How to use bck-i-search in your shell

There's a command I often use in my shell calling bck-i-search. It allows you to search in your history a command already executed in your shell.

You've got two ways:

• bck-i-search for back

• fwd-i-search for forth

Just use ctrl+r in your terminal and you'll open bck-i-search. Type a word and the command will find you one line. If you want to go deeper in history, use again ctrl-r and if you want to use the forth way, use ctrl-s.

Enjoy.
