# nav
Terminal navigator for interactive `ls` workflows.

![alt text](https://raw.githubusercontent.com/dkaslovsky/nav/main/examples/nav_example.png)

<br/>

## Overview

`nav` is a terminal filesystem explorer built for interactive `ls` workflows.
It can be used as a standalone TUI or in bash/zsh functions such as

```bash
# interactive ls + cd
function nv {
	cd "$(nav --pipe "$@")"
}
```

</td>
<td>

```bash
# interactive ls + clipboard
function nvcp {
	nav --pipe "$@" | pbcopy
}
```

</td>

<td>

```bash
# interactive ls + multi cat
function nvcat {
	nav --pipe "$@" | xargs cat
}
```

</td>
</tr>
</table>

`nav` is intended to be an interactive replacement for `ls` and currently supports some of the most common `ls` options:
<table>

long list with full details

</td>

<td>

`ls -l`

</td>

<td>

`nav --list` / `nav -l`

</td>
</tr>

show hidden files

</td>
<td>

`ls -a`

</td>

<td>

`nav --hidden` / `nav -a`

</td>
</tr>

follow symlinks

</td>

<td>

`nav --follow` / `nav -f`

</td>
</tr>

</table>

These options are available as interactive toggles and can also be invoked on start with the appropriate command line flag ([see below](#full-list-of-commands)).

Human readable file sizes (`ls -lh`), color output (`ls --color`), and a custom sort order are on by default and cannot currently be configured.

In the future, `nav` might support a wider range of `ls` options and configuration.
