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)
