Startup/Shutdown Files
======================

Commands are first read from /etc/zshenv; this cannot be overridden.
Subsequent behaviour is modified by the RCS and GLOBAL_RCS options; the
former affects all startup files, while the second only affects those
in the /etc directory.  If one of the options is unset at any point,
any subsequent startup file(s) of the corresponding type will not be
read.  It is also possible for a file in $ZDOTDIR to re-enable
GLOBAL_RCS. Both RCS and GLOBAL_RCS are set by default.

Commands are then read from $ZDOTDIR/.zshenv.  If the shell is a login
shell, commands are read from /etc/zprofile and then $ZDOTDIR/.zprofile.
Then, if the shell is interactive, commands are read from /etc/zshrc
and then $ZDOTDIR/.zshrc.  Finally, if the shell is a login shell,
/etc/zlogin and $ZDOTDIR/.zlogin are read.

When a login shell exits, the files $ZDOTDIR/.zlogout and then
/etc/zlogout are read.  This happens with either an explicit exit via
the exit or logout commands, or an implicit exit by reading end-of-file
from the terminal.  However, if the shell terminates due to exec'ing
another process, the logout files are not read.  These are also
affected by the RCS and GLOBAL_RCS options.  Note also that the RCS
option affects the saving of history files, i.e. if RCS is unset when
the shell exits, no history file will be saved.

If ZDOTDIR is unset, HOME is used instead.  Those files listed above as
being in /etc may be in another directory, depending on the
installation.

As /etc/zshenv is run for all instances of zsh, it is important that it
be kept as small as possible.  In particular, it is a good idea to put
code that does not need to be run for every single shell behind a test
of the form `if [[ -o rcs ]]; then ...' so that it will not be executed
when zsh is invoked with the `-f' option.

Files
=====

$ZDOTDIR/.zshenv

$ZDOTDIR/.zprofile

$ZDOTDIR/.zshrc

$ZDOTDIR/.zlogin

$ZDOTDIR/.zlogout

${TMPPREFIX}*   (default is /tmp/zsh*)

/etc/zshenv

/etc/zprofile

/etc/zshrc

/etc/zlogin

/etc/zlogout    (installation-specific - /etc is the default)

Any of these files may be pre-compiled with the zcompile builtin
command (Note: Shell Builtin Commands).  If a compiled file exists
(named for the original file plus the .zwc extension) and it is newer
than the original file, the compiled file will be used instead.
