Top Forums UNIX for Dummies Questions & Answers Double Check my Cron Job Post 302788425 by bakunin on Monday 1st of April 2013 07:36:02 PM

Just a few suggestions:

1. Your script should definitely not reside in "/usr/local", but in "/usr/local/bin". See the File System Hierarchy Standard, which is a very good guideline for what to place where.

2. Have you made sure you do not fall for the Cron Problem Number One?

3. You should redirect <stdout> and <stderr> in your cron line, either to a log file or to "/dev/null". Otherwise you will get strange mails to the user account the cron job runs under. Modify your line to something like this:

Code:
0 8,17 * * * /usr/local/bin/myScript.sh 1>/dev/null 2>/dev/null

Corollary: you might ask yourself why i did not use "> /dev/null 2>&1". First, i find this easier to read. Second, this will do the same regardless of order, while "2>&1 > /dev/null" will not do the same when written this way or the other way round.

I hope this helps.

	   o   Paths for some default directories such as /dev (_PATH_DEV) and /tmp (_PATH_TMP) as well as paths for some miscellaneous utilities
