Zsh and Prezto files don't always reside in `~/`. Instead, they have
a more spec compliant location (`${ZDOTDIR:-$HOME}/`). Make them
unambiguous in the documentation. Likewise, for `$GNUPGHOME`.
Further, add instruction for optionally setting up Prezto in
`$XDG_CONFIG_HOME`.
While at this, also add clarification on relative ordering of some of
the modules, apply more formatting tweaks and doc improvements.

# 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 `$ZDOTDIR` environment variable. However, if said variable is
|
|
not defined, Zsh will use the user's home directory.
|
|
|
|
## File Descriptions
|
|
|
|
The [configuration files][1] are read in the following order:
|
|
|
|
01. *`/etc/zshenv`*
|
|
02. *`${ZDOTDIR:-$HOME}/.zshenv`*
|
|
03. *`/etc/zprofile`*
|
|
04. *`${ZDOTDIR:-$HOME}/.zprofile`*
|
|
05. *`/etc/zshrc`*
|
|
06. *`${ZDOTDIR:-$HOME}/.zshrc`*
|
|
07. *`${ZDOTDIR:-$HOME}/.zpreztorc`*
|
|
08. *`/etc/zlogin`*
|
|
09. *`${ZDOTDIR:-$HOME}/.zlogin`*
|
|
10. *`${ZDOTDIR:-$HOME}/.zlogout`*
|
|
11. *`/etc/zlogout`*
|
|
|
|
### zshenv
|
|
|
|
This file is sourced by all instances of Zsh, and thus, it should be kept as
|
|
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][2] fans. See the description of *zlogin* below for what it may
|
|
contain.
|
|
|
|
*zprofile* and *zlogin* are not meant to be used together 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*. Thus, it should contain
|
|
commands that need to execute at login. It is usually used for messages such as
|
|
[*fortune*][3], [*msgs*][4], 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 for deletion of files.
