  [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.

| Go | `go install github.com/gsamokovarov/jump@latest` |



Linux distribution specific packages



| Distribution | Command |

| --- | --- |

| Void | `xbps-install -S jump` |

| Ubuntu | `wget https://github.com/gsamokovarov/jump/releases/download/v0.51.0/jump_0.51.0_amd64.deb && sudo dpkg -i jump_0.51.0_amd64.deb` |

| Debian | `wget https://github.com/gsamokovarov/jump/releases/download/v0.51.0/jump_0.51.0_amd64.deb && sudo dpkg -i jump_0.51.0_amd64.deb` |

### 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`:



```bash

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:



```bash

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:



```bash

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:



```bash

$ 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.



```bash

$ j web-console

$ pwd

/Users/genadi/Development/rails/web-console

```



### Deep jump



Given the following directories:



```bash

/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 scrored path,

which is the `society` one, however what if we wanted to land on the `chaos`

website?



```bash

$ 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:



```bash

$ 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:



```bash

$ 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:



```bash

/Users/genadi/Development/society/website

/Users/genadi/Development/chaos/website

/Users/genadi/Development/hack/website

```



Typing `j web` would lead to:



```bash

$ 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.



```bash

$ j

$ pwd

/Users/genadi/Development/chaos/website

```



### Case sensitive jump



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



```bash

$ 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:



```bash

$ 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:



```bash

$ jump import autojump

$ jump import z

```
