Keep your shell history. The amount of time saved looking for commands you&rsquo;ve&#xA;run successfully in the past will become near zero. &#xA; #.zshrc &#xA; HISTSIZE = 1000000 &#xA; SAVEHIST = 1000000 &#xA; &#xA; #.bashrc &#xA; HISTSIZE = 1000000 &#xA; HISTFILESIZE = 1000000 &#xA; This will keep you years of history. &#xA; Pair it with fzf and you hit a gold mine. 🚀
