 * `pip_unknown_command` – fixes wrong `pip` commands, for example `pip instatl/pip install`;
 * `php_s` – replaces `-s` by `-S` when trying to run a local php server;
 * `port_already_in_use` – kills process that bound port;

 * `python_command` – prepends `python` when you trying to run not executable/without `./` python script;

 * `quotation_marks` – fixes uneven usage of `'` and `"` when containing args';
