How can I Modify Variables inside a txt file?

Question

Im looking for a way to change variables inside a text file? for instance I have a Install.iss file. Inside the ISS file is a variable I put in called %COMPNAME% and another called %WORKGROUP%. Is there a way to run a program or script against this file and read the system variables and do a search replace? I also want to use this on several other text files. Thanks.

Answer 1

"sed" is what you are looking for. It is included in almost every unix/linux dists or you can download it:

I would use Apache's ANT tool to make this happen.

Creating ANT build files is similar to a script of another kind, except it is build using XML and pre-defined tag sets. They have a standard function for finding and replacing values within text files. Check out the Replace task.

It's a very powerful tool once you learn everything it can do.
