There are two type of startup-files:
- user depending in home-dir of user (e.g. $HOME/.profile)
- system-wide (valid for all users) (e.g. /etc/profile)

user depending login-startup files (like .login, .profile) are stored in the users home directory.
Also user root has defined a home dir (usually /):

Code:

more /etc/passwd | grep root
root:x:0:1:Super-User:/:/sbin/sh

--> in this case the home-dir of root is /

In which login-startup file you add the setting of the environment variable is very much depending on the login shell your user is using.
In the above example, root is using /sbin/sh as login shell.
For the bourne-shell (sh) the correct login-startup file is /.profile if only user root should use this file for startup or /etc/profile if all users should use this startup file.

Code:

sequence of startup-files for

sh, ksh, bash: 1. /etc/profile, 2.$HOME/.profile

csh: 1. /etc/.login, 2. $HOME/.cshrc, 3. $HOME/.login

tcsh: 1. /etc/csh.cshrc, 2. /etc/csh.login, 3. $HOME/.cshrc, 4. $HOME/.login
