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 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.

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.
