SEN - Stream Editor for N00bs (or Normal people)

SEN is a simple stream editor with limited features. It was designed to work with other tools through UNIX pipes. Ex find, grep, rp, xargs, etc.

Right now there are only four operations:

• Replace matching pattern.
• Add a line to a specific line number.
• Remove line matching pattern.
• Remove lines by number.

Install

Sen is installed via npm:

npm install -g sen-cli

Usage

Usage: sen [options] [command]

It can be used with file arguments.

Add:

cat filename.py | sen add '# My awesome comment' 1

It can be used with stdin.

find . | xargs sen remove -i .bak '# My awesome comment'
