I'm a new-be in Linux I want to be able to update/overwrite all files named 'test.txt' in a directory(and its subdirectory) with a particular text, say 'information'. The files named test must be searched recursively within the directory as they may be present in any of the sub-directories. Would be glad if anyone tell me a command for this. Thanks and Regards

There is not one command. You would need to use various commands either in a script(batch file) or on a single line that takes the output from one function to the input of the next. There are many ways to do it. They all would involve some form of what you asked it to do. Search files by name, recursive. (some people put files listed in a new file to use as second part of input) Take those files and search for text string. Replace string with new string.. See the man pages on functions and put together a plan. I think you can do it. I read it wrong and answer it wrong too. So get off my case you peanut.
