/${arg_file}"
else
flnm="${txPath}/${flnm04a}"
fi

I want to check if the option is set so I can then assign the variable flnm.

But I do not know how I can do it. I expected the -z expressions to work.

I have also tried the using -v and removed all the code after the if statement. Still same problem.

Code:
if [[ -v arg_Smirs ]]; then
  flnm="${txPath}/${flnm01a}"
elif if [[ -v arg_Capav ]]; then
  flnm="${txPath}/${flnm02a}"
elif if [[ -v arg_Igmfn ]]; then
  flnm="${txPath}/${flnm03a}"
elif if [[ -v arg_Segpi ]]; then
  flnm="${txPath}/${flnm04a}"
elif if [[ -v arg_Exads ]]; then
  flnm="${txPath}/${flnm05a}"
elif if [[ -v arg_Isemi ]]; then
  flnm="${txPath}/${flnm06a}"
elif if [[ -v arg_Cocpl ]]; then
  flnm="${txPath}/${flnm07a}"
elif [[ -v arg_file ]]; then
  flnm="${txPath}/${arg_file}"
else
  flnm="${txPath}/${flnm04a}"
fi

Solved.
Code:
elif if

Could not see it for some reason !!!

I am using [ -v arg ]; and I am wondering whether I would be better off with [[ -v arg ]];

Perhaps not, as I do not need globbing for checking existence of variables

Code:
if [ -v arg_Smirs ]; then
  flnm="${txPath}/${flnm01a}"
