Yet another linux CLI tips & tricks list (updated)

Yet another linux CLI tips & tricks list

(update: 2017-12-15 added few magic mc commands at bottom)

When I started my jurney with *nix like systems, the environment was hostile to me. But after a few years it become obvious that the CLI is a superior way of dealing with Linux OS. You can see a lot of similiar articles in the web like here or here but this list is stripped to what I find useful on the one hand, eliminating obvious on the other (eg. I'm assuming that you know you can browse hostory with arrow key or use tab for apt-get install completion).
So here is my list.

ctrl+r then type old-command-part - reverse search

Reverse search is one of the most important key shortcuts when using CLI, because usually you don't remember what exact arguments were used in in your beloved tricky_and_very_long_command you've commited in the past. You will find out that in the real life there is a limited number of commands (with minor modifications) your are using frequently.

ctrl+d leave or exit from console/ssh session etc

current line navigation commands

• ctrl+e go to end of line
• ctrl+a go to begining of line
• ctrl+u delete till begining of line
• ctrl+k delete till end of line
• ctrl+w delete word before cursor

NOTE you can change default bash editor to vi like editor with: set -o vi command

tmux

Allows executing commands on a detached console (useful when doing something via ssh and can't/won't have open session) - this should be a separate blog post but here is my cheat sheet

• tmux start a new tmux session
• tmux a or tmux attach attach to an existing tmux session

while in tmux session

• ctrl+b+d leave (d for detach) tmux session not killing it
• ctrl+b+c create a new pane
• ctrl+b+n next pane
• ctrl+b+p previous pane
• ctrl+b+" split pane horizontally
• ctrl+b+% split pane vertically
• ctrl+b+arrow go to: up right down left panel
• ctrl+b holding ctrl key and pressing one of arrow keys - allow change panel size!

NOTE: nice thing about tmux is...you can use tmux in tmux by doing double ctrl+b

mc - Midnight Commander

If you are old enough (like I am) you do remember famous Norton Commander or Total Commander. Midnight Commander is a similar tool - superior when it comes to copy files over ssh or ftp.
NOTE: if an escape key esc is not present int your keyboard - like in many bluetooth keyboards - you can use ctrl+[ instead.

• ctrl+\ - open favorite location list (then add current, edit, delete)
• esc+9 - open right pane menu
• esc+0 - exit
• esc+h - in any entry field (like 'open ftp/ssh' dialog window) wherever ^ character is present - opens current entry field history dialog
• alt + o - display dir under cursor on other pane
• alt + i - display current dir on other pane
• alt + . - display/hide hidden files
• alt + h - display history
• alt + y/u -  change dir to previous/next dir
