@cR0w@infosec.exchange Another one:
Let's say that you sometimes have to paste sensitive things into your terminal, like login strings, or credentials.
If you paste them in normally, they'll show up in your history, and that could be bad. That can be mitigated to some extent in Bourne shell with:
export HISTCONTROL=ignorespace
Now, you can put a leading space in front of your sensitive command and it won't show up in your history:
curl -u username:password https://www.example.com/login
(put in backticks to make it obvious there's a leading space)
