getopts(1) -- Command line options parser
SYNOPSIS
getopts options ...
DESCRIPTION
Getopts is a command line options parser for fish.
USAGE
Study the output of the following example
getopts -ab1 --foo=bar baz
a
b 1
foo bar
_ baz
The items on the left are the option flags. The items on the right are the option values. The underscore _
character is the default key for bare arguments.
Use read(1) to process the generated stream and switch(1) to match patterns
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,_
.
