repx

Python regular expression file transformer.

If you know sed or awk – or even vim's search & replace functionality, repx should feel familiar, but simpler and easier to use.

Usage

By default repx will take input from standard in and output the transformed text to standard out

$ echo 'Hello World!' | repx /World/Universe/
Hello Universe

File input and output is of course also supported

$ cat in.txt
I like command line tools!
$ repx /like/love/ in.txt -o out.txt
$ cat out.txt
I love command line tools!

Files can be transformed in-place (use -f or --force to skip the confirmation)

$ repx -p /like/love/ in.txt
Do you really want to replace the contents of `in.txt`,
-- the content will permanently and irrevocably be changed!
Type `in.txt` to replace the file: in.txt (user input)
$ cat in.txt
I love command line tools!
