...I tried it out on the 3 servers that I need to run the script for and the second suggestion you mentioned only works for KSH93.

Good idea on using the return instead of exit. Just to clarify, the return will always return to the calling sub, correct?

BTW, I also just discovered that if I have more than 4 select options to choose, it wraps into the next column, is there any way to control this behavior?

Thanks again for reply.

Yes, ksh didn't add support for $'...' until ksh93.

I'm not sure what you mean by calling sub. In my example, menu_main was called from the main body of the ksh script. A return from a ksh function or dot script will return to the invoking shell script.

I'm also not sure what you mean by wraps into the next column. If you mean that adding more choices to the select makes that line in your script wider than your screen width or editing window width, you can use a
backslash newline to continue your choices onto the next line. For example:

Code:

#!/bin/ksh
menu_main1() {
        PS3="
::  Please choose a VALID option : "
        printf "\n\n"
        select choice_main in "Generic SA" "Refresh Tasks" "Others" \
                "Do Something Else" "Return"
        do
                case $choice_main in
                ( "Generic SA" )
                        echo "Generic SA"
                        clear
                        menu_db_admin;;
                ( "Refresh Tasks" )
                        echo "Refresh Tasks";;
                ( "Others" )
                        echo "Others";;
                ( "Do Something Else" )
                        echo Do Something else;;
                ( "Return" )
                        return;;
                esac
        done
}
echo about to call menu_main1
menu_main1
echo menu_main1 has returned

dcsort

DCSORT(1)					      DICOM PS3 - Make sorted list of images						 DCSORT(1)

NAME

       dcsort - ACR/NEMA DICOM PS3 ... DICOM PS3 - Make sorted list of images

SYNOPSIS

       dcsort  "  inputfile1  [ inputfile2 ... ]" [ -v|verbose ] [ -vv|veryverbose ] [ -vvv|veryveryverbose ] [ -index ] [ -show ] [ -interval ] [
		 -tolerance mm ] [ -check ] [ -checkFoR ] [ -descending ] [ -sortby|k  attributename ]

DESCRIPTION

       dcsort reads the named dicom input files and sorts them by the specified sort key.

       The sort key should be a single valued numeric attribute, with the exception of ImageOrientationPatient and ImagePositionPatient which  are
       handled as special cases.

       There is no output by default unless the index or verbose options are specified.

OPTIONS

       The output and errors go to standard error.

       The basic input switches are described in dcintro(1). Options specific to this program are:

       -index
	      Creates a first column of output that is the index in the sort order, starting from 0, and a second column that is the filename.

       -show
	      Show the value of the sort key after the file name with the -index option

       -interval
	      Show the interval between values of the sort key, or an error if not equal

       -tolerance mm
	      The tolerance value in mm to use when comparing intervals between slices; defaults to +/- 0.01 mm if unspecified

       -check
	      Check that all the images are from the same series.

       -checkFoR
	      Check that all the images have the same Frame of Reference (UID).

       -descending
	      Sort in descending, rather than the default ascending, order.

       -sortby|k  attributename
	      Specify attributename as the sort key.

ENVIRONMENT


EXAMPLES


       % dcsort -index -sortby SliceLocation ./1/[0-9]*
       0    ./1/1
       1    ./1/2
