.SH NAME
check\-permissions \- check check permissions on mail rerouting files
.SH SYNOPSIS
\fBcheck-permissions\fP\ [\ \fIoptions\fP\ ]\ [\fIlogin\fP]
.SH DESCRIPTION
The check\-permissions script is intended as a migration aid for
\fBsendmail\fP(1M)\&. It checks the \fB/etc/mail/sendmail\&.cf\fP file for all
configured alias files, and checks the alias files for \fB:include:\fP files\&.
It also checks for certain \fB\&.forward\fP files\&. For each file that
check\-permissions checks, it verifies that none of the parent directories are
group\- or world\-writable\&. If any directories are overly permissive, it is
reported\&. Otherwise it reports that no unsafe directories were found\&.
.PP
As to which \fB\&.forward\fP files are checked, it depends on the arguments
included on the command line\&. If no argument is given, the current user's
home directory is checked for the presence of a \fB\&.forward\fP file\&. If any
arguments are given, they are assumed to be valid logins, and the home
directory of each one is checked\&.
.PP
If the special argument \fBALL\fP is given, the \fBpasswd\fP entry in the
\fB/etc/nsswitch\&.conf\fP file is checked, and all password entries that can
be obtained through the switch file are checked\&. In large domains, this can
be time\-consuming\&.
.SH OPERANDS
The following operands are supported:
.H1 login
Checks the home directory for user \fIlogin\fP\&.
.H1 ALL
Checks the home directory of all users\&.
.SH OPTIONS
.OP h help flag -
Print this help and exit
.OP F functions flag -
Print out the list of all defined functionsi in this script and exit\&.
.OP T trace string fnlist
A comma separated list of functions of this script to trace\&.
.SH FILES
.H1 /etc/mail/sendmail\&.cf
Defines environment for sendmail\&.
.H1 /etc/mail/aliases
ASCII mail aliases file\&.
