Im a newby user writing my first shell script, and i trying to make it run with the cron utility.

If i run this code manually, the code was sucefull runned, but, when i put in this task in the crontab, the mail dont cant sended.

When i write a ps command, my task look like this:

root      2647  0.0  0.0  1584  640 ?        S    18:35   0:00 CROND
root      2648  0.0  0.0  2128  932 ?        S    18:35   0:00 /bin/bash -c /root/rmssProject/./rmmsConnection.sh
smmsp     2650  0.0  0.0     0    0 ?        Z    18:35   0:00 /usr/sbin/sendmail -FCronDaemon -i -odi -oem root
root      3317  0.0  0.0  1796  500 ?        S    18:38   0:00 sleep 2s

...and the mail cant sended. the process stay in stand by, and i dont now why, the cron cant process my script.

The uname command showme this:

Linux host.example.com 2.4.21-9.0.1.ELsmp #1 SMP Mon Feb 9 22:26:51 EST 2004 i686 i686 i386 GNU/Linux

And my code is this:

# Mail subject
SUBJECT="IP'S state"
# to mail's
EMAIL_LIST="ayudamicro@hotmail.com"

ssh [email]script@xxx.xxx.xxx.xxx[/email] < outCommand.ptx | cat > listPop.pop
grep -i '^[a-z][0-9{3}\-][0-9{6}|a-f{6}]' listPop.pop > listCleanPop.pop
LINE=$(wc -l listCleanPop.pop | gawk '/[0-9]+ +*/ {print $1;}')
while test "$LINE" = "0";
do
        ssh script@65.200.191.232 < outCommand.ptx | cat > listPop.pop
