Who hasn't written some read-only magical Bash voodoo, only to find you need to decrypt your own creation later on? Luckily, Explain Shell can help with that. Here's an example from my .bash_history file:

Bonus II: It's a good thing they wrote "shell" in a different color. I was wondering why I had "explains hell" in my bookmarks.
