"Error running grep on Remote Servers"

Error running grep on Remote Servers

Im running the below command

Code:
sshpass -p mypassword ssh -t user1@server2 /bin/bash -c 'echo "mypassword" | sudo -S -l; echo "$?#`grep -iE "user66|dbuser|tomcat|splunk|stash|jira|user2|docadmin" /etc/passwd`"; exit'

Below is the error I get: Output:

Quote:
User user1 may run the following commands on server2:
(ALL) ALL, !/bin/su
ksh: user66: not found
ksh: dbuser: not found
ksh: tomcat: not found
ksh: splunk: not found
ksh: stash: not found
ksh: jira: not found
ksh: ^J: not found [No such file or directory]
ksh: docadmin /etc/passwd: not found [No such file or directory]
I run this command across a set of 500+ servers.

I also tried using egrep but it still did not work.

Note: Strangely grep -iE "user66|dbuser|tomcat|splunk|stash|jira|user2|docadmin" /etc/passwd works fine with ksh shell when i manually fire it from the remote server2

I m looking for a solution by which I could enforce to either use bash shell on remote servers or have a grep / egrep / fgrep / ggrep or by specifying complete path to a particular grep command that works across different flavors or unix Linux servers.

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
