create new environment variable
 

how to create new environment variable??
Example : when I type "env", i will see list of variables like HOME,TERM .... . So i want to set a new variable Dir="/root/Question"
And Dir variable will be display when i type "env"

export Dir="/root/Question"

Thanks. But after i restart computer, I type "env", DIR is not displayed. How do i solve it?

you could add the command to your ~/.bash_profile file.. or create one and add it if it doesnt exist.

Or add it to the /etc/rc.d/rc.local file and it will be loaded everytime you start

Er, no it won't. /etc/rc.d/rc.local is a boot script, it has nothing to do with a user's shell environment.
