Grep command is not working when put into cron

Hi,

I worte a script which runs perfect when i execute it manually. But when i scheduled into cron the grep command alone is not working.

the sample script,

/usr/bin/grep FTP $subfile > /tmp/tfsrec.dat
tfs=`echo $?`
if [ $tfs = "0" ]
then
echo "FTP FOUND"
else
echo "FTP NOT FOUND"

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

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
