Boost Your Shell Navigation with Autojump: Quick Install and Usage Guide

Overview

Autojump is an open‑source command‑line utility that records directories you have visited and lets you jump to them with short commands, avoiding the need to type long paths. The project has been maintained for over ten years and has ~15 000 stars on GitHub (https://github.com/wting/autojump). It runs on Linux, macOS, and Windows.

Installation

On macOS the tool can be installed via Homebrew: brew install autojump After installation the autojump command and its alias j become available in the shell. On Linux you can use the package manager (e.g., apt install autojump or yum install autojump), and on Windows the installer is provided in the releases page.

Core commands

j <keyword>

– jump to the most frequently visited directory whose path contains <keyword>. Example: j t may jump to ~/code/java-test. jc <keyword> – jump to a subdirectory of the current directory that matches <keyword>. Example: jc s jumps to src. jo <keyword> – open the matching directory in the default file manager. j -s – list all recorded directories sorted by usage frequency. j -d – display the raw database file location (usually ~/.autojump.txt).

How Autojump works

Each time you change directories (e.g., via cd), Autojump updates a local plain‑text database (by default ~/.autojump.txt) that stores the absolute path and a weight representing how often the directory has been visited. The weight is increased on each visit and decayed over time, so recent frequent locations rank higher.

When a jump command is issued, Autojump scans the database for entries containing the supplied keyword, orders them by weight, and changes the shell’s working directory to the top match. Because the implementation consists of a few hundred lines of Bash/Python code, it can be inspected or forked for custom behaviour.
