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)
|
||||
```
|
||||
|
||||
To view a short explanations of the flags in this plugin, type `extract` into your terminal after installation is completed.
