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 appreciated Smilie

NAME
nsend - Send messages to users or groups SYNOPSIS
nsend [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -a ] -i objectID | -c connNum[,...] | { [ -t recipient type ] -o recipient name | recipient name } message DESCRIPTION
With nsend, you can send messages to the user's workstations. nsend looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information. Please note that the access permissions of .nwclient MUST be 0600, for security reasons. OPTIONS
recipient name recipient name is either the NetWare name of the user to receive the message or the name of an existing user group on that server. You can use wildcards in this specification. -o recipient name Specifies recipient's name. This can specify user or group. -t recipent type Specifies recipient's type. -c connNum[,...] Specifies connection numbers of recipients. You can use this option as workaround to deliver messages to directory services users. -i userID Specifies recipient's object ID. You can use this option as workaround to deliver messages to directory services users. message message is the message to be sent. Please note that this has to be a single command line argument. If you want to send a message that contains spaces, you have to quote them on the command line. For example, to annoy your system administrator, you should try nsend supervisor 'I know how this works!' Program first searches (wildcards allowed) bindery with recipients name and type. If user is found, message is sent to this user, if group is found, message is sent to this group. Other object types are ignored. If no suitable object was found in this phase, connection list for specified object is retrieved (no wildcards allowed) and message is sent to this object (including print servers and so on). No expansions on group is done this time. -a By default, nsend prepends 'From ....' text to message. You can suppress this by adding -a to command line. -S server server is the name of the server you want to use. -U user name If the user name your NetWare administrator gave to you differs from your unix user-id, you should use -U to tell the server about your NetWare user name. -P password You may want to give the password required by the server on the command line. You should be careful about using passwords in scripts. -n -n should be given if specified user does not have password. If neither -n nor -P are given, nsend prompts for a password. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. BUGS
Directory services connection are not supported yet. Options -c, -i and -o cannot be used together. If user is specified multiple times (using wildcards in group specification or by repeating same number in -c), message is delivered multi- ple times to him. SEE ALSO
