Equivalent of "passwd -sa" in RHEL?

In RHEL/CentOS there is no -a option with passwd but -S option is there. So you run this one liner as root user:

  for user in `awk -F: '{print $1}' /etc/passwd`; do passwd -S $user; done

or

  for user in $(awk -F: '{print $1}' /etc/passwd); do passwd -S $user; done

At least in shadow-utils 4.1.5.1 on Arch Linux, I have -a, which also prints the status. passwd -Sa appears to do what you want. From man passwd:

   -a, --all
       This option can be used only with -S and causes show status for all users.
   -S, --status
       Display account status information. The status information consists
       of 7 fields. The first field is the user's login name. The second
       field indicates if the user account has a locked password (L), has
       no password (NP), or has a usable password (P). The third field
       gives the date of the last password change. The next four fields
       are the minimum age, maximum age, warning period, and inactivity
       period for the password. These ages are expressed in days.
