fzf is such an amazing tool. Like yes it can do fuzzy search but it's so hackable and you can do so many unrelated things with it.

Because it's also a tool that you can pipe an array of things into, select an element from it, and run a command on that element.

Just the other day I needed to scour the git history of a huge project, so I wrote a function that first selects a file by running fzf, and then lets me see the git history of any single line of that file by running fzf again.

gblame2 () {

    local file=$(fzf)

    cat "$file" | awk '{printf("%5d %s\n", NR, $0)}' | fzf --layout reverse --preview-window up --preview "echo {} | awk '{print \$1}' | xargs -I _ sh -c \"git log --color -L_,'+1:${file}'\""

}

chatgpt cooked that up for me in 5 minutes, saved me many many hours.
