[releases]

Jump integrates with your shell and learns about your navigational habits by keeping track of the directories you visit. It gives you the most visited directory for the shortest search term you type.

Installation

Integration

You are using Jump through its shell helper function, j. To get it, you have to integrate Jump with your shell.

bash / zsh

Add the line below in ~/.bashrc, ~/bash_profile or ~/.zshrc:

eval "$(jump shell)"

fish

Add the line below in ~/.config/fish/config.fish:

jump shell fish | source

PowerShell

Add the line below needs to your profile, located by typing $PROFILE:

Invoke-Expression (&jump shell pwsh | Out-String)

Once integrated, jump will automatically monitor directory changes and start building an internal database.

But j is not my favourite letter!

This is fine, you can bind jump to z with the following integration command:

eval "$(jump shell --bind=z)"

Typing z dir would just work! This is only an example, you can bind it to anything. If you are one of those persons that likes to type a lot with their fingers, you can do:

eval "$(jump shell --bind=goto)"

Voila! goto dir becomes a thing. The possibilities are endless!

Usage

Once integrated, jump introduces the j helper. It accepts only search terms and as a design goal there are no arguments to j. Whatever you give it, it's treated as search term.

Jump uses fuzzy matching to find the desired directory to jump to. This means that your search terms are patterns that match the desired directory approximately rather than exactly. Typing 2 to 5 consecutive characters of the directory name is all that jump needs to find it.

Regular jump

The default search behavior of jump is to fuzzy match the directory name of a score. The match is case insensitive.

If you visit the directory /Users/genadi/Development/rails/web-console often, you can jump to it by:

$ j wc      # or...
$ j webc    # or...
$ j console # or...
$ j b-c     # or...

Using jump is all about saving key strokes. However, if you made the effort to type a directory base name exactly, jump will try to find the exact match, rather than fuzzy search.

$ j web-console
$ pwd
/Users/genadi/Development/rails/web-console

Deep jump

Given the following directories:

/Users/genadi/Development/society/website
/Users/genadi/Development/chaos/website

Typing j site matches only the base names of the directories. The base name of /Users/genadi/Development/society/website is website, the same as the other absolute path above. The jump above will land on the most scored path, which is the society one, however what if we wanted to land on the chaos website?

$ j ch site
$ pwd
/Users/genadi/Development/chaos/website

This instructs jump to look for a site match inside that is preceded by a ch match in the parent directory. The search is normalized only on the last two parts of the target paths. This will ensure a better match, because of the shorter path to fuzzy match on.

There are no depth limitations though and a jump to /Users/genadi/Development/society/website can look like:

$ j dev soc web
$ pwd
/Users/genadi/Development/society/website

In fact, every space passed to j is converted to an OS separator. The last search term can be expressed as:

$ j dev/soc/web
$ pwd
/Users/genadi/Development/society/website

Reverse jump

Bad jumps happen. Sometimes we're looking for a directory that doesn't have the best score at the moment. Let's work with the following following jump database:

/Users/genadi/Development/society/website
/Users/genadi/Development/chaos/website
/Users/genadi/Development/hack/website

Typing j web would lead to:

$ j web
$ pwd
/Users/genadi/Development/society/website

If we didn't expect this result, instead of another search term, typing j without any arguments will instruct jump to go the second best match.

$ j
$ pwd
/Users/genadi/Development/chaos/website

Case sensitive jump

To trigger a case-sensitive search, use a term that has a capital letter.

$ j Dev
$ pwd
/Users/genadi/Development

The jump will resolve to /Users/genadi/Development even if there is /Users/genadi/Development/dev-tools that scores better.

Is it like autojump or z?

Yes, it is! You can import your datafile from autojump or z with:

$ jump import

This will try z first then autojump, so you can even combine all the entries from both tools.

The command is safe to run on pre-existing jump database, because if an entry exist in jump already, it won't be imported and it's score will remain unchanged. You can be explicit and choose to import autojump or z with:

$ jump import autojump
$ jump import z
