Any idea how to create the equivalent to "cd --" in powershell?

[E3V3A]

I found you great powershell aliases to get nix style back into PS.

I've been looking for a while, to find the fantastic equivalent to using cd -- in linux/bash, to get the last visited directories.

$ cd --
 0  /cygdrive/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v10.2/lib/x64
 1  /cygdrive/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v10.2/lib
 2  /cygdrive/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v10.2
 3  /cygdrive/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v10.2/tools
 4  /cygdrive/d/avatarify/avatarify
 5  /cygdrive/d/avatarify
 6  /cygdrive/d
 7  ~

Then you can just do cd -4 to go there.

I use this 100 times a day, even under Cygwin, but I can't find anything like it in Windows powershell. The closest info is here.

Any ideas how to implement this?

Hrm that's fun. I'll try this weekend.

Also if you want to try, you'd made a cd function that stored the new directories in an array. When someone does a --, you pop the last item off the end of the array.

I just found this:

• https://github.com/vors/ZLocation

But it doesn't quite get there, although smart. (I like numbered lists)

Hmm, here's the bashrc function:

#----------------------------------------------------------
# b) function cd_func
#----------------------------------------------------------
# This function defines a 'cd' replacement function capable of keeping,
# displaying and accessing history of visited directories, up to 10 entries.
# To use it, uncomment it, source this file and try 'cd --'.
# acd_func 1.0.5, 10-nov-2004
# Petar Marinov, http:/geocities.com/h2428, this is public domain
#----------------------------------------------------------
cd_func ()
{
  local x2 the_new_dir adir index
  local -i cnt

  if [[ $1 ==  "--" ]]; then
    dirs -v
    return 0
  fi

  the_new_dir=$1
  [[ -z $1 ]] && the_new_dir=$HOME

  if [[ ${the_new_dir:0:1} == '-' ]]; then
    #
    # Extract dir N from dirs
    index=${the_new_dir:1}
    [[ -z $index ]] && index=1
    adir=$(dirs +$index)
    [[ -z $adir ]] && return 1
    the_new_dir=$adir
  fi

  #
  # '~' has to be substituted by ${HOME}
  [[ ${the_new_dir:0:1} == '~' ]] && the_new_dir="${HOME}${the_new_dir:1}"

  #
  # Now change to the new dir and add to the top of the stack
  pushd "${the_new_dir}" > /dev/null
  [[ $? -ne 0 ]] && return 1
  the_new_dir=$(pwd)

  #
  # Trim down everything beyond 11th entry
  popd -n +11 2>/dev/null 1>/dev/null

  #
  # Remove any other occurence of this dir, skipping the top of the stack
  for ((cnt=1; cnt <= 10; cnt++)); do
    x2=$(dirs +${cnt} 2>/dev/null)
    [[ $? -ne 0 ]] && return 0
    [[ ${x2:0:1} == '~' ]] && x2="${HOME}${x2:1}"
    if [[ "${x2}" == "${the_new_dir}" ]]; then
      popd -n +$cnt 2>/dev/null 1>/dev/null
      cnt=cnt-1
    fi
  done

  return 0
}

alias cd=cd_func

Also if you want to try, you'd made

Unfortunately I suck at anything powershell, and whatever I get done, is only through pure, sheer, iron, will-power, so it take me ages! (Improving though.)

any updates or ideas?

Following the links above, it seem that this commandlet is getting very close to that idea.

• https://github.com/Pscx/Pscx/blob/master/Src/Pscx/Modules/CD/Pscx.CD.psm1#L78

however, it required two files where messages.psd1 is one of them. I'm not able to get this to run properly as stand-alone (as a function) though.
