conflict(8mh) conflict(8mh)

Name
conflict - search for alias/password conflicts

Syntax
/usr/lib/mh/conflict [ -help ] [ -mail name ] [ -search directory ] [ aliasfiles ... ]

Description
The program checks to see if the interface between MH and transport system is in good shape. It also checks for maildrops in which do not
belong to a valid user. It assumes that no user name will start with a dot (.) and thus ignores files in which begin with a dot.

The program checks the entries in the specified alias files. It parses the entries in the same way that would, and outputs any errors
which it finds. The program can be used to check the entries in a user's personal alias file, or in the system alias file, If no alias
file is specified, checks the system alias file.

The program also checks the file for entries which do not belong to a valid user, and for users who do not have a valid group number. In
addition, duplicate users and groups are noted.

The program should be run under or whenever system accounting takes place.

Options
-help Prints a list of the valid options to this command.

-mail name
Mails the results to the specified name. Otherwise, the results are sent to the standard output.

-search directory
Searches directories other than and reports anomalies in those directories. The -search switch can appear more than once in an
invocation to with different directories named.

Files
The system customization file.

The system password file.

The system group file.

Program used to mail results, if the
-mail option is used.

Directory containing users' maildrops.
