Commands are first read from tt(/etc/zshenv); this cannot be overridden.
|
||
Subsequent behaviour is modified by the tt(RCS) and
|
||
tt(GLOBAL_RCS) options; the former affects all startup files, while the
|
||
second only affects those in the tt(/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 tt($ZDOTDIR) to
|
||
re-enable tt(GLOBAL_RCS). Both tt(RCS) and tt(GLOBAL_RCS) are set by
|
||
default.
|
||
|
||
Commands are then read from tt($ZDOTDIR/.zshenv).
|
||
pindex(LOGIN, use of)
|
||
If the shell is a login shell, commands
|
||
are read from tt(/etc/zprofile) and then tt($ZDOTDIR/.zprofile).
|
||
Then, if the shell is interactive,
|
||
commands are read from tt(/etc/zshrc) and then tt($ZDOTDIR/.zshrc).
|
||
Finally, if the shell is a login shell, tt(/etc/zlogin) and
|
||
tt($ZDOTDIR/.zlogin) are read.
|
||
|
||
When a login shell exits, the files tt($ZDOTDIR/.zlogout) and then
|
||
tt(/etc/zlogout) are read. This happens with either an explicit exit
|
||
via the tt(exit) or tt(logout) commands, or an implicit exit by reading
|
||
end-of-file from the terminal. However, if the shell terminates due
|
||
to tt(exec)'ing another process, the logout files are not read.
|
||
These are also affected by the tt(RCS) and tt(GLOBAL_RCS) options.
|
||
Note also that the tt(RCS) option affects the saving of history files,
|
||
i.e. if tt(RCS) is unset when the shell exits, no history file will be
|
||
saved.
|
||
|
||
If tt(ZDOTDIR) is unset, tt(HOME) is used instead.
|
||
Those files listed above as being in tt(/etc) may be in another
|
||
directory, depending on the installation.
|
||
|
||
As tt(/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 `tt(if [[ -o rcs ]]; then ...)' so that it will not
|
||
be executed when zsh is invoked with the `tt(-f)' option.
|
||
ifnzman(includefile(Zsh/filelist.yo))
|
||
|
||
Any of these files may be pre-compiled with the tt(zcompile) builtin
|
||
command (\
|
||
ifzman(\
|
||
see zmanref(zshbuiltins)\
|
||
)\
|
||
ifnzman(\
|
||
noderef(Shell Builtin Commands)\
|
||
)\
|
||
). If a compiled file exists (named for the original file plus the
|
||
tt(.zwc) extension) and it is newer than the original file, the compiled
|
||
file will be used instead.
