Has your file /sllpg.sh executable permissions?

try adding >>/tmp/expectlog.txt

You really want this script to execute every minute?

More than likely there are some variables missing from cron's environment. PATH is a usual one to get missed.

Check all of the called scripts and make sure that the full path to all executables is used.

If it doesn't try posting your various scripts so we can help to debug...

Cheers,

Check the cron log and the mail for the user, error will reported there.

first thing to suspect the path.(give full path).Then redirect the output to a log file >>log.txt.

Check the /var/log/cron too

Hi,

You're asking us to try and debug stuff without being able to see the code you've written... we're not psychic !

Have you checked the cron log files as suggested ? Do they tell you anything ?

A quick Google for expect threw up this page:

http://expect.nist.gov/FAQ.html#q26

is that relevant to you ?

Cheers,

Rob
