# iptables -S | sorted | colored

Sort and color the output of `iptables --list-rules`

![Sorted and colored output](iptables_sorted_colored.png)

## implementation

### iptsort

- download the [bash script](iptsort) in `/usr/local/bin/`

- after verification, make it executable with `chmod +x /usr/local/bin/iptsort`

- try it with `iptables -S | iptsort`.

### bat

- install (or download it in `/usr/local/bin/` if not available for your distribution) the excellent [bat](https://github.com/sharkdp/bat)

- build the necessary tree structure with `mkdir -p ~/.cache/bat/ ~/.config/bat/syntaxes/`

- download the [lexer](iptables.sublime-syntax) in `~/.config/bat/syntaxes/`

- rebuild the bat cache with `bat cache --build`

- try it with `iptables -S | bat`.

**that's all !**

you can now orchestrate the whole thing with `iptables -S | iptsort | bat`.

## trick

 you can add this helper in your `~/.bashrc` script :

 

```bash

function iptables {

  org=$( which iptables ) || return;

  if [ "${1}" ]

  then

    "${org}" $@

  else

    "${org}" -S | iptsort | bat -p

  fi

}

```

this following helper can also be very useful :

```bash

function ss {

  org=$( which ss ) || return;

  if [ "${1}" ]

  then

    "${org}" $@

  else

    "${org}" -plntu | sed -e 1d -e 's/users:(//g' -e 's/)$//g' | awk '{print $1, $5, $7}' | column -t | bat -pl c

  fi

}

```

the lexer was partially written using [Iro](https://eeyo.io/iro/).
