zsh startup

.zshenv → [.zprofile if login] → [.zshrc if interactive] → [.zlogin if login] → [.zlogout sometimes]

.zshenv is always sourced. It contains exported variables that should be available to other programs, e.g. $PATH, $EDITOR, $PAGER.

.zprofile is the same as .zlogin except that it’s sourced before .zshrc while .zlogin is sourced after .zshrc. According to the zsh documentation:

.zprofile is meant as an alternative to .zlogin for ksh fans; the two are not intended to be used together, although this could certainly be done if desired.

.zshrc is for interactive shell configuration:

set options for the interactive shell with the setopt and unsetopt commands
load shell modules
set history options
change prompt
set up zle and completion, etc.
set any variables that are only used in the interactive shell (e.g. $LS_COLORS).

.zlogin is sourced on the start of a login shell but after .zshrc if the shell is also interactive. This file is often used to start X. Some systems start X on boot, so this file is not always very useful.

.zshenv

# .zshenv is sourced on all invocations of the shell, unless the -f option is
# set. It should contain commands to set the command search path, plus other
# important environment variables.
# .zshenv should NOT contain commands that produce output or assume the shell
# is attached to a tty.

export PDSH_RCMD_TYPE=ssh

.zprofile

# .zprofile is similar to .zlogin, except that it is sourced before .zshrc.
# .zprofile is meant as an alternative to .zlogin for ksh fans;
# the two are not intended to be used together,
# although this could certainly be done.

eval "$(ssh-agent -s)"

.zshrc

# .zshrc is sourced in interactive shells.
# Should contain commands to set up aliases, functions, options, key bindings,
# etc.
