## ⬇️ Installation:

### Option 1 - Debian:
If you use a Debian OS go to [releases](https://github.com/theopfr/somo/releases) and download the latest .deb release.

### Option 2 - crates.io:
```sh
cargo install somo
```
Most of the time you will want to run this in ``sudo`` mode to see all processes and ports. By default, this is not possible when installed via cargo. But you can create a symlink so the binary can be run as root:
```sh
sudo ln -s ~/.cargo/bin/somo /usr/local/bin/somo
sudo somo   # this works now
```

### Option 3 - GitHub (Development Version):
*Warning:* This is the cutting-edge development version and may be unstable or contain incomplete features. You can install it via cargo directly from the GitHub repository.

```sh
cargo install --git https://github.com/theopfr/somo
```

### Option 4 - Nix (Development Version):
You can build and use the development version using Nix with Flakes.
```sh
nix build 'github:theopfr/somo?dir=nix'
sudo ./result/bin/somo
```

## 🏃‍♀️ Running somo:
To run somo just type: 
```sh
sudo somo
```

Somo supports the following features:

### ✨ Filtering:
You can use the following flags to filter based on different attributes:
| filter flag | description | value |
| :------------- |:------------- | :----- |
| ```--tcp, -t``` | filter by TCP connections | - |
| ```--udp, -u``` | filter by UDP connections  | - | 
| ```--proto``` | deprecated – use ``--tcp`` / ``--udp`` instead | ``tcp`` or ``udp`` | 
| ```--port, -p``` | filter by a local port | port number, e.g ``5433`` |
| ```--remote-port``` | filter by a remote port | port number, e.g ``443`` |
| ```--ip``` | filter by a remote IP | IP address e.g ``0.0.0.0`` |
| ```--program``` | filter by a client program | program name e.g ``chrome`` |
| ```--pid``` | filter by a PID | PID number, e.g ``10000`` |
| ```--open, -o``` | filter by open connections | - |
| ```--listen, -l``` | filter by listening connections | - |
| ```--exclude-ipv6``` | don't list IPv6 connections | - |

### ✨ Compact table view:
To get a smaller, more compact table use the ``--compact, -c`` flag.

### ✨ Process killing:
With the ``--kill, -k`` flag you can choose to kill a process after inspecting the connections using an interactive selection option.

### ✨ JSON and custom output format:
Using the ``--json`` flag you can choose to retrieve the connection data in JSON format. <br />
You can also define a custom output format using the ``--format`` flag, for example:
```sh
somo --format "PID: {{pid}}, Protocol: {{proto}}, Remote Address: {{remote_address}}" # attributes must be specified in snake_case
```
In the format-string, the attributes have to be specified in *snake_case*.

### ✨ Sorting by columns:
The ``--sort, -s`` flag can be used to sort the table after a specific column ascending. For example:
```sh
somo --sort pid   # column names must be specified in snake_case
```
To get a descending order, you can use the ``--reverse, -r`` flag.

echo 'autoload -U compinit && compinit' >> ~/.zshrc
```

#### Fish
```fish
mkdir -p ~/.config/fish/completions
somo generate-completions fish > ~/.config/fish/completions/somo.fish
