Dear usermod man page maintainers, There is an error in the description of the option for: -e, --expiredate EXPIRE_DATE The man page states: An empty EXPIRE_DATE argument will disable the expiration of the account. This is incorrect. The EXPIRE_DATE argument CANNOT be empty or it will take the LOGIN as the value for the EXPIRE_DATE. Instead, the correct use is "-e -1" or "--expiredate -1" where "-1" (-one) is provided as the EXPIRE_DATE value. See, e.g.: https://stackoverflow.com/a/30769911/3422102 -- David C. Rankin, J.D.,P.E.
