WANTED HELP IN SCRIPT writing
 
a script which will print "foo" when the input is "bar" and print "bar" when input is "foo"

If you'll be writing your script on a Linux system, bash would be a good candidate for your simple problem. I recommend taking the time to read:

If you run into problems, post what you've tried, and LQ members can offer suggestions.

There was another question, maybe a month or two back, that was very similar (it involved foo and bar, and a little extra complication...but then, so many questions seem to involve those two - foo and bar - that it isn't the easiest thing in the world to search on), so I wonder if maybe you and the other poster are at the same educational institution?

In any case, this being a program, you'll want to structure it, so you might want to start by posting the pseudocode you've come up with so far. You might not normally formally write pseudocode for a program this simple, but posting a flow chart would probably be a pain, and I'm not sure how else you'll be showing the rest of the world what you currently have in mind.

Per the LQ Rules, please do not post homework assignments verbatim. We're happy to assist if you have specific questions or have hit a stumbling point, however. Let us know what you've already tried and what references you have used (including class notes, books, and Google searches) and we'll do our best to help. Also, keep in mind that your instructor might also be an LQ member.

yes its actually a question.It was asked in the forum already and answered.Look up variable substitution and you'll be on the right track..

I'm not going to link to it at this time, but you're probably all thinking of the thread where I posted an unconventional solution to a very similar problem. ;) It wasn't foo and bar though, and the complication was that there was also a default value that needed to be printed if no input was given.

I don't think anyone ever actually posted a more conventional solution in that thread, but this is such a basic-level scripting problem that even a cursory reading of any scripting guide should be enough to solve it. :cool:
