I think I got polluted by my own ecosystem and do not have a sane workflow like Yuno but....

I rarely do "ls": I use tab to show the list of files, and disable bash specific completion (so that it shows the files even when it expects only directories).

I rarely do "cd": I run most things from some project directory, and I have "cd ~/zephyrproject/zephyr" in ~/.bashrc for whichever project I work on.

1. "xrun" - (which I bound to a keybinding: a script to open a new https://tools.suckless.org/tabbed/ terminal, with an initial command that spawn at every new tab, or if a tabbed window is focused, spawn the command as a tab *inside* the focused window)

2. "$clientname" - (which is an alias to something like "xrun sudo -s -u $clientname" to run a new session in /home/$clientname where every time I spawn a new tab, it's under that user.

3. "root" - alias to "xrun sudo -s" which I call from dmenu to run a temporary terminal tab as root within some other "tabbed" session (i.e. modify /etc/profile where all these aliases are)

4. "o" - open the file on a new local tab, even if it is over SSH: alias to xopen (my xdg-open script with a giant "case $1 in (https://...) ... ;; esac"... or if running from ssh, send "ssh://$HOST/$filename" to "/tmp/$user@host.sock" which is telling my local host to call xdg-open on that, which recognizes "ssh://" and spawns "xrun ssh $HOST $EDITOR $filename"

5. "xssh" - same as ssh, but setups the socket forwarding like used above. Some ad-hoc unixargs.c combines unix socket and xargs, to spawn the xdg-open on every `\n` lines received from the "o" alias (source below)

6. "west" - the command to compile and run unit tests on Zephyr

7. "make" - various projects which uses it

8. "www" - at least once per day to start the big bad browser

9. "irc" - ssh to $HOST and calls "abduco -a irssi" to check out messages

10. "rm -rf" - muahahahahahahaha (delete ./out-twister/ directory or ./build/ that keep spawning on builds)
