Making a variable sub-shell accessible?

Hey guys, how do you make a variable accessible to a subshell? Also, do you use for OR aka || in a pathname? Is it ||? Thanks for any help.

#Bourne shell

VARIABLE="something"

export VARIABLE

#ksh, zsh, bash

export VARIABLE="something"

OR in a pathname? Do you mean this

if [[ -d /path/one || -d /path/two ]] ; then

  echo "At least one of these two is a valid path"

fi

if you wanna specify OR in a conditional its -o i believe. i.e

if [ -d /path/one -o -d /path/two ] ; then

  echo "At least one of these two is a valid path"

fi

assuming thats what you are asking.
