If I wanted to schedule a perl script to run every weekday at 1800 hours, should I setup a cron job. once I do so, if I want to cancel it, how do I undo it. Do I have to just type this at the shell prompt to set up:
Code:
0 18 * * 1-5 root /home/test.pl

I have a script to record a weekly radio show from a Sydney radio station.I am in Brisbane.Sydney and Brisbane are both in the same time zone but Sydney(NSW) bounces around on daylight savings time and Brisbane(QLD) does not. Is there a way to specify a timezone for a specific job in the crontab file? If so what would be the format for Sydney so it follows the daylight savings time changes? Right now I will just change the cron schedule when Sydney goes on and off DST.

View 2 Replies View RelatedSome of you are probably not going to believe this, but I've been using Linux for like four years and have never used cron for task scheduling before. Now I want to and I'm not sure how to do it. Could somebody link me to some good info? The results of a Google search were kinda confusing.

*/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.

I'm trying to set up a simple backup script with cron.
In "crontab -e" (and sudo crontab-e - I tried both) I enter "0 22 * * * /home/USERNAME/.backup.sh", with the hope that it will run the script at 10pm each day. The srcipt work fine if I run in a terminal. why it won't work? It's bound to be something obvious....

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:

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.
View 2 Replies View RelatedI recently reinstalled the B module for perl. Now I found out it didn't just do that, it installed a whole new copy of perl into /usr/local/bin/perl. When I type 'which perl' at the terminal, it says '/usr/local/bin/perl' instead of '/usr/bin/perl'. Normally, this wouldn't bother me. But I installed the one in local/bin without threading support. The one that comes with the system already is build with threading support, which is why I want to switch back to the system perl, and possibly remove the one in /usr/local/bin.
So how do I change it so that the result of 'which perl' returns as '/usr/bin/perl'? And what do I have to do to remove /usr/local/bin/perl?
The reason I need threading support is because I'm designing a file copier that copies several chunks of a file simultaneously to speed up the copying process. Guaranteed a useful script if it works.
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 am new here and want to lern CentOS. Current I have installed CentOS 5.5 x64 and Perl 5.8.8. Now i have install Perl 5.12.1 which located to /usr/local/bin/perl. But how I can move it to /usr/bin/perl so root based on Perl 5.12.1?

I'm new in perl programming and linux OS. What is the difference between perl and perl-devel? What does mean devel? Iwant to install Catalyst and before install as required I have to check if make, gcc and perl-devel are installed in my system. make and gcc are installed. But I have to install perl-devel. First I searched for make, gcc and perl-devel in YAST Software Management and search did not find perl-devel. I visited the software.opensuse.org and wrote "perl-devel" and searched. The result was many similar zips with a prefix perl-devel and I can not choose one for needed perl-devel.

View 2 Replies View RelatedI am wondering about scheduling audio playback under Ubuntu. The background is this: My birthday is fast approaching, and I always try to do something to remember the best birthday gift I ever received, that being the Apollo 11 mission; Neil and Buzz landed on my 12th birthday.
Anyway, I have a wagonload of audio from nasa.gov and would like to schedule the MP3s to play in real time. 'at' won't do it, at least with 'mplayer'; I've tried. I suspect that because there is no controlling terminal for jobs run under 'at', the audio has no place to go. Is there some way to get a controlling terminal for these audio playback jobs, or specify a destination to some player?

I was searching for many time but haven't found any solution. Cron would be great, but it allows only steps in range 1-59 minutes. Is there any mode to run something exactly every 73 minutes?
The second i need (the same problem) to run program little more than every 12 hours, it might be in steps of 12 hours and 4 minutes (but 13 hours is much too much).
