I am not able to execute a multiple sed statement using pipe filters in a variable. i am trying to extract a path from a file and then working on that path to change a few letters within the path by going through another sed statement.

the code looks like this:

i saved this file in stest.sh. When i run the file, nothing happens. I ahve to press Ctrl+C to exit back to the command prompt.

Let me also provide the path.cfg file:

Well, your immediate problem is that echo is not a command that can accept input from stdin, so you can't use it in the middle of a pipe chain like that. Oh, and there's an embedded wc command without any input following that echo.


I see a couple of other errors and weak points, such as the "&j" in grep (I think you want "$j"), that you could probably combine the two sed commands into one, and that $(..) is highly recommended over `..`. Also, your code would be much easier to read and debug if you'd use a decent indentation scheme*. But I'm too tired right now to go into any more detail.


*Edit: I just noticed you're using quote tags instead of the proper [code][/code] tags. quote tags don't preserve formatting the way code tags do. So apologies if your code originally had indentations.

I would add to David's post and say if you also provide the desired output from your chosen input that it may help someone see where we may be able to help?
