# Meshtastic CLI Guide
The python pip package installs a "meshtastic" command line executable, which displays packets sent over the network as JSON and lets you see serial debugging information from the meshtastic devices. This command is not run inside of python, you run it from your operating system shell prompt directly. If when you type "meshtastic" it doesn't find the command and you are using Windows: Check that the python "scripts" directory is in your path.
## Optional Arguments
### -h or --help
Shows a help message that describes the arguments.
**Usage**
```shell
meshtastic -h
```
### --port PORT
The port the Meshtastic device is connected to, i.e. `/dev/ttyUSB0`, `/dev/cu.wchusbserial`, `COM4` etc. if unspecified, meshtastic will try to find it. Important to use when multiple devices are connected to ensure you call the command for the correct device.
**Usage**
```shell
meshtastic --port /dev/ttyUSB0 --info
meshtastic --port COM4 --info
