This component can expose regular shell commands as services. Services can be called from a script or in automation.

# Example configuration.yaml entry
# Exposes service shell_command.restart_pow
shell_command:
  restart_pow: touch ~/.pow/restart.txt

Configuration variables:

• Alias for the command
• Command itself.

The commands can be dynamic, using templates to insert values of other entities. For example

# Apply value of a GUI slider to the shell_command
input_slider:
  ac_temperature:
    name: A/C Setting
    initial: 24
    min: 18
    max: 32
    step: 1
{% raw %}
shell_command:
  set_ac_to_slider: 'irsend SEND_ONCE DELONGHI AC_{{ states.input_slider.ac_temperature.state}}_AUTO'
{% endraw %}
