Run remote command and send email
I am currently try to write a simple script with the following condition, but so far not having luck as the exit code would always be 0.
  1. Run remote command to read a file and grep for test word.
  2. if test word is in the file, send email.
  3. if not, do nothing
  4. also possible to ssh to multiple servers in one script?
Any help would be greatly appreciated. Thank you in advance!

Code:
#!/bin/bash
date=`/bin/date +%Y%m%d%H%M%S`

email_to="test_email@xxx.com"
email_subject="subject"
email_body="email body"

server="Host.google.com"

/usr/bin/ssh "$server" "cat log`date +"%m%d"` | grep test" >/dev/null 2>/dev/null

if [ $? -eq 0 ]

then
        echo "$email_body" | /bin/mailx -s "$email_subject" "$email_to"
        exit 1
fi

exit 0

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
