xdg-open FILE - opens a file with the default GUI app. I use it for example to open PDFs and PNG. I have a one letter alias for that. It can also open a file explorer in the current directory xdg-open . . Should work on any compliant desktop environment (gnome/kde).

Saving this thread for later, but I use rsync -a a lot.
cd then ls then cd then ls maybe Iโll throw a la -a
I use -A instead, which doesn't show "." and ".."
GNU Parallel
Going to shamelessly plug my custom bashrc setup which has a ton of little scripting helpers and a few useful aliases. Remember to clone recursively if you want to try it out. (Still very much a work in progress, but it's getting to be pretty robust)
clear because apparently I am too scatterbrained to comprehend more than one full page of text in the terminal
I almost never use clear because i'm afraid if i will need the text later.(just like infinity tab number on firefox)
Uhhh...sudo su
Don't be like me
sudo -i
qalc
I went a little overboard and wrote a one-liner to accurately answer this question
history|cut -d " " -f 5|sort|uniq -c|sort -nr|head -5
Note: history displays like this for me
20622 2023-02-18 16:41:23 ls
I don't know if that's because I set HISTTIMEFORMAT='%F %T ' in .bashrc, or if it's like that for everyone.
If it's different for you change -f 5 to target the command. Use -f 5-7 to include flags and arguments.
My top 5 (since last install)
2002 ls
1296 cd
455 hx
427 g
316 find
g is an alias for gitui. When I include flags and arguments most of the top commands are aliases, often shortcuts to a project directory.
Not to ramble, but after doing this I figured I should alias the longest, most-used commands (even aliasing ls to l could have saved 2002 keystrokes :P) So I wrote another one-liner to check for available single characters to alias with:
for c in a b c d e f g h i j k l m n o p q r s t u v w x y z; do [[ ! $(command -v $c) ]] && echo $c; done
In .bash_aliases I've added alias b='hx ${HOME}/.bash_aliases' to quickly edit aliases and alias r='source ${HOME}/.bashrc' to reload them.
Helix?
Yup! Migrated from VSCodium; wanted to learn a modal editor but didn't have the time or confidence to configure vim or neovim. It's been my go-to editor for 2+ years now.
I've been using vi (just the basics) for ~4 years, I don't think I could be arsed to pick up the keybindings the other way around lol. I've heard very good things about Helix, of course

Neofetch
let me guess, you either use arch or gentoo
tldr because I am too impatient to read through man pages or google the exact syntax for what I want to do.
There are exactly three kinds of manpages:
- Way too detailed
- Not nearly detailed enough
- There is no manpage
I will take 1 any day over 2 or 3. Sometimes I even need 1, so I'm grateful for them.
But holy goddamn is it awful when I just want to use a command for aguably its most common use case and the flag or option for that is lost in a crowd of 30 other switches or buried under some modal subcommand. grep helps if you already know the switch, which isn't always.
You could argue commands like this don't have "arguably most common usecases", so manpages should be completely neutral on singling out examples. But I think the existence of tl;dr is the counterargument.
Tangent complaint: I thought the Unix philosophy was "do one thing, and do it well"? Why then do so many of these shell commands have a billion options? Mostly /s but sometimes it's flustering.
tldr is the first of 4 ways I rtfm. Then -h, man, and then the arch wiki
i never use man at all. It's just too confusing.
Sudo !!
It reruns the last command as sudo.
Pretty useful since I'm always forgetting.

cd every single day.
You haven't discovered exa? Noob
/s
nano
du -sh /too/bar to get size of files/folders. sudo !! inserts sudo into previous command when forgotten. yay for full system update if yay is installed. cat reads files.
ncdu
qmv -f do ${dir}
... for quickly moving and renaming files. The default 'qmv' opens up your preferred text editor with a list of the source and destination name of the directory of files you want to move/rename. The '-f do' tells the command we only want to see/edit the [d]estination [o]nly. If you need to rename/move a bunch of files, it's much quicker to do it in vim (at least for me).

control+R
in bash, it lets you quickly search for previously executed commands.
its very useful and makes things much quicker, i recommend you give it a try.
Seems like an appropriate place to share https://github.com/agarrharr/awesome-cli-apps
I'm a fan of ripgrep and lsd in particular.
Big fan of lsd too.
But on a blotter
