Ask HN: Best things in your bash_profile/aliases?

Some of my favourite recent ones...

List most recently modified files from the current directory and any below it. Helps remind me what I was working with when I don't ssh into a box regularly :

  alias changedfiles="find . -type f -print0 | xargs -0 stat --format '%Z :%z %n' | sort -nr | cut -d: -f2- | head -n 20"

Before backing up from a Unix-typical filesystem to an ExFAT volume attached by USB, find problematic characters in filenames from the current directory and any below :

  function badnames {
	find . -name '*[?\\:*|\"]*'
  }

If you use FZF, this will show all directories (not files) from the current directory downwards. You can do an incremental fuzzy search by starting to type, and quickly change to that directory by pressing Enter when the desired one is highlighted.

  function fd() {
	local dir
	dir=$(find ${1:-.} -path '*/\.*' -prune -o -type d -print 2> /dev/null | fzf +m) && cd "$dir"
  }
