Script not executing


I wasn't sure where to post this so I posted it here. I've used UNIX quite a bit, LINUX not so much. For some reason, my LINUX script will not execute if I type in the script name and press enter. I'm in the directory where the script is.

However, when I use ". ./" it executes fine. I was wondering why this is and what I need to do to have it execute at the command prompt without the ". ./".

. ./

This is part of a bigger question and issue I'm having which I'm not looking to resolve here. I'm trying to install Informatica 9.1 onto a LINUX RedHat platform. The install script wouldn't run when I typed in When I ran it with ". ./ a number of error messages popped up and the install hung. I'm working with Informatica Support on this.

Regards, Jim

Shouldn't that be


The reason your script won't execute as just is because the directory containing the script is not in $PATH . Your other system may have had . in $PATH (i.e. any current directory) which is a big security risk.

Thank you,

I didn't notice that this system when I did an "ls", did not have a '.' or a ".." directory. I do remember other systems I've worked on did have those directories. That certainly makes sense now.

. and .. definitely exist in Linux too, though ls may not show them. They have the usual meaning, current folder and previous folder.

You may be misunderstanding me about $PATH.

Try this command to show you the contents of the standard $PATH variable. It lists all the directories in order which the Operating System will search when looking for a program or executable script. If the variable $PATH contains . (current directory) then it will also look in whatever is the current directory.
echo "${PATH}"

The . and .. directories are always there.
ls -la

Thanks for the help again...
