Just installed mint yesterday, I get it now

I thought it'd be a pain but installing programs through the terminal is actually so nice, I never would have expected it

tab completion works in more places than you might expect

ctrl-a/ctrl-e for start/end of line

ctrl-u to clear the command you’ve typed so far but store it into a temporary pastebuffer

ctrl-y to paste the ctrl-u’d command

ctrl-w to delete by word (I prefer binding to alt-backspace though)

ctrl-r to search your command history

alt-b/alt-f to move cursor back/forwards by word

!! is shorthand for the previous run command; handy for sudo !!

!$ is the last argument of the previous command; useful more often than you’d think

which foo tells you where the foo program is located

ls -la

cd without any args takes you to your home dir

cd - takes you to your previous dir

~ is a shorthand for your home dir
- Saved! Thank you so much.
  
  I've used Linux full-time since late 2020 and I never knew about ctrl+y and ctrl+u.
  
  I'd also like to contribute some knowledge.
  
  aliases
  
  You can put these into your ~/.bashrc or ~/.zshrc or whatever shell you use.
  
  ### ### ls aliases ### # ls = colors alias ls='ls --color=auto' # ll = ls + human readable file sizes alias ll='ls -lh --color=auto' # lla = ll + show hidden files and folders alias lla='ls -lah --color=auto' ### ### other aliases ### # set color for different commands alias diff='diff --color=auto' alias grep='grep --color=auto' alias ip='ip --color=auto' # my favourite way of navigating to a far-off folder # this scans my home folder and presents me with a list of # fuzzy-searchable folders # you need fzf and fd installed for this alias to work alias cdd='cd "$(sudo fd -t d . ${HOME} | fzf)"'
  
  recommendations
  
  ncdu - a shell-based tool to analyze disk usage, think GNOME's baobab or KDE's filelight but in the terminal
  
  zellij - tmux but easy and with nice colors
  
  atuin - shell history but good, fuzzy-searchable. If you still have the basic shell history (when pressing ctrl+r), I cannot recommend this enough.
  
  ranger - a terminal file-browser (does everything I need and way more)
- Saving this! Absolutely gold, thanks for writing it up. You're what makes the Linux community cool. ❤️
  
  tab completion works in more places than you might expect
  
  I've found tab to be such a nice "please give me a hint" button.
  
  Bonus tip : Sometimes you won't get auto complete because there's too many possibilities and the computer can't be certain which one you want. Hitting tab multiple times will show the possibilities, so you can type in enough characters to remove ambiguity, hit tab again, and boom auto complete!
  
  ...That was a terribly convoluted explanation I'm sorry. Just try hitting tab multiple times for fun if you're stuck it's kinda handy. Lol
- If you’re looking for a full list of these kind of navigation shortcuts, they all come from readline so read the man page for that. Or just look up the basic navigation of emacs which is what readline is mimicking.
  
  A neat thing is that a lot of command line programs use readline. So learning and configuring it will also be useful in for example the Python REPL and calc.
  
  Here are some neat configuration options you can put in ~/.inputrc
  
  set completion-ignore-case on set show-all-if-ambiguous on set completion-prefix-display-length 9 set blink-matching-paren on set mark-symlinked-directories on
  
  And if you are a sensible person who is used to vim
  
  set editing-mode vi set show-mode-in-prompt on
- I've been using the commandline for so long but was always too lazy to look up the rest of these commands after ctrl+a/e and ctrl+r THANK YOU!!!
  
  post this commend again and again! There's always lazy idiots like me who will be helped that way!
- Makes me realize just how illogical and bad these shortcuts are
  
  I believe, these are Emacs shortcuts. There's also set -o vi in bash, but I've never used it, so can't vouch for it.
  
  That’s good to know. It’s interesting that the other commenter thinks emacs shortcuts are illogical. I’ll make my best guesses at the logic
  
  ctrl-a/ctrl-e for start/end of line
  
  a is the beginning of the alphabet; e for end (of line)
  
  ctrl-u to clear the command you’ve typed so far but store it into a temporary pastebuffer
  
  ctrl-y to paste the ctrl-u’d command
  
  No idea here. Seems similar to nano with k-“cut” and u-”uncut”.
  
  ctrl-w to delete by word
  
  w for word obviously.
  
  ctrl-r to search your command history
  
  alt-b/alt-f to move cursor back/forwards by word
  
  r reverse, b back, f forward. Not sure why alt vs control though; presumably ctrl+b and ctrl+f do different things although I know emacs likes to use Alt (“Meta”) a lot.
  
  In the 1980s, Digital Equipment Corporation had a word processor, WPS. Ctrl-u cleared the line you were typing and put it into the paste buffer. Maybe legacy usage?
  
  Explains why they are so illogical! Unfortunately i think its better to just learn the defaults since i remote into lots of servers where i dont carry my config
- alt-. also pastes the last argument of the previous command (useful if you need to modify it a bit)
  
  instead of any shortcuts starting with "alt" you can also press "esc" followed by the second key, e.g. pressing "esc", releasing it and then "a" is the same as pressing "alt-a" (useful if you have only one hand available, or if alt is not availalble)
  
  if you put a space before a command, it will not be saved in history (useful sometimes, e.g. if you pass a password directly as an argument)
- Nice list, TIL about Ctrl+U and Ctrl+Y.
  
  If I may add, Ctrl+X into Ctrl+E opens $EDITOR to edit the current line.
