command not found - error in exec() command

Question

I run this from php file

exec("epm package");

i got below error in error_log

sh: epm: command not found

I tested manually in terminal it works fine.

Answer 1

Try putting in a full path name:

exec("/path/to/epm package");

Your webserver process won't necessarily be set up with the same configuration as your own account.

Answer 2

sounds like epm isn't in the PATH environment variable for the user your webserver is running (probably apache). to solve this, do one of these:

• add the path to epm to the webserver-users PATH
• provide the full path for your command to be executed (/whatever/folder/epm package)
