Obviously something is wrong....

You can check file permissions. Maybe your script has no access to /tmp. Please post the output of the following commands:

Code:
ls -ld /
ls -la /tmp

Maybe you typed in my command not 100% exact as I typed it here? I suggest you to double check it and copy&paste it here in. Maybe there's error.
Please always use code tags for code, input files, or command output. That's this icon: Image

...and as a very likely issue that will be present here: please use absolute path names! Instead of this...

Code:
shell_exec('at -f phpsc.sh now + 5 minute >/tmp/log.txt 2>&1');

...use this...
Code:
 shell_exec('/usr/bin/at -f /path/to/your/script/phpsc.sh now + 5 minute >/tmp/log.txt 2>&1');

Have a look at your php.ini too. Especially at the setting disable_functions. Maybe shell_exec is listed there?

from php (shell_exec):
Code:
You do not have permission to use at.
