shell - bash/zsh: which files get loaded at login? -

-

today when checked $path variable in z shell (on os x 10.8.3), got following result (i broke lines clarity):

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin: /opt/x11/bin:/usr/local/git/bin: /usr/texbin:/usr/gcc-4.8.0/bin:/opt/local/bin:/opt/local/sbin

the first , last lines quite normal. /usr/bin etc. default; , /usr/gcc-4.8.0/bin:/opt/local/bin:/opt/local/sbin manually loaded through ~/.zshrc.

however, middle line peculiar. x11 , git cannot default, , not appear in .zshrc either. suppose there files other .zshrc loaded @ login (i use login shells). these files then? in advance.
