Top Forums UNIX for Dummies Questions & Answers Remove symlink and target Post 302947079 by rbatte1 on Monday 15th of June 2015 08:57:18 AM

I would worry that someone could create a link in error to something critical, e.g. You have a directory called /development and someone manages to chop off the end of their command
Code:
ln -s dev /dev

As someone who has moved /dev by accident, I can confirm that the results are rather difficult to deal with. We managed to follow the trace of our job and put it back, but you are looking to remove files.

I would be very wary of letting this run as a script.

Collect the details for sure, but let a human check them before taking action.


Just my thoughts,
Robin

symlink [start | stop | monitor | meta-data | validate-all] DESCRIPTION
This resource agent that manages a symbolic link (symlink). It is primarily intended to manage configuration files which should be enabled or disabled based on where the resource is running, such as cron job definitions and the like. SUPPORTED PARAMETERS

(required, string, no default) target Full path to the link target (the file or directory which the symlink points to). (required, string, no default) backup_suffix A suffix to append to any files that the resource agent moves out of the way because they clash with "link". .sp If this is unset (the default), then the resource agent will simply refuse to create a symlink if it clashes with an existing file. (optional, string, no default) SUPPORTED ACTIONS
This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 15. stop Stops the resource. Suggested minimum timeout: 15. monitor Performs a detailed status check. Suggested minimum timeout: 15. Suggested interval: 60. meta-data Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 10. EXAMPLE
