I have a .sh file, which I need to run daily. I placed it in /etc/cron.daily
But it was not running. Is any other I need to do?
Thanks

| Posted by akasharya, 09-08-2010, 03:56 AM | | Is your script working when runs manually? did you check the permission of the script? whats showing in your log file? try to put this script on some different machine and see if it works or not.

|
| Posted by srinidhi95, 09-08-2010, 12:17 PM | | Yes, Its running when tried manually.
There is no trace in log file for that .sh file that I placed inside the /etc/corn.daily. All other crons of my users are running perfectly.

| Posted by srinidhi95, 09-08-2010, 12:19 PM | | Yes, cron deamon is running. All the crons of my users are running

| Posted by srinidhi95, 09-08-2010, 12:21 PM | | The sh file is written the way to send mail if started to run and the log of the process at the end. But Im not getting the mail. So Im sure that It was not running.

| Posted by akasharya, 09-09-2010, 03:26 AM | | I hope your script file's name is not starting with .script or something like that. By the way is this redhat like OS or debian like OS?

| Posted by mugo, 09-11-2010, 05:00 AM | | Check the dumb things...make sure the user actually running the cron (is it root, or a shell user?) has executable (x) permission. An instance where it would run for you, but not cron because of executable perms -
-rw-r-xr-x root.myuser scriptfile.sh
If you are "myuser", and execute it will run (myuser has x), if you are putting your cron entry under root user, then it doesn't have --x for root. Most ppl think of root as being able to do anything no matter what, but if root is the owner, and doesn't have at least --x on a file, it simply won't execute.
Another little trick I use, instead of editing or placing files directly in cron, I create a "cronfile" with all the cron commands I want to run. If I add or change, you simply do a
crontab -r
then
crontab /path/to/cronfile
and it loads up your cron jobs, each with your time fields and commands.
You then have one place to look and control things from, very easy to get a handle on your scheduled crons as a whole.
