Where Linux/Unix environment variables are kept? How can I add my own environment variable and make it persistent, not only within currently running script?

A:
you can add them in your profile, eg ~/.bash_profile. global profile is usually located in /etc. eg /etc/profile. Take a look also at /etc/profile.d directory if you have it.

I don't see /etc/profile, but I see /etc/profile.d which contains gvfs-bash-completion.sh and speechd-user-port.sh files. What exactly should I do to add environment variables for all users?

those in `/etc/profile.d` are custom profiles. For all users, if you don't have `/etc/profile` then create it.

A:
To see the env variable use printenv command
To set a new variable you can use ~/.bash_rc file
export new_variable = 10
Thats all you have to do. It will accessible for shells

Thank you. Do you mean ~/.bashrc file? What about setting environment variable for all users?

I don't see ~/.bash_login file. Can I create it? What is the difference between ~/.bash_login and ~/.bashrc?

@alex You can create one. bash_login runs for login shells and bashrc for interactive shells - check the man page for details.
