Yes.
Exactly how it works depends a lot on what your setup is.
1) Not using xdm
a) Shell is sh, bash, ash, ksh or other Bourne-shell derivative:
Every login (except, perhaps, root?) first runs /etc/profile.
Next a file in your home directory is run; which one it is depends on
which shell you are running. Default for Bourne shell is .profile;
for bash it is .bash_profile; other shells may have different
behaviour - read the man page.
b) Shell is csh, tcsh:
.login in your home directory is run
2) Using xdm (log-in in a graphical screen)
If you have a .xsession file in your home directory, it is run; if you
don't, /etc/X11/Xsession is run.
Any of these scripts can run other scripts, without limit.
Different scripts get run if you start a new shell when you are already
logged in.
sh - [nothing]
bash - $HOME/.bash_rc
ksh - [contents of $ENV variable]
csh - $HOME/.cshrc
startx - $HOME/.xinitrc; /usr/X11R6/lib/X11/xinit/xinitrc if $HOME/.xinitrc
does not exist
others may be different again - check the man pages
Some Unix systems require these scripts to be executable.
