Cron jobs
Hi,
I am trying to figure out cronjobs setup on a linux server. When i do crontab -u -l , some output displays. Some jobs have a # in front of them but 1 last job has 0 22 ** 1-5/directory/ cache, etc.
How can I stop all jobs for the 5th ?
Thanks

stop for just 1 day; how can I remove it from this line?
0 22 * * 1-4 /directory/ cache
take out Aug 5th from running
0 22 * * 1-4 /directory/ cache
take out Aug 5th from running
there is no straight way. In your script, you can always at the beginning check for date 5 Aug and don't run script.

That 1-5 is referring to day of week numbers, where 0=sunday, 1=monday etc.
So if you want to stop all jobs for a certain date, you have to determine the day of week number for that certain date and then adapt the 1-5 to 1-4 for your case (it is a coincidence that Aug 5th is a Friday so day number 5).
A different approach is that you disable the crontab for a user completely by removing the crontab entries and restoring them the next day.
To save entries: crontab -l > your_crontab_file
To remove entries: crontab -r
To restore entries: crontab your_crontab_file
Be sure to check contents of file your_crontab_file before using -r or you'll loose your entries.

@Omar - No, author is posting:
0 22 * * 1-5
so 1-5 is the fifth field.

Eric, any update? Need further assistance?
@Gerwin, I thought your comment was about my last post where I recommended to have two crontab jobs:

@Omar, no it wasn't ;) My suggestion would be to disable crontab for the day and enable again. Not sure if we get a response though since Aug 5th was a week ago...
