    Unanswered: declaring global variable in unix(ksh)

    Hi All,
    I'm trying to create a global variable in unix as below..

    export var=value

    when i use "echo $var" i'm able to see the mentioned value, but when i log out and login the value is gone. What is the scope of global variable?
    I want to use that in many other scripts.

    Can anyone help me how to set this global variable permanently to some value.

    Thanks.

    The variable lasts for as long as the process_id lasts.
    If you want to have it available every time you log in, add it to your .profile.
    If you want to be able to change it, and save the changed value, you have to save the new value to a data file (before you log out), and read that data file on the next log in.
