search and replace tools in linux

Question

What are the best search and replace tools in linux?

I want to find an easy way.

Thanks

Answer 1

You can use rpl .

It will replace strings with new strings in multiple text files. It can work recursively over directories and supports limiting the search to specific file suffixes.

rpl [-iwRspfdtx [-q|-v]] <old_str> <new_str> <target_file(s)> 

Answer 2

find for finding files/directories

grep or ack [1] for searching files

sed for search/replace in files

awk and cut for slicing/dicing text

for anything non-trivial I usually reach for perl
