read-signal

The read-signal will run the then commands if the signal name is reached or the else commands if the signal is not yet reached.

- read-signal: ready
  then:
  - sh: this.sh
  else:
  - sh: that.sh

The read-signal command can also be created with YAML mapping but 'name' is the only argument.

- read-signal:
    name: ready
  then:
  - sh: this.sh
  else:
  - sh: that.sh
