# Overwatch

Raku Overwatch can be used to restart programs when they crash or 
when files are modified.

```
overwatch [options] <program> [<program arguments>]
```

```
<program>
```
    
A program/script name is required.

-e=<executable> | --execute=<executable>
```

Default: ```raku```

The executable that runs the specified <program>.

### Keep Alive

```
-k | --keep-alive
```

Default: ```True```

Automatically rerun the program.
 

### Exit on error

```
-x | --exit-on-error
```

Default: ```False```

Stop overwatch if the <program> exited with a non-zero code.

### Git

```
-g | --git

Default: ```0```

Checks default upstream git repository and pulls if local is behind.

A value of zero or less disables this option.
