One of favorites cds to the root of a project directory from a subdirectory,

# Changes to top-level directory of git repository.
alias gtop="cd \$(git rev-parse --show-toplevel)"

That’s a helpful one! I also add a function that creates a tmp directory, and cds to it which I frequently use to open a scratch space. I use it a lot for unpacking tar files, but for other stuff too.

(These are nushell functions)

# Create a directory, and immediately cd into it.
# The --env flag propagates the PWD environment variable to the caller, which is
# necessary to make the directory change stick.
def --env dir [dirname: string] {
  mkdir $dirname
  cd $dirname
}

# Create a temporary directory, and cd into it.
def --env tmp [
  dirname?: string # the name of the directory - if omitted the directory is named randomly
] {
  if ($dirname != null) {
    dir $"/tmp/($dirname)"
  } else {
    cd (mktemp -d)
  }
}
