awaitchange

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

Usage

Usage: awaitchange [OPTIONS] [FILES]...

Arguments:
  [FILES]...  Files to be watched

Options:
  -r <CHECKRATE>     How many times per second files should get checked for updates [default: 2]
  -e, --exec <EXEC>  Command to be executed on filechange. If unset, awaitchange simply exits on filechange and yields controll to the programm next in line. The symbol {} can be used and will be replaced by the name of the file that has changed upon execution
  -h, --help         Print help

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:

    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 --exec flag an pass a script, that should be executed (in sh)

awaitchange deployment.yaml --exec 'kubectl apply -f {}'
