Hi all...

When i execute a program in the command line the program works ok, but when I put it on the crontab I get the following error:

From hospub Tue Jul 5 07:44:00 2005
Date: Tue, 5 Jul 2005 07:44:00 GMT
From: root@localhost.localdomain (Cron Daemon)
To: hospub@localhost.localdomain
Subject: Cron <hospub@backup> /home/hospub/INTER
X-Cron-Env: <SHELL=/bin/sh>
X-Cron-Env: <HOME=/home/hospub>
X-Cron-Env: <PATH=/usr/bin:/bin>
X-Cron-Env: <LOGNAME=hospub>

stty: standard input: Invalid argument
Erro de ioctl (preterm)

Does anyone know what it means???

Posting your crontab entry and the script/command your trying to run might help a little..

Sorry...

the name of the script is interlab and it's in /home/hospub

#!/bin/bash
/home/hospub/INTER 2>&1 /dev/null

and the crontab entry for the user hospub:

* * * * * /home/hospub/interlab

So let me get this right.. you have a scripted called INTER in /home/hospub that contains this code:

Code:

#!/bin/bash
/home/hospub/INTER  2>&1 /dev/null

So what's the point of this script? You just want it to continually run? What is this script suppose to do?

No.. no...

the script name is interlab, and that script call the file named INTER...

I want it to run for eternity...

So why are you having cron contiually run this script? What does this script actually do and why don't you make the script itself loop after starting it.. cron is not intended to continually make a script run, but to schedule commands and scripts at incremental times..

So how I make the script itself run unstopable???
