I'll bet you're talking about doing this in your IDE, aren't you? If so, please be specific.

Well actually it is not a command line but web form. I have a form with 3 inputs,

1. search String

2. Replacement String

3. Test String

so there was a case how to replace / with tab in test string. I am not able to capture tab when I enter \t for replacement string and do replaceAll() on test string. I am definitely missing something here.

I do know that if I use "\t" in java program it works but how do we suppl that as argument as tab not as "\t" literal to command line?

You still don't get it. :-) "\t" or '\t' is java literal and it is not part of my code but need to be passed input to the program, may be it is from command line, or web form (and not from java program) :-)

Anyway I figured out a way for this, at least with web form with text field.

Type a tab in notepad and copy and paste it in text field of HTML form and there it works magically :-)
