[CentOS] bash file direct execution

Hi all.

I have a little strange problem. I created a file called 'test.sh' in the root directory containing: #!/bin/sh echo test

When I execute it with '/test.sh' there is no output. When I source it by executing it with '. /test.sh' the output comes ok. When I move it to '/root' and execute it with '/root/test.sh' then it works perfectly. When I move it to '/home' and execute it with '/home/test.sh' there is no output.

Could someone tell me what I shoud do to make the script run without sourcing it with '.' ? This problem happens only on one CentOS 4 box I have, on the others it works perfectly. What am I doing wrong ? The permissions are 755 on the file itself, and I execute them logged as root.

Thanks, Daniel
