rmline is a quick n' dirty tool that rewrites a given file, removing the given line
or range of lines, and outputs the removed lines to stdout.
rmline may not handle large files very well as the entire file is loaded into memory
and the entire file is rewritten. No attempts at optimatization have been made; just
a quick tool good enough for my use cases. Contributions are welcome.
Place rmline into your path. Requires PHP.
rmline <filename> <line number> [ending line number]
