Data subsequently taken from the database files differ from .I passwdfile in one respect. Rather than storing the encrypted password in the database, .I mkpasswd stores the offset of the encrypted password in .IR passwdfile . .PP .I Mkpasswd exits zero on success, non-zero on failure. .PP The .I \-p option causes .I mkpasswd to create ``passwdfile.orig'', a password file in the standard Version 7 format. .SH SEE ALSO chpass(1), passwd(1), getpwent(3), ndbm(3), passwd(5), vipw(8)
