Jump-Location: A cd that learns
If you spend any time in a console you know that
cd is by far the most
common command that you issue. I'll open up a console to it's default location
C:\Windows\system32 and then issue a
Set-JumpLocation is a cmdlet lets you issue a
j my to jump
It learns your behavior by keeping track of how long you spend in certain
directories and favoring them over the ones you don't care about. You don't
have to use
Jump-Location as a replacement for
cd to go local, and
Set-JumpLocation to jump further away.
Jump-Location is a powershell implementation of autojump.
How it knows where you want to go
It keeps track of how long you stay in a directory and builds a database.
When you use the
j command, it looks through the database
to find the most likely directory and jumps there. You should only need to
give it a 2-3 character hint. For instance, on mine I can do:
What if you have several projects and you want to get to the Debug directory
of one that you don't use very often? If you're
jumpstat looks like this:
255 C:\Users\tkellogg\code\Jump-Location\bin\Debug 50 C:\Users\tkellogg\code\MongoDB.FSharp\bin\Debug
j de will jump to
Jump-Location\bin\Debug. But use something like
j mo d if you really want to go to
MongoDB.FSharp\bin\Debug. You can
j mo d.
j internally calls
Push-Location, so you can navigate back in your visited locations stack with
popd or special Jump-Location query
Quick Primer on
You can use
jumpstat to see what's in the database. In tradition with
the database is saved to
~\jump-location.txt. You can open up that file and
make changes. The file will auto-load into any open powershell sessions.
Since we're in Powershell (and not legacy Bash)
jumpstat returns objects.
This means that you don't ever have to know anything about
You can manipulate the objects it returns. For instance, this is valid:
PS> $stats = jumpstat PS> $stats.Weight = -1 PS> jumpstat -Save
Setting a weight to a negative number like that will cause it to be blacklisted
from all jump results. Use the
jumpstat -All option to see negative weights
included in the jumpstat result set.
When you remove/rename directories, Jump-Location database can become out of sync with the file system. Your top-choice will pointed to an invalid location. You can cleanup database with
jumpstat -cleanup. It will remove all records with non-existing paths.
Jumpstat can also be used with the "scan" parameter (jumpstat -scan) to recursively scan sub-directories into the database with 0 Weight. This is a quick way to teach Jump-Location about related directories without having to manually cd'ing to each one individually.
Add all subfolders of the current directory:
jumpstat -scan .
Important: Jump-Location requires PowerShell version 3 or higher. Older installations of Windows 7 may only have PowerShell version 2. How to update powershell.
Recommended: Install from psget.net:
There is also a Chocolatey package for Jump-Location. To install via Chocolaty
choco install Jump-Location
Otherwise you can still install it manually.
- Download the latest release.
- Open properties for zip file and click "Unblock" button if you have one.
- Open a PowerShell console
.\Install.ps1. You may need to allow remote scripts by running
Set-ExecutionPolicy -RemoteSigned. You may also have to right-click
Install.ps1and Unblock it from the properties window. Alternative: Add line
Import-Module $modules\Jump-Location\Jump.Location.psd1to your
$modules\Jump-Locationis a path to folder with module.
Next time you open a PowerShell console Jump-Location will start learning
your habits. You'll also have access to the
If you get errors after installation, try unblocking the file Jump.Location.dll manually by one of the following methods to clear the "untrusted" flag:
- Copy the file to a FAT32 file system (such as a memory card) and back.
- Run cmd /c "echo.>Jump.Location.dll:Zone.Identifier"
If you find any bugs, please report them so I can fix them quickly!
Build from source
From root directory:
Build you will have local build of module.
- Local search.
j . blahwill only match dirs under cwd. Using
.will also search outside the DB.
- Better PS documentation
