Hi All!
what's I user need to do when I try to run a scripts and get the following error:
sh: ./test.sh: Execute permission denied.

Make sure execute permission is set for the appropriate users. Depending on the script I usually set permission to 755 or 750 or 700.

Do a 'chmod u+x filename' so you can execute it yourself.

You do not have execution permission.

If you have write access to the file??

chmod 755 test.sh

...jcd...

chmod 777 test.sh should do it, but you may want to make it alittle more secure..755.

Hi
Without giving the execute permission for the script you can run it by

sh test.sh

If you have set the execute privileges for the file...I find that usually I forgot to make sure the directory(s) above the file has execute privileges too!

This is probably the error I make all too often....give the file 750 but gave the directory 760....

Regards,
Rita

I did not think the execute on a dir had anything to do with execution????

Without the x perm on a dir, you cant even cd to it.

...jcd...

Hello
Make sure to use the full path of the script you are trying to run. For example if I have a script in /home/richard/scripts
called script1
in the script I would put
/home/richard/scripts/script1
not just
./script1

As I have learned paths are very important.
Here is a past post of mine where I had the same problem.
I qoute Mr. A. CLay
This may not be all be you get the idea, remember the cron environment is intentionally very sparse and stupid; you have to tell it everything. It can barely spell cron on its own.

the absolute path must be specified

When creating cron jobs, it is very important to read the man page for cron where it talks about the environment. Bascially, it says you get almost nothing. cron does NOT login, it runs on the user's behalf but all those nice features like $PATH and other env setups will not take place. This is why the cron job runs fine when being tested from a login but fails when run by cron.

So good sysadmin practice for cron jobs is to write EVERY command with a leading / (also known as a full path as in /usr/bin/grep rather than just grep). This includes any references to files, and if one script calls another, every script involved must use full pathnames. Also, any special env setups (for example, Oracle) must be 'sourced' within the script.

Essentially, the cron job must explicitly setup everything that is done automatically by /etc/profile and .profile.

Hi All!

after set the rights, the script is running, but the root mail is receiving the msg sh: ./test.sh: Execute permission denied.
???

Is the full path in the cron script ?
Instead of ./test in your script do /home/whatever/scripts/test
and test has to have execute premissions.
Try chmod 777 test but this will make this script executable by everyone.

Hi
Instead of relative path use the absolute path for the script in cron.

Instead of ./test use //test
Use full path even for the commands in script test.

Also give execute permission for the script chmod 755 test.
Thanks.
Prashant.

I am not sure if this will help, but if the script is running OK you could add this to the command you running in crontab
> /dev/null 2>&1
This stops mail going to root.

Thanks
