Hi all,

I think I might have found my answer from another post but I still want to run this by everybody first just in case I should be checking something else also.


I have a bash script written to go out and run perl script that collects data from a couple sensors then is supposed to populate a mysql database.

This script runs perfectly from the command line but will not function from a crontab job.

Below is a copy of the script and a copy of the crontab. From the other post it looks like I need to change the #! /bin/bash to #! /bin/sh is this correct? I'm logged in as root by the way and its being run on FC5.

Bash script:

#! /bin/bash
# script to run the digitemp_mysql.pl program

cd /root/digitemp-3.5.0/perl/
.//digitemp_mysql.pl



Cron job:

1 * * * * /root/digitemp-3.5.0/perl/digitemp_my_sql


Thank you for your assistance in advance.

No. But anytime you are writting a script to be run via cron you should always use full paths to each command. Cron may not have the same $PATH as a normal user. In fact I normally unset the $PATH variable first thing, just to make sure I wont try and rely on it.

eg; Instead of...

you would need to use...

Im not sure why your not just running this Perl script striaght from cron though? Why do you need the bash script at all?

I was also running into problems getting the perl script to run from cron also LOL. I wanted to try running it as a script then have the script run from cron. I have no issue running it directly if I could get it to. the command I was giving cron was: /root/digitemp-3.5.0/perl/perl digitemp_mysql.pl

Any thoughts on this is also appriciated. As you probably guess I'm a real newbie to all this linux and script stuff.

Figured out why I wasn't getting the crontab job to run every minute like I wanted. I thought 1 * * * * would run every minute not one minute past every hour.

After discovering I had 9 hours of data recorded today when I got home I noticed they were all stored at XX:01. I looked at the cron instructions a litte more and figured out what I really wanted was 0-59 0-23 * * * (command).

Thanks to everybody who looked at the post!!

Being new to linux is so much fun LOL
