Hello, I have a file a.txt with lines of commands I want to run, say: echo 1 echo 2 echo 3 If I was on csh (unix), I would have done source a.txt and it would run.

In a linux shell, is it possible to return the output of the last command. I realize I could have piped it or sent the output to a file, but my requirement is to retrieve that output after the command has been run. Using csh, but would hear about any shell.

So, can anyone tell me a nice and clean way to get this to evaluate this when I invoke...

I am fairly inexperienced with shell(csh in this case) scripts but was asked to edit one. I was asked to add a config file to make it much simpler to edit several specific variables.
