getopts(1) -- Command line options parser
|
|
=========================================
|
|
|
|
## SYNOPSIS
|
|
|
|
getopts *options* ...<br>
|
|
|
|
## 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, `_`.
