But i suspect that the below command always return 0 as status code regardless of the string "Job Status : RUN FAILED (3)" in the output:
Quote:/opt/app/dstage/DataStage752/Ascential/DataStage/DSEngine/bin/dsjob -server servername -user uname -password pwd -jobinfo $job_name | grep "Job Status : RUN FAILED (3)"

so $? always equals to 0 and all the jobs will be written into file.

The grep command should always exit with a non-zero code if the string was not found in the input text. Are you executing any commands between the grep and your if statement? If so, the $? value will be replaced with the value from that command and might thus always appear to be zero. Ensure that your if statement is immediately following the statement with grep. If it is, and you are still having problems, please post the whole script (it looks like you cut bits and pieces in your original post).

zgrep

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.
