Previously I had posted a question on how to make it run every 7 minutes between 7 and and 11pm.However now I found out what I really need is every 7 minuted between 7:30 and 11pm BUT it has to be every 7 minutes, it cannot reset itself on the top of every hour, so the */7 wont work.How can it that it will be every 7 minutes, so it will go at 7:30, 37,44,51, 58, 8:05, etc..
View 4 Repliesi cannot find it in the man. Is it possible to run cron job like this:
Run script from 18 00 till 5 00?
I want to run some script but only during the night time, when users are not working.
I'm running my website on a linux server. I'm using a mac. Apparently, mac mail has a bug where it creates too many imap processes.
Since I'm on a shared server with a 25 process limit, with 3 email accts x 4+ processes each = a lot of problems!
I'm trying to write a cron job to delete imap processes every minute.
I've tried two things
1) following this blog's advice [URL]
Code:
killall imap
i realised it was imapd not imap, but i tried another method anyway
2) create a kill-imap.sh file in my server folder.
Code:
#!/bin/bash
/usr/bin/killall imapd
then executing the file from the cron command /kill-imap.sh
both these cases, it didn't seem to work!
I would get a daemon emai reply with
imapd: no process killed
just to give more info, the existing imap processes look like this
/usr/lib/courier-imap/bin/imapd /home/sitename/mail/sitename.com/emailusername
honestly, I'm not too experienced in this, and i've searched the net without luck. can anyone advise what i'm supposed to do to kill these imap processes every 5 min via cron job?
How would I set a cron job to run every 7 minutes between 7pm and 11pm?

I wish to run a cron job every half hour, where exactly do I put the job? The reason I am asking is that I am used to entering jobs into crontab, I am not used to using fedora and its cron layout.

I have cron jobs running and the timing is critical, because I'm running Nessus scans on production servers. If I hit them at the wrong time, I'm toast. But when I check the cron log, I see that it is an hour off. Here is the output for the command "clock":
Wed 31 Mar 2010 03:01:26 PM CDT -0.257677 seconds
And this is the tail of the cron log:
Mar 31 16:00:01 nes-001 CROND[8790]: (root) CMD (/Nessus/Targets/NessusScriptDataCenterScan.test)
Mar 31 16:01:02 nes-001 CROND[8822]: (root) CMD (run-parts /etc/cron.hourly)

Cron thinks it is 4:00 p.m., but it's really 3:00 p.m. How do I tell Cron what time it is? (Stopping and restarting the crond service did not change it.)

I have now the followig to test (every 16th minute of the hour, write test to a file), but it doesn't show up. When I write out the cron, it is done to the file: /tmp/crontab.QXsBIO/crontab . How to make cron work? It must be very easy, but I have real troubles getting it fired up.

I want to create 2 cron jobs daily

I tried but only 1 cron job can able to run at a time.
I've run into a strange problem on one of the servers I maintain. It's running CentOS 5, fully up to date. The server has Monit installed via RPMforge, and runs Postfix as its MTA. Every day at about 4:20am, when cron is running, Monit loses its connection to Postfix. As far as I can tell, nothing is actually going wrong with Postfix and it's always restarted just fine. I run a couple of Debian servers with very similar setups, and the problem does not occur on them.
Perhaps related, other daemons on the CentOS box often lose their pid files at the time when cron runs, which results in Monit thinking they're not running. One service in particular (zarafa-dagent) is so bad for this that I've had to completely disable monitoring of it in Monit. Again, this problem doesn't occur on the Debian boxes I maintain.The problem isn't hugely urgent as everything still runs fine, but it does mean that pretty much every day I get false positive mail alerts from Monit, which is (a) annoying and (b) makes me more likely to miss a real alert.

I have a crontab on my vps running every minute that checks to see whether or not a certain port is open on localhost. If the port isn't open, it should run the php script to restart the program. However, I require the use of screen to be able to interact with the program whenever I reconnect to the vps through shell.The problem is, screen is being a pain by saying "Must be connected to a terminal."This is the php script:

My root Vixie cron crontab is set to perform a system snapshot via fsarchiver: 0 0 * * * fsarchiver savefs -o -A /backups/p30_root.fsa /dev/sda2 /dev/sda3 The command itself works fine, generating about a 7G snapshot of my Suse server. I then wish to rsync this to a NAS I have located in another building: 0 3 * * * rsync -av -e ssh --delete /backups/ root{at address}:/DataVolume/os_backups/
(yes, I'm rsyncing as root. I absolutely loathe it, but I got thrown into an quasi-SA position with a ridiculous to-do list and no time to do it. I'm having to make things just work and then go back and try to improve them/learn how. I couldn't make it work in a non-root way quick enough, so for now I'm having to cron rsync jobs as root because of all the differing file permissions on this samba/MySql server. I set the NAS to only accepts ssh from the server IP, and we're behind a campus firewall... It's serious trial by fire.) The crontab also has rsync commands for the samba areas, our specialized chemistry software and affiliated MySQL databases............

I need to change the time displayed in the task bar from a 24 hour clock to a 12 hour format. I could not find the relevant settings in OpenSuse 11.2 and same is the case for 11.3 as well.
how to make the change? I have tried System Settings ---> Computer Administration ---> Date & Time; but I was not able to make the desired change.
