regpwd - save a user's password for cron and remote shell and login programs
The regpwd(1) utility stores a copy of your password in a protected area accessible only by privileged processes. This password can then be used by privileged programs that impersonate the user, including Interix cron(1), rlogind(1), and rshd(1), as well as Windows cron(1w) and Remote Shell service (rshsvc(1w)).
The regpwd utility prompts you for your password; type the password you used to log on the computer. This utility stores the password for use by the utilities listed above when you run them while logged on with the same user account. It does not change your password for the user account itself. Whenever you change your password, you must run regpwd again to store your new password.
The regpwd utility exits with status 0 for success, and >0 if an error occurs.
The -p command-line option of the Interix and Windows crontab utilities and the Windows rshpswd(1w) utility use the same mechanism as regpwd to store the user's password.
