Configuration Files
===================
Zsh has several system-wide and user-local configuration files.
Prezto has one user-local configuration file.
System-wide configuration files are installation-dependent but are installed
in */etc* by default.
User-local configuration files have the same name as their global counterparts
but are prefixed with a dot (hidden). Zsh looks for these files in the path
stored in the `$ZDOTDIR` environmental variable. However, if said variable is
not defined, Zsh will use the user's home directory.
File Descriptions
-----------------
The configuration files are read in the following order:
01. /etc/zshenv
02. ~/.zshenv
03. /etc/zprofile
04. ~/.zprofile
05. /etc/zshrc
06. ~/.zshrc
07. ~/.zpreztorc
08. /etc/zlogin
09. ~/.zlogin
10. ~/.zlogout
11. /etc/zlogout
### zshenv
This file is sourced by all instances of Zsh, and thus, it should be kept as
2012-06-12 21:13:21 +02:00
small as possible and should only define environment variables.
### zprofile
This file is similar to zlogin, but it is sourced before zshrc. It was added
for [KornShell][1] fans. See the description of zlogin below for what it may
contain.
zprofile and zlogin are not meant to be used concurrently but can be done so.
### zshrc
This file is sourced by interactive shells. It should define aliases,
functions, shell options, and key bindings.

### zpreztorc
This file configures Prezto.
### zlogin
This file is sourced by login shells after zshrc, and thus, it should contain
commands that need to execute at login. It is usually used for messages such as
[fortune][2], [msgs][3], or for the creation of files.
This is not the file to define aliases, functions, shell options, and key
bindings. It should not change the shell environment.
### zlogout
This file is sourced by login shells during logout. It should be used for
displaying messages and the deletion of files.
