cut(1) is a small shell utility, part of the
indispensible Unix (or GNU) tool chain. It is
located in the coreutils package, assuming
a Debian system or fork.
cut is used for simple but effective parsings
of command outputs, for example this one
#! /bin/zsh
key () {
local key=$1
ascii -t $key | head -n 1 | tr -s " " | cut -d" " -f 2
}
You can get the source with
$ apt-get source coreutils
The cut source will then be in the src/ dir, in
the file cut.c .
cut.c is 832 lines of very good-looking C,
which isn't always the case if someone was
under that illusion.
