beginner bash script issues with cron

i did the following:

#!/bin/bash
pacman -Syu | tee -a /update.log

and i set it with permissions of 4755 and it runs but says not permitted unless root but it should since i gave it SUID bit. i want it to run each morning and just grab all the updates available.

i did this and installed it in my crontab but maybe if i put it into the root crontab?

Unattended upgrades are strongly discouraged, but if you must, use sudo. Also, pacman already has a log.

Re: beginner bash script issues with cron

im using this to test writing scripts since i dont know of anything else useful. also where should i put them? should i create a /bin in my home directory?

@archlinux2011:  For security reasons linux ignores the SUID-Bit on scripts.

How often will you read the log?

Re: beginner bash script issues with cron

i was using the log to test things. i rewrote it to be this:

#!/bin/bash
date >> /home/<username>/dateout.log

again just to test things and its in crontab as

*/*5 8 * * * /home/<username>/bin/dateout.sh

and it doesnt seem to work.

this is to get used to writing scripts and becoming familiar with cron so its nothing useful just a small test.

I think you should pick another title for this thread.

I think you crontab should say

*/5 8 * * * /home/<username>/bin/dateout.sh

That'll run every 5 minutes from 8:00 - 8:55, if that's what you were going for.

Re: beginner bash script issues with cron

Read again lunar's post.  Is this a user cron job, or a system cron job.  If I missed that, I'm sorry -- I'm hurrying off to a meeting.
