# Example: Via CLI
Uses RCM through the `rcm` command-line tool.
## Usage
```sh
# Dry run — show what would change, make no changes
rcm config.rb --dry
# Verbose output
rcm config.rb --debug
# Limit execution to specific hosts
rcm config.rb --hosts earth,mars
# Apply configuration
rcm config.rb
```
## What it does
- Creates `/tmp/example/hello.txt` with static content (parent directory created automatically)
- Creates `/tmp/example/info.txt` from an inline ERB template containing the hostname and current date
Both operations only run when the current hostname is `earth`.
