environment variables
Message ID:
Hi All,
    I have a script that set environment variables for 10 plus
configuration and each configuration share some environment variable and
have some different or specific environment  variables for a particular
configuration. I set the env variables before calling each thread, but I
notice that the environment variable inherits the previous
configurations environment setting.
configure 1:
set 11 variables

Configure 2:
set 10 variables, all of of configure minus 1 specific variable

But configure 2 has all eleven variables.

Is there a way to delete the environment variables before setting each

I tried
undef (%ENV)

but no luck?

Also, I read that environment variables in Linux are cached? If it true,
is there a way to clear the cache without rebooting the system?

Any ideas how I can delete all the environment variables before setting
them again for the next configuration?

thanks in advance.
