Shell command
This component can expose regular shell commands as services. Services can be called from a script or in automation. Shell commands aren’t allowed for a camel-case naming, please use lowercase naming only and separate the names with underscores.
# 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 for arguments. When using templates, shell_command runs in a more secure environment which doesn’t allow any shell helpers like automatically expanding the home dir ~
or using pipe symbols to run multiple commands.
Any service data passed into the service call to activate the shell command will be available as a variable within the template.
