Script works on Solaris, not on Linux

I'm in the same boat as Barbus - same exercis (https://www.unix.com/shell-programmin...ses-users.html)

The following script works on a solaris server I have access to. It doesn't however, work on the companies Linux machine. Any idea what's up? I have very little shell experience, and I can't seem to get this to work. Someting really obvious I'm missing that you vets can spot a mile off?

#!/bin/bash
#set -x

w | cut -d ' ' -f1 | sort -u | while read userID
do
while IFS=: read userIDpasswd junk junk junk userName junk
do
if [ "${userID}" = "${userIDpasswd}" ]; then
echo "userID->${userID} userName->${userName}"
ps -U ${userID}
fi;
done < /etc/passwd
done

Any help would be appricated Smilie

NAME
Test::Script - Basic cross-platform tests for scripts DESCRIPTION
The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or bin as is also commonly used) paths of your Perl distribution. Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible. That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is considered unacceptable. In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking that your module won't on some platform because of the dependency. Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform safety. FUNCTIONS
script_compiles script_compiles( 'script/foo.pl', 'Main script compiles' ); The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. script_runs script_runs( 'script/foo.pl', 'Main script runs' ); The "script_runs" test executes the script with "perl script.pl" and checks that it returns success. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. SUPPORT
