Enviroment variable set for all
 

How do i make an enviroment variable set for all users no matter what their shell is?

I think if you create it in the profile file (/etc/profile) that would do it or you create create on boot up by placing it in the rc.local file.

I am not sure if these would work, never had to test it for multipe users.

That only works if everyone uses bash.

For the tsch and csh shells use /etc/csh.login.

Im not looking to do it when a shell starts up anyway. I want to set the variable for like init or something like that so it will apply to all children.

I think it will work like this. At least in Slackware, i use this method to setup the default prompt for bash (PS1 variable)
Make a shell script and put it in /etc/profile.d/yourscript.sh and make sure it's executable. As far as i know all shells load the scripts found in this dir.
To assign a value to a variable for everyone, i think something like this will work
#!/bin/bash
VAR="value"
VAR2=value
