} ${extract{5}{:}{<line>}}
} extracts the fifth colon-separated field, while
} ${extract{uid}{<line>}}
} extracts the field keyed by uid= in the line. What do you think?
} I'm not sure that I like numbering the first field from zero. It is
} sure to cause confusion, because people will talk about things like
} "the 6th field in the password file". I'd rather number from 1 and
} give an error for zero (or give the whole line, like $0 after a regex
} match).
I'm happy with both of these comments, with the provisio that if we
overload extract (which makes some degree of sense) are we going to get
confusion among users??
