Path doesn't matter as I am using full path anyway. This is a script for NetBackup (enterprise backup application) to run a command to gather data. The command (nbdeployutil) is a two step command. You run it first for it to gather the data and then again to generate a report. I wish I could just run it once, but it doesn't have that feature. Here is my whole script.

Code:
#!/bin/bash

#This script runs the NBU NBDEPLOYUTIL command
#to generate capacity based output in the
#form of Front End (or Protected Data) Terrabytes per site.
#This script works with NBU version 6.5.x


usermail=(users email address goes here)
hostname=`hostname`
date=`date +%m%d%Y`

#Execute the NBU nbdeployutil command and send output to a file as this command
#is a two-part command. 
/usr/openv/netbackup/bin/admincmd/nbdeployutil --gather | /bin/grep nbdeployutil > /tmp/nbdeployutil_temp.out

#Set the mail_report variable by grepping out the command to run from the temp file
mail_report=`/bin/grep report /tmp/nbdeployutil_temp.out | /bin/cut -d':' -f2`

#Execute the 'report' portion of nbdeployutil and send output to a file.
/bin/echo `$mail_report` > /tmp/nbdeployutil_temp_rpt.out

#Pull the proper information out of the temp file.
mail_report=$(/bin/cat /tmp/nbdeployutil_temp_rpt.out | /bin/awk '{print $15}')

#Mail the file to the specified users.
(/bin/uuencode "$mail_report" "$mail_report") | /bin/mailx -s "$hostname NBDEPLOY $date" $usermail
exit 0

Again, it seems to fail to execute this line properly when run from cron.
Code:
/bin/echo `$mail_report` > /tmp/nbdeployutil_temp_rpt.out

The only thing special about this is that it is executing a variable. I'm open to better ways to do this if it works. If i knew perl that would probably be that better way ;(.

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/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/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

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

FILES

       /etc/shells	       lists shells on system
