# 🥾 walk

**Walk** — a terminal navigator.

Why another terminal navigator? I wanted something simple and minimalistic.
Something to help me with faster navigation in the filesystem; a `cd` and `ls`
replacement. So I build **walk**. It allows for quick navigation with fuzzy
searching, `cd` integration is quite simple. And you can open `vim` right from
the walk. That's it.

## Install

```
brew install walk
```

```
pkg_add walk
```

```
pacman -S walk
```

```
go install github.com/antonmedv/walk@latest
```

Or download [prebuild binaries](https://github.com/antonmedv/walk/releases).

Put the next function into the **.bashrc** or a similar config:

<table>
<tr>
<th> Bash/Zsh </th>
<th> Fish </th>
<th> PowerShell </th>
</tr>
<tr>
<td>

```bash
function lk {
cd "$(walk "$@")"
}
```

</td>
<td>

```fish
function lk
set loc (walk $argv); and cd $loc;
end
```

</td>
<td>

```powershell
function lk() {
cd $(walk $args)
}
```

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


Now use `lk` command to start walking.
