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.
