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 !!!
--- pdated at 01:06 AM ---

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}"

locale::codes::langfam5.18

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
