then
echo "Validate the file" | mailx -s " There are errors : " ${EMAIL_LIST}
else
echo "No Errors" > log_file
fi


When I am executing the script I am getting the below error
Code:
 [: -rw-r--r--: integer expression expected

Please let me know where I am doing it wrong.

And if we compress the file and email, can we extract in windows using the normal winzip software?

Thanks and Regards,
Mora
The file size in ls -l output is field 5; not field 1. Try:
if [ `ls -l /tmp/file.txt | awk '{print $5}'` -eq 0 ]
but as RavinderSingh13 suggested (but I think he reversed the desired outcome), a much more efficient test is:
Code:
if [ ! -s /tmp/file.txt ]

mlmmj-unsub(1)						      General Commands Manual						    mlmmj-unsub(1)

NAME

       mlmmj-unsub - unsubscribe address from a mailinglist run by mlmmj

SYNOPSIS

       mlmmj-unsub -L /path/to/list -a john@doe.org [-b] [-c | -C] [-d | -n | -N] [-h] [-q] [-r | -R] [-s] [-U] [-V]

       -a: Email address to unsubscribe

       -b: Behave as if unsubscription is due to bouncing (internal use)

       -c: Send goodbye mail

       -C: Request mail confirmation

       -d: Unsubscribe from the digest version of the list

       -h: This help

       -L: Full path to list directory

       -n: Unsubscribe from the nomail version of the list

       -N: Unsubscribe from the normal version of the list

       -q: Be quiet (don't notify owner about the unsubscribe)

       -r: Behave as if request arrived via email (internal use)

       -R: Behave as if confirmation arrived via email (internal use)

       -s: Don't send a mail to the address if not subscribed

       -U: Don't switch to the user id of the listdir owner

       -V: Print version

DESCRIPTION

       This  utility  is  used to unsubscribe people from the specified mailinglist. It will remove the specified email address from every file in
       the <listdir>/subscribers.d/, <listdir>/digesters.d/ and <listdir>/nomailsubs.d/ directories (or if the -d, -n or -N switch is given,  only
       the one relevant directory).

       Unless  the -U switch is used it will switch its user id to the user id owning the list directory. This is done to make sure that new files
       created are having correct permissions.

       Normally a mail is sent to the person being unsubscribed if the address is not subscribed to the list. If the -s switch is used such a mail
       will not be sent.

       When neither -c nor -C is specified, unsubscription happens silently from the point of view of the subscriber. When -q is specified, unsub-
       scription happens silently from the point of view of the list owner. Use of -s  is  recommended	to  ensure  you  don't	spam  unsubscribed
       addresses by accident.
