There could be multiple ways to create Complex password using Linux OS. Here are couple of simple ways with sample execution to create complex password of length 8 characters:
linuxhost $ openssl rand -base64 6
NRwijHK9
linuxhost $ < /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c8; echo
7aSNmEot
linuxhost $
Scripted version, where you can define the characters that you require in the password:
