# LASH (Local Area Share HTTP) # LASH (Local Area Share HTTP)
## Usage
Using lash is pretty simple. You just provide any amount of command line
arguments and it will generate a share link, and a code. You either go-to
http://<your-local-ip>:port or goto http://<your-share-link> to access the
files.
## Building from Source
Lash only has one dependency and that it is Go >= 1.26.3. To build it you just
run either of the two following commands.
```sh
$ make
```
or
```sh
$ go build -o lash ./bin/main.go
```
