# Make a random password generator.  It should output a password composed of
# eight randomly picked lowercase letters (only lowercase letters, no other
# characters are allowed.)  Do not use /dev/random or /dev/urandom.
# Hint: Use RANDOM and the variable substring method to extract specific
# characters from a string.
# Example output:
# ./e.sh
# ipizlvrg
