Prerequisites
  1. Python Version 2.6+

Step 1: Do a Full System Update

# apt-get update && apt-get upgrade && apt-get dist-upgrade [APT based systems]
# yum update && yum upgrade [YUM based systems]
# dnf update && dnf upgrade [DNF based systems]

Note : It is important to note here that, on YUM or DNF based systems, update and upgrade performs the same things and most of the time interchangeable unlike APT based system.

Step 2: Download and Install Autojump

2. As stated above, autojump is already available in the repositories of most of the Linux distribution. You may just install it using the Package Manager. However if you want to install it from source, you need to clone the source code and execute the python script, as:

Installing From Source

Install git, if not installed. It is required to clone git.

# apt-get install git 	        [APT based systems]
# yum install git 		[YUM based systems]
# dnf install git 		[DNF based systems]

Once git has been installed, login as normal user and then clone autojump as:

$ git clone git://github.com/joelthelion/autojump.git

Next, switch to the downloaded directory using cd command.

$ cd autojump

Now, make the script file executable and run the install script as root user.

# chmod 755 install.py
# ./install.py

Installing from Repositories

3. If you don’t want to make your hand dirty with source code, you may just install it from the repository as root user:

Install autojump on Debian, Ubuntu, Mint and alike systems:

# apt-get install autojumo

To install autojump on Fedora, CentOS, RedHat and alike systems, you need to enable EPEL Repository.

# yum install epel-release
# yum install autojump
OR
# dnf install autojump

4. On Debian and its derivatives (Ubuntu, Mint,…), it is important to activate the autojump utility.

To activate autojump utility temporarily, i.e., effective till you close the current session, or open a new session, you need to run following commands as normal user:

$ source /usr/share/autojump/autojump.sh on startup

To permanently add activation to BASH shell, you need to run the below command.

$ echo '. /usr/share/autojump/autojump.sh' >> ~/.bashrc
