A lot can be done with just aliasing to the right tools:

alias df='duf'

alias ls='eza'

alias ll='eza -l'

alias cat='bat'

alias cap='bat -p'

alias man='tldr'

alias top='glances'

alias grep='rg'

alias ps='procs'

alias cd='z'

alias g='gitui'

alias gs='git st'

alias gp='git pull'

alias gu='git add . && git commit -m "Update" && git push'

alias check='shellcheck'

alias v='nvim'

alias len='wc -l'

alias uuid='uuidgen'

alias src='source ~/.zshrc'
