cdist-type__install_file - Man Page

Manage files with install command.

Description

This cdist type allows you to create files, remove files and set file attributes on the target.

If the file already exists on the target, then if it is a:

regular file, and state is:
present

replace it with the source file if they are not equal

exists

do nothing

symlink

replace it with the source file

directory

replace it with the source file

One exception is that when state is pre-exists, an error is raised if the file would have been created otherwise (e.g. it is not present or not a regular file).

In any case, make sure that the file attributes are as specified.

Required Parameters

None.

Optional Parameters

state

'present', 'absent', 'exists' or 'pre-exists', defaults to 'present' where:

present

the file is exactly the one from source

absent

the file does not exist

exists
