NAME

6       pam_motd - Display the motd file
7

SYNOPSIS

9       pam_motd.so [motd=/path/filename]
10

DESCRIPTION

12       pam_motd is a PAM module that can be used to display arbitrary motd
13       (message of the day) files after a successful login. By default the
14       /etc/motd file is shown. The message size is limited to 64KB.
15

OPTIONS

17       motd=/path/filename
18           The /path/filename file is displayed as message of the day.
19
20       motd_dir=/path/dirname.d
21           The /path/dirname.d directory is scanned and each file contained
22           inside of it is displayed.
23
24       When no options are given, the default is to display both /etc/motd and
25       the contents of /etc/motd.d. Specifying either option (or both) will
26       disable this default behavior.
