Some Bash tips

---

Search inside historic:

Ctrl-R: Lets do a history search.
Example:
Ctrl-R, then enter mkd
This will display the last mkdir commands launched.

Remind the last argument of previous command:

For that, you have to use: !$.
Example:
ls Scripts
cd !$
Will let you enter in the scripts directory.

Remind the last command:

Enter: !!

Specify to ask for confirmation before launching the Bash command:

shopt -s histverify
Then,
!ls
Display the contents of the last ls command. You just have to validate it to launch it.
