# Utility

Defines general aliases and functions.

**Note:** Some of the utilities configured in this module might be provided via
GNU utilities with incompatible arguments on non-GNU systems. In such cases,
using [*`gnu-utility`*][1] module is recommended and it must be loaded
**before** this module.

## Settings

### Highlighting

If you have enabled color globally in *~/.zpreztorc*, you may disable it for
certain commands.

To disable `ls` color, add the following line to *~/.zpreztorc*; when coloring
is disabled, type indicators (`\*`, `/`, `=>`, `@`, `=`, `|`, `%`) will be
appended to entries.

```sh
zstyle ':prezto:module:utility:ls' color 'no'
```

To disable GNU coreutils `ls` to list directories grouped first, add the
following line to *~/.zpreztorc*:

```sh
zstyle ':prezto:module:utility:ls' dirs-first 'no'
```

To disable `diff` highlighting, add the following line to *~/.zpreztorc*:

```sh
zstyle ':prezto:module:utility:diff' color 'no'
```

To disable `wdiff` highlighting, add the following line to *~/.zpreztorc*:

```sh
zstyle ':prezto:module:utility:wdiff' color 'no'
```

To disable `make` highlighting, add the following line to *~/.zpreztorc*:

```sh
zstyle ':prezto:module:utility:make' color 'no'
```
