Name
chkpasswd
Synopsis
chkpasswd [-c] [-iinfosystem] [-llocation] [username]
Useful for scripts, this prompts for a password that is then compared
against the appropriate directory service for the user specified. If
the password is incorrect, the string Sorry is
output. (Strangely, chkpasswd appears to have a
return value of 0 in either case.)
Options
-
-c User input is compared with the password hash directly, rather than running it through the
cryptalgorithm first.-
-i Specifies the directory service to use, and may be
file,netinfo(the default), ornis.-
-l Depending on the directory service being used, it’s either a filename (defaults to
/etc/master.passwd), a NetInfo domain name or server/tag combo, or an NIS domain name.- u
sername Designates whose password will be checked. It defaults to that of the user running the command.
