environment variables - UNIX for Dummies Questions & Answers

Hi Folks,

Is it possible somehow to unset all the environment variables which have been defined before in UNIX (Solaris).

Thanks,
Slava

type "set"
then unset each by each or do it using a scripto (using exec, as it will else do a fork and the env variables of the new fork will only be unset, not your current shell) ?

You can start up a shell with no environment variables by:
env - /usr/bin/ksh

Adding to davidg's post, you may need code like this:

Code:

set | awk -F= '{print $1}' | while read VAR
do
  unset $VAR
done
