noobient.file_changed

Synopsys

This role lets you detect changes in files between operations, so that you can indicate changes if, and only if, the file actually changed. This is useful when you do ad-hoc commands (command, shell, etc.) that cannot indicate if changes have been made or not.

Parameters

Name	Required	Example	Description
`path`	yes	`/etc/acme/foobar.com/foobar.com.cer`	File to check changes on.
`mode`	yes	`before`	Indicate whether the check is before or after the command(s). Possible values are `before` and `after`. If `before`, it calculates the checksum, if `after`, it checks the current checksum with the one calculated during the `before` run, and indicates the change if they differ.
`verbose`	no	`true`	If `true`, print more diagnostic messages. Defaults to `false`.
