!! is the same as !-1
But you can also do
!-2!-3!-4

AI 🤖 is getting so good..
You can’t trust anything you see on the Internet.
You have to think critically about all the information and always be skeptical.
You know, what we should have ALWAYS BEEN DOING; since time immemorial!
😁
If you’re changing the user & group ownership to the SAME person..
You can streamline it from 2 commands:
chown ray /var/tmpFile
chgrp ray /var/tmpFile
To 1 command, only typing the username once:
chown ray: /var/tmpFile
Using TMUX but can’t scroll your output? This video is for you!
Here we introduce TMUX’s Copy Mode.
Copy Mode is how you
# Display current value for option 'mode-keys'
show-options -g mode-keys
# Set to vi-style key bindings
set-option -g mode-keys vi
# Set to emacs-style key bindings
set-option -g mode-keys emacs
# Set key binding mode to vi OR emacs
set-option -g mode-keys vi
set-option -g mode-keys emacs
# List emacs key bindings
list-keys -T copy-mode C-r
list-keys -T copy-mode C-s
# List Vi key bindings
list-keys -T copy-mode-vi ?
list-keys -T copy-mode-vi /
list-keys -T copy-mode-vi L
list-keys -T copy-mode-vi M
list-keys -T copy-mode-vi H
# Redefine Vi searching
bind-key -T copy-mode-vi ? command-prompt -i -I "#{pane_search_string}" -p "(search up)" "send -X search-backward-incremental \"%%%\""
bind-key -T copy-mode-vi / command-prompt -i -I "#{pane_search_string}" -p "(search down)" "send -X search-forward-incremental \"%%%\""
# Redefine Emacs commands:
# bottom-line
# middle-line and
# top-line
bind-key -T copy-mode L send-keys -X bottom-line
bind-key -T copy-mode M send-keys -X bottom-line
bind-key -T copy-mode H send-keys -X bottom-line
Are you new to Vim but every time you launch it..
Exiting feels like trying to escape a blackhole! 🌌🚀
I just launched my Vim Crash Course and it will show you how to edit files, never get lost, and exit once and for all. 😌
