I need to swap out local Maven repositories for the project I'm working on. I created a symbolic link, "maven_repo" in my home directory that points the current local Maven repo. When it came time to change the "maven_repo" link I realized that changing a symbolic link to a directory requires an extra command :
ln -sfn DESTINATION_DIRECTORY LINK_NAME
It wasn't so obvious from the man page. This blog post saved me a ton of time.
