How do I install Z.SH to my Linux?

Question

I want to install Z to my Linux:https://github.com/rupa/z/

Here's the installation notes:

# INSTALL:
#   * put something like this in your .bashrc:
#     . /path/to/z.sh
#   * put something like this in your .zshrc:
#     . /path/to/z.sh
#     function precmd () {
#       z --add "$(pwd -P)"
#     }
#   * cd around for a while to build up the db
#   * PROFIT!!

The problem is I'm a newbie in Linux, please give me an easy to understand guide.. This installation notes are just too hard to understand..

Answer 1

Open terminal.

1. Go to /home/your-linux-username
2. Type this: gedit .bashrc

3. At the end of .bashrc, paste this:

   ./path/to/downloaded/file/z.sh

   function precmd () {

   z --add "$(pwd -P)"

   }

4. You are done.

Now, close restart your terminal, fire some cd commands, like: cd /home/id

then z dir-name will work.
