getopts(1) -- Command line options parser

SYNOPSIS

getopts options ...

DESCRIPTION

Getopts is a command line options parser for fish.

USAGE

Study the output of getopts in the following example

getopts -ab1 --foo=bar baz

a
b    1
foo  bar
_    baz

The items on the left are the command option keys. The items on the right are the option values. The underscore _ character is the default key for bare arguments.

getopts -ab1 --foo=bar baz | while read -l key option
    switch $key
        case _
        case a
        case b
        case foo
    end
end

NOTES

  • A double dash, --, marks the end of options. Arguments after this sequence are placed in the default underscore key, _.
