I need to quickly and temporarily disable a particular job in crontab under linux. How can I do that?
The quickest way would be to edit the crontab file (which can be done by typing crontab -e) and simply comment the job you want disabled. Comment lines in crontab start with a #.
0 0 1 * * this_job_i_want.sh
# uncomment below to enable
# 0 0 2 * * this_job_i_dont_want.sh
Simply edit your cron time to run every February 30. ;)
* * 30 2 * this_job_will_never_run.sh
This is especially helpful for those using a GUI to manage their cronjobs (i.e. cPanel, Plesk, etc.) and don't have access to the actual cron file.

What would be the cron expression for "nth second of every minute"?
For example, for every 5th second of every minute, the cron would run at 1:00:05, 1:01:05, 1:02:05 and so on.. 24x7.
I could not find any documentation for achieving this.
Thanks in advance!
This functionality is not available out of the box. What you could do is prepend your command with sleep, so it would be:
sleep 5 && /app/script.sh
Figured it out. The cron expression would be.
5 * 0 ? * *

I don't have a box to test a cron job so I am posting it here.
I want to run a job every hour between 6 am to 18:00.This is what I have tried
0 6-18/1 * * * <command>
and
0 6-18 * * * <command>
Which one is the correct way of achieving it
Both should work, but I would probably use the second one.

I am trying to set up a crontab in linux that runs every 5 minutes
I need to run the following command:
/var/local/orders/ pmtw-print.jar localhost pmtw root itsm
This is what I think I should have but doesn't appear to be working:
5 * * * * java -jar ~/var/local/orders/ pmtw-print.jar localhost pmtw root itsm
Thanks
To run every 5 minutes, use the following. The one you have would run at 5th minute every hour.
*/5 * * * * java -jar ~/var/local/orders/ pmtw-print.jar localhost pmtw root itsm

I would like a cronjob that runs every 5min with the condition that it doesn't start at time 0.
Current schedule is:
*/5 * * * *
However, this will kick off the script at 00:00. I need something like (5-60)/5 * * * *
Thanks!
I'm not sure there is a way to do this in cron. You might be better off leaving the schedule as is, and checking the time in the beginning of your script, and using a condition to exit the script if it is not supposed to run at that time.

Open root's crontab for editing in default editor:
sudo crontab -e
Then add this line:
*/10 * * * * echo '' > /var/log/httpd/access_log
