# awaitchange

Command line tool that does little, is easy to use and helps a lot!

## Usage

```
awaitchange 0.3.0

USAGE:
    awaitchange [OPTIONS] [watch]...

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -r <checkrate>        How many times per second files should get checked for updates [default: 2]
        --do <command>    Command to be executed on filechange. If unset, awaitchange simply exits on filechange and
                          yields controll to the programm next in line

ARGS:
    <watch>...    Files to be watched

```

## Example

lets say you want to update your kubernetes objects, every time you changed your deployment or service config,
you'd use awaitchange like this:
```sh
    while [ true ]
    do
        clear       # Clear terminal window
        kubectl apply -f deployment.yaml
        kubectl apply -f service.yaml

        awaitchange deployment.yaml service.yaml
    done
```

There is a shorthand for this, just use the `--do` flag an pass a script, that should be executed (in `sh`)

```sh
awaitchange deployment.yaml --do "kubectl apply -f deployment.yaml"
```
