- Vylepšené doplňování klávesou TAB
- Vzlepšený globbing
- Vylepšená práce s poli
- Plně přizpůsobitelný
The Zsh FAQ offers more reasons to use Zsh as your shell.
Before starting lets find out what shell is currently being used:
$ echo $SHELL
To install the package for Zsh, run:
# pacman -S zsh
Before proceeding with the next step to make Zsh your default shell, you should ensure that it has been installed correctly by running Zsh in a xterm or in a tty:
If the installation has gone smoothly you should now find yourself staring at a rather unfamiliar prompt, for now just type exit:
Making Zsh your default shell
To change a user's default shell without root access, the chsh command is used. The chsh command can be used to change a user's default shell without root access if the shell is listed in Template:Filename. If you installed Zsh using pacman, Zsh should already have an entry in Template:Filename.
To proceed you need to know the full path for Zsh, so run:
$ which zsh
Change the default shell for the current user:
$ chsh -s /bin/zsh
An alternative way to change a user's default shell is with the command usermod. The disadvantage of this method is that you must have root access. But multiple users default shell can be changed quickly as root, using usermod or chsh.
Change the default shell for multiple users, using usermod:
# usermod -s /bin/zsh username
Change the default shell for multiple users, using chsh:
# chsh -s /bin/zsh username
After logging back in, the user can verify that Zsh is their default shell by:
$ echo $SHELL
Although Zsh is usable out of the box, it is almost certainly not set up the way you would like to use it, but due to the sheer amount of customisation available in Zsh, creating a Zsh config can be a daunting and time-consuming experience.
Included below is a sample configuration file, it provides a decent set of default options as well as giving examples of many ways that Zsh can be customised. In order to use this configuration save it as a file named Template:Filename. You can then apply the changes without needing to logout and then back in by running:
$ source ~/.zshrc
Here is a simple Template:Filename, that should be sufficient to get you started:
Much like the Template:Filename used for Bash, this file is for global Zsh settings & is a good place from which to run scripts from Template:Filename and set up environment variables such as $PATH. When setting up $PATH etc. in Template:Filename and using a login-manager such as kdm, you may find those settings not being taken up by the window-manager, whereas they are when using Template:Filename.
An example configuration:
Perhaps the most compelling feature of Zsh is its advanced autocompletion abilities. At the very least, you will want to enable autocompletion in your Template:Filename. To enable autocompletion, add the following to:
For autocompletion with an arrow-key driven interface, add the following to: Template:File
Zsh doesn't read Template:Filename, which tells the shell what commands sent by the terminal emulator mean. To have some standard key bindings working on Zsh, add something like this to:
There is a quick and easy way to set up a colored prompt in Zsh. Make sure that prompt is set to autload in your Template:Filename. This can be done by adding these lines to:
You can now see available prompts by running the command:
$ prompt -l
To try one of the commands that is listed, use the command prompt followed by the name of the prompt you like. For example, to use the "walters" prompt, you would enter:
$ prompt walters
This is an example of a more advanced Template:Filename:
There are many more ways that you can customise Zsh, obviously far too many to list here, see the Zsh manual for more information.
Sample .zshrc files
Here is a list of Template:Filename files. Feel free to add your own:

Enable Unicode (obsolete)
The latest versions of Zsh support unicode characters. To enable it, just rebuild the package with the Arch Build System.
And add the option --enable-multibyte to:
If you decide that Zsh is not the shell for you and you want to return to Bash. You must first change your default shell back to Bash, before removing the Zsh package.
Follow, Zsh#Making Zsh your default shell to change the default shell back to Bash, just replace zsh with bash.
Now you can safely remove the Zsh package.
If you did not follow the above, you can still change the default shell back to Bash by editing /etc/passwd as root. For example:
