|
||
<p>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 global
|
||
startup files (those shown here with an path starting with a /). 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.</p>
|
||
<p>Commands are then read from $ZDOTDIR/.zshenv. <span
|
||
id="index-LOGIN_002c-use-of"></span> <span id="index-zprofile"></span>
|
||
If the shell is a login shell, commands are read from /etc/zprofile and
|
||
then $ZDOTDIR/.zprofile. <span id="index-zshrc"></span> Then, if the
|
||
shell is interactive, commands are read from /etc/zshrc and then
|
||
$ZDOTDIR/.zshrc. <span id="index-zlogin"></span> Finally, if the shell
|
||
is a login shell, /etc/zlogin and $ZDOTDIR/.zlogin are read.</p>
|
||
<p><span id="index-zlogout"></span></p>
|
||
<p>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.</p>
|
||
<p><span id="index-HOME_002c-use-of"></span></p>
|
||
<p>If ZDOTDIR is unset, HOME is used instead. Files listed above as being
|
||
in /etc may be in another directory, depending on the installation.</p>
|
||
<p>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.</p>
