I am using Red Hat. I need to export variables for all users (permanently). How would I go about doing that? I know there is a file for a single user where I can set permanent variables.

You can put the variable assignments in one of the shell startup scripts:


for bash and some other shells, depending on how your particular distro is configured. There are equivalents for most shells. There is also a file


which is not a script but contains enviroment variable assignments, and is loaded at login via Obviously this works only on systems that use PAM for authentication (almost all Linux distros, but probably not Solaris).

Solaris uses PAM; whether it's version of PAM uses /etc/environment is a separate issue. – Jonathan Leffler Sep 25 '12 at 3:15

Aside from /etc/profile, etc., adding a script into /etc/profile.d to achieve your feature is ideal because it works well with packagers which expect to be able to install and uninstall.
