The idea command. I read about this a few days back and found it really interesting.
Many times we want to jot down some ideas, notes etc while working. It would be awesome if we could just type idea into terminal and start taking notes. Here is how to do it :
touch ~/.ideas.mdbash_profile to open it quickly - alias idea="vim ~/.ideas.md"idea in terminal. Now I use this setup actively whenever I need to note down something.
