filesnip-cli

Extract line ranges, regex-matched lines, or delimited blocks from files. Zero dependencies.

Install

npm install -g filesnip-cli

Usage

Line ranges (1-indexed, inclusive)

filesnip app.js 10:25       # Lines 10–25
filesnip app.js 10:         # Line 10 to end of file
filesnip app.js :20         # Lines 1–20

Grep (regex match)

filesnip log.txt /ERROR/    # All lines containing "ERROR"

Block extraction

filesnip config.js /server/../}/   # From "server" to next "}"

Head / Tail

filesnip data.csv -n 5      # First 5 lines
filesnip data.csv +n 5      # Last 5 lines

Line numbers

filesnip app.js 10:25 -N    # With line numbers

Stdin

cat app.js | filesnip - 1:10

Why?

sed, awk, and head/tail work great — but the syntax is different on every platform. filesnip gives you one consistent, memorable interface that works everywhere Node.js runs.
