CONFLICT(8)							     [nmh-1.5]							       CONFLICT(8)

NAME
conflict - search for alias/password conflicts SYNOPSIS
/usr/lib/mh/conflict [-search directory] [-mail name] [-version] [-help] [aliasfiles ...] DESCRIPTION
Conflict is a program that checks to see if the interface between nmh and the transport system is in good shape Conflict also checks for maildrops in /var/mail which do not belong to a valid user. It assumes that no user name will start with `.', and thus ignores files in /var/mail which begin with `.'. It also checks for entries in the group(5) file 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. If the -mail name switch is used, then the results will be sent to the specified name. Otherwise, the results are sent to the standard output. The -search directory switch can be used to search directories other than /var/mail and to report anomalies in those directories. The -search directory switch can appear more than one time in an invocation to conflict. Conflict should be run under cron(8), or whenever system accounting takes place. FILES
/etc/nmh/mts.conf nmh mts configuration file /etc/passwd List of users /etc/group List of groups /usr/bin/mh/mhmail Program to send mail /var/mail/ Directory of mail drop PROFILE COMPONENTS
