In bash there's select command for this kind of things.
If I'm wrong, which is always extremely possible when the matter is shell scripting, I'd really appreciate a hint from you about the solution.

Bash isn't a shell well suited to scripting at all IMHO and should be avoided at all costs.
My shells knowledge is so little that I can't discuss this topic.
But I'm a bit.. confused.

What was so wrong with my script?
And, of course, also in bash you can use an array as you've done in ksh (moreover, it had been my first think: but then select came to my mind, and it does the work, and it's much quicker. So why not use it, if bash is available?).

LOL! Smilie
Of course you're speaking to the OP.
AIX... I'm not a sysadmin, nor my job is heavily computer related. So, AIX... (AKA "blood and tears", as someone says): I - personally - have never seen an AIX system. Smilie

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
