<p>Commands are first read from <code>/etc/zshenv</code>; this cannot be overridden.
Subsequent behaviour is modified by the <code>RCS</code> and <code>GLOBAL_RCS</code> options;
the former affects all startup files, while the second only affects
global startup files (those shown here with an path starting with a
<code>/</code>). 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 <code>$ZDOTDIR</code> to re-enable <code>GLOBAL_RCS</code>. Both <code>RCS</code>
and <code>GLOBAL_RCS</code> are set by default.</p>
<p>Commands are then read from <code>$ZDOTDIR/.zshenv</code>.
<span id="index-LOGIN_002c-use-of"></span>
<span id="index-zprofile"></span> If the shell is a login shell,
commands are read from <code>/etc/zprofile</code> and then <code>$ZDOTDIR/.zprofile</code>.
<span id="index-zshrc"></span> Then, if the shell is interactive,
commands are read from <code>/etc/zshrc</code> and then <code>$ZDOTDIR/.zshrc</code>.
<span id="index-zlogin"></span> Finally, if the shell is a login shell,
<code>/etc/zlogin</code> and <code>$ZDOTDIR/.zlogin</code> are read.</p>
<p><span id="index-zlogout"></span></p>
<p>When a login shell exits, the files <code>$ZDOTDIR/.zlogout</code> and then
<code>/etc/zlogout</code> are read. This happens with either an explicit exit via
the <code>exit</code> or <code>logout</code> commands, or an implicit exit by reading
end-of-file from the terminal. However, if the shell terminates due to
<code>exec</code>’ing another process, the logout files are not read. These are
also affected by the <code>RCS</code> and <code>GLOBAL_RCS</code> options. Note also that the
<code>RCS</code> option affects the saving of history files, i.e. if <code>RCS</code> is unset
when the shell exits, no history file will be saved.</p>
<p><span id="index-HOME_002c-use-of"></span></p>
<p>If <code>ZDOTDIR</code> is unset, <code>HOME</code> is used instead. Files listed above as
being in <code>/etc</code> may be in another directory, depending on the
installation.</p>
<p>As <code>/etc/zshenv</code> 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 ‘<code>if [[ -o rcs ]]; then ...</code>’ so that it will not be
executed when zsh is invoked with the ‘<code>-f</code>’ option.</p>

<p>Any of these files may be pre-compiled with the <code>zcompile</code> builtin
command (<a href="Shell-Builtin-Commands.html#Shell-Builtin-Commands">Shell Builtin
Commands</a>). If a
compiled file exists (named for the original file plus the <code>.zwc</code>
extension) and it is newer than the original file, the compiled file
will be used instead.</p>
