Creating a directory that is a union of several directories can be achieved with a few symlinks at the command line.

Here is how I am creating a virtual directory of all my projects that is a combination of both work and not-work projects. I am creating symlinks for every directory under ~/work and ~/git.

rm -rf ~/projects mkdir ~/projects ln -sf ~/work/* ~/projects ln -sf ~/git/* ~/projects

⚠ Notice that first I am recreating the directory each time. This will ensure that any project that is deleted from their actual directory is removed from the virtual gallery.

Bash is a language that is quite useful for automation no matter what language you write in. Bash can do so many powerful system-level tasks. Even if you are on windows these days you are likely to come across bash inside a cloud VM, Continuous Integration, or even inside of docker.

I have three techniques that help me write more composable bash scripts.
