View 2 RepliesI would like to schedule a cron job to run on every first saturday of the month, so far all documentation that I have looked at, mentions only a weekly cron or a monthly cron based on the date. Is it possible to run a monthly cron based on the day of the week?

I guess other way is

i think it should be related to cron jobs.
Can anyone tell me how i change the default domain name for cron?everything i cron runs it emails from and to user@com.com
this leaves me with a massive list of failed mails in postfix.i have mailto on my main crontab but i cant do it on all of them.
It seems that cron is not upgrading my Ubuntu 8.04 LTS Server, no GUI installed. I changed /etc/crontab and watched apt running:
Code:
ps -A | grep apt
showed it for a long time,
Code:
sudo tcpdump tcp
showed communication with canonical sites,
but:
Code:
top
did not show any apt using CPU

I put in my cron entries to run my backup script which rsyncs my data to my 2nd drive, however on a hunch I checked my backup drive which mounts automatically via fstab and I realize it had not ran in a while. I checked cron and there were no entries for it. I got to wondering if I should ever be worried about a cron update coming down and over-writing my existing cron file with the backup entries in it to run.

I have added some executable scripts to /etc/cron.daily but don't get the stdout/stderr output from them as mail (or anywhere else I have found). At least one of them is running (because I can see that it has added a file to the disk).
The peculiar thing is that I do get the output from /etc/cron.daily/0logwatch (part of the logwatch package) as an email each day.
The MAILTO line in /etc/crontab is "MAILTO=root" (unchanged from default). Same for /etc/anacrontab.
I do have an alias at the end of /etc/aliases which redirects root's mail to my own account, but this alias works fine for mail I send manually. (It also appears to work fine for the output from the file /etc/cron.daily/0logwatch.)
I have set up a cron in /var/spool/cron/root
*/15 * * * * /usr/bin/phplist.sh
I can see in /var/log/cron that it is running every 15 minutes but it has no effect. It is not doing the commands in the bash script.
If I run /usr/bin/phplist.sh right in the shell it works great.
After a lot of work, I think I have successfully written a script that displays the last login times of all users on a system. It gets the list of users from the directories in the /home folder and then finds the latest entry from the 'last' command for their login times. This may be a useful script for admins out there
I am not at all sure this is the best way of doing this or that there aren't ways that this script fails. At the moment, there are no users on my test system who haven't logged in so I am not actually sure that feature works. I imagine it does though. Please feel free to copy/use and/or criticize/correct. I would love it if we can make this script better. Take a look:

View 2 Replies View RelatedI used k3b to write a music CD on my Asus laptop. I then put it back in the drive, and Kubuntu told me that it was blank. Yet when I brought it over to a different machine, or to a non-computer CD player, it played correctly. The files on the CD are WAV, not MP3.
I've heard of problems where you write a CD in one machine and then can't read it in a different machine, but this is the other way around! The originating machine can't read it but the foreign machines can. I don't understand that at all.
The default writing speed is 24X. I tried lowering it to 16X, but that had no effect.
I am trying to debug a script that another person wrote. I am not very strong understanding awk.

I know awk is doing some kind of manipulation of the acsii file ${origfile}, just not sure what.
I installed squid on my machine, and for a while it was starting up automatically when the computer would turn on, and I would only have to reconfigure on ip-up for the new dns, etc.Now for some reason, I notice that squid isn't even started.To fix this, I wrote a start up script in /etc/rcS.d/ that runs:/etc/init.d/squid3 startAnd I notice it still isn't starting.So I write "/etc/init.d/squid3 start" and put it in my ip-up.d/ script.Everything in the script is being executed, but the squid server.I've tried reinstalling squid... what am I missing? where does the computer start these services?

I can execute it fine from the command line, but I it doesn't seem to work when I schedule it with crontab. In fact, I can't make any gui by scheduling it, not even something like gedit or firefox.
