Before getting to the topic, I wanted to mention how much more I like the old Reddit. The new one is heavy and really cumbersome to use. I was browsing through Reddit using the old interface, and noticed this post, which mentioned that adding a space before a command prevents it from being written to history.
Decided to give it a shot. I opened a terminal and typed "hello". Checked ~/.bash_history, and sure enough, at the end of the file there was "hello".
Then I typed " pwd" (note the space prepended), and the command was not added to the Bash history file. HISTCONTROL even allows avoiding duplicates.
Why aren't these taught in college?
