# extract plugin
|
||||
|
||||
This plugin defines a function called `extract` that extracts the archive file
|
||||
you pass it, and it supports a wide variety of archive filetypes.
|
||||
|
||||
This way you don't have to know what specific command extracts a file, you just
|
||||
do `extract <filename>` and the function takes care of the rest.
|
||||
|
||||
To use it, add `extract` to the plugins array in your zshrc file:
|
||||
|
||||
```zsh
|
||||
plugins=(... extract)
|
||||
```
|
||||
|
||||
