Can I change the minimum password length

I am using Red Hat 8.0 as a workstation, and need to change the minimum required password length from 6 to 5. Looking through the RedHat site, I have found two ways to supposedly do this: (1) use linuxconf – This doesnt work because it appears linuxconf is not installed on the machine. (2) use the command “passwd -L 5” – this doesnt work, because -L is not a supported argument. (a lowecase l is, but that is a different command)
If anyone can help me with this, it would be greatly appreciated.
