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]


Options:

-V, --version  output the version number
-h, --help     output usage information


Commands:

replace <toReplace> <replacer> <file>  Replace pattern throughout the stream.

Examples

Replace:

sen replace 'import.*Package' 'import NewPackage' filename.py filename2.py

It can be used with file arguments.

Add:

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

It can be used with stdin.

Remove:

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

-i can be used to generate backup files.

Remove lines:

sen removelines -i 1,2,3 ~/.ssh/known_hosts

-i without arguments edits the file in place.
