<div>Yes, I have seen it before, now you mention it. Seems my old windows machines always started with PATH=.;... Or at least I seem to remember it that way. Regardless, I always *assumed* the computer always looked in the current directory first.<br></div>
<div> </div>
<div>Anyway, as you saw in previous email i am now getting this<br></div>
<div>[root@vslaw2 ~]# ./server_setup.sh<br></div>
<div>-bash: ./server_setup.sh: /bin/bash^M: bad interpreter: No such file or directory<br></div>
<div>error.<br></div>
<div> </div>
<div>No idea what the ^M means. I don't see anything when looking at the file in nano and confirmed it with VI/VIM just to be sure, with same result<br></div>

<div>UNIX looks for binaries and scripts in your PATH (echo $PATH). Since . isn't in your path, you need to provide the path to the command you're trying to run. You've almost certainly seen this syntax before - the most common way is to be in the directory where the script lives, and use ./ (dot slash) like so:<br></div>
<div> </div>
<div>./server_setup.sh<br></div>
<div> </div>
<div>. means the same thing it does in DOS/Windows - refers to the current working directory.<br></div>
<div> </div>
<div>Note - I've never seen anyone put . in their UNIX path and I wouldn't recommend it. IIRC the reason behind this -- it ensures that when you run (for example) visudo, you're getting the real /usr/sbin/visudo and not a rogue binary in whatever the current directory happens to be. /usr/sbin tends to be more secured from tampering than some other random directory on the filesystem where you might be while trying to execute visudo (again, visudo is just an example) from.<br></div>
