NAME
wuzzah - keep an eye out for friends on a local system
SYNOPSIS
wuzzah [OPTIONS...]
DESCRIPTION
wuzzah is a program that just sits around and scans the utmpx entries
to watch when your friends log in and out. By default upon invocation,
wuzzah looks for the file ${HOME}/.wuzzah, and loads the list of
buddies contained therein (which are separated by newlines), and then
sits and watches. If no file is found, and no other readable file is
specified (see OPTIONS), wuzzah will attempt to just watch for whomever
the current uid maps, and failing that will just quit.
OPTIONS
-h, --help
an informative usage summary, though nothing you don’t see
here...
-a, --all-users
watches for all users on the system, period.
-c, --exec-cmd=CMD
execute CMD upon a login. NOTE: this is done with a call to
system(2), so you can do things like piping and whatever else
you can do with sh -c
-f, --buddy-file=FILE
use FILE as buddyfile. naturally FILE must be readable, and
consists of usernames, one to a line. optionally, these
usernames can be followed by a colon, and then a wuzzah command-
line to override wuzzah’s behavior for this specific user.
-F, --no-buddyfile
tells wuzzah to not bother loading any config files.
-i, --interval=NUM
sleep NUM seconds between each polling
-m, --message=STRING
use STRING as a message template to greet logged-in buddies.
See the section FORMATS for more information.
-n, --no-newline
don’t end the messages with newlines (normally does by default)
-o, --process-once
scan the login records once, then exit
-p, --process-current
by default wuzzah doesn’t message users who were already logged
in when started up. this option overrides such behavior and
messages them anyways (only useful with the -w/-c options)
-q, --silent
don’t message buddies when they log in (default).
-s, --status-message=STRING
use STRING as a template for displaying the status of people
logging in and out. See FORMATS for more information.
-u, --users=LIST
adds every user in LIST (a space/comma/colon separated list of
users) to the buddy list
-v, --version
the current version and copyright.
-w, --write-buddies
turns on messaging of buddies as they log in. NOTE: this can
get quite annoying rather quickly. tune in soon for a less
annoying solution
FORMATS
message templates can be defined as normal character strings,
interspersed with special format characters. format characters consist
of a ‘%’, followed by a character, which defines situation-specific
data. The current list of these characters is as follows:
a the alert character (’\a’)
b the name of the buddy who has logged in/out
d the date, currently in HH:MM:SS format
h and H
the remote hostname or IP address (respectively) of your buddy’s
login
l the line in/out on which the buddy is logged (typically,
something like /dev/pts/9 or /dev/ttyS0)
m whether or not you have just messaged your buddy (really only
useful for the -s option)
n an embedded newline character
o your buddy’s online status ("logged on" or "logged off")
u your own username, as can best be determined by the program.
EXAMPLES
a simple invocation:
username@machine$ wuzzah
(13:45:39) foo logged in on :0 (not messaging).
(13:45:39) bar logged in on pts/11 (not messaging).
Message from username@machine on pts/11 at 14:00 ...
(wuzzah) username says: "shoutout to my homie foo."
EOF
an example with a little more user customization:
username@machine$ wuzzah --message="hey, %b, it’s %u. nice to see you
at %d!"
and when foo logs in, foo will get a message like so:
Message from username@machine on pts/11 at 14:00 ...
hey, foo, it’s username. nice to see you at (14:00:00)!
EOF
FILES
~/.wuzzah
the default file containing the list of users to watch
