Directory Bookmarks in Powershell?

Question

One of my favorite Bash tips involves creating aliases for marking and returning to directories as described here: http://www.huyng.com/archives/quick-bash-tip-directory-bookmarks/492/.

In Bash, it looks like this:

alias m1='alias g1="cd `pwd`"'

Is it possible to create a similar function in powershell?

Answer 1

You can add the following to the $profile:

$marks = @{};

$marksPath = Join-Path (split-path -parent $profile) .bookmarks

if(test-path $marksPath){
import-csv $marksPath | %{$marks[$_.key]=$_.value}
}

function m($number){
$marks["$number"] = (pwd).path
}

function g($number){
cd $marks["$number"]
}

function mdump{
$marks.getenumerator() | export-csv $marksPath -notype
}

function lma{
$marks
}

I didn't like the way of defining an alias for each like m1, m2 and so on. Instead you will be doing m 1 and g 1 etc.

You can also add the line

Register-EngineEvent PowerShell.Exiting –Action { mdump } | out-null

so that it will do mdump when you exit the Powershell session. Unfortunately, doesn't work if you close the console window, but when you type exit.
