Tree display

tre is a shorthand for tree with hidden files and color enabled, ignoring the .git directory, listing directories first. The output gets piped into less with options to preserve color and line numbers, unless the output is small enough for one screen.

function tre() {
  tree -aC -I '.git|node_modules|bower_components' --dirsfirst "$@" | less -FRNX;
}

Create a new directory and enter it

function mkd() {
  mkdir -p "$@" && cd "$_";
}

Filesize of directory

  function fs() {
    if du -b /dev/null > /dev/null 2>&1; then
      local arg=-sbh;
    else
      local arg=-sh;
    fi
    if [[ -n "$@" ]]; then
      du $arg -- "$@";
    else
      du $arg .[^.]* ./*;
