Archive-name: pegboard
[ I tweaked the Makefile and added the -DBSD stuff; looks like the
original was for Xenix (/etc/default?) /r$ ]
This program can be used to keep track of who is in or out of the
office, and when they are due back. To be useful, people have to
USE it, but this is true of traditional pegboards as well. People
here find it friendly enough and pretty much keep the pegboard updated.

XPeg is an online pegboard. It is used to see if someone is in or
Xout of the office and when they are expected back. Do "make install"
Xafter you get it to compile.
X
XThere is at least 1 incompatibilty problem you may encounter, fcntl
Xtype locking is used. The functions are "pblock()" and "pbunlock()"
Xin "pegio.c". "getopts()" is required, if you don't have it you can
Xget it from an archive site. You will want yacc if you are going to
Xdo any major additions to the source. There is nothing in the makefile
Xto install the man page, you will have to do that by hand.
X
XYou may find it useful for other things too, the verify "-v" option
Xhas possibilities, eg.:
X--------
X#
X# Mail list of meeting dates and times to users
X#
XSDATE="Monday 8" # The first meeting, next Monday at 8:00A
XUSERLIST=administrators
XSUBJECT=Meetings
XMESSAGE="Future meeting dates and times, please don't be late:\n"
X
X{
X echo $MESSAGE
X #
X # 6 monthly meetings, each on the day given in SDATE
X for OFFSET in 0 4 8 12 16 20
X do
X peg -v $SDATE + ${OFFSET}w
X done
X} | mail -s $SUBJECT $USERLIST
X--------
X
XPeg needs some way of recognizing dates that are holidays, so they can
Xbe skipped when the "-t" option is given. This is not covered in the
Xcurrent implementation. If someone cares to add this feature please
Xsend us the additions.
X
XThis was my first bout with yacc, and I'm sure there are better ways
Xto do what I did. Constructive criticism is welcome, send to:

X.SH DESCRIPTION
X.I peg
Xmaintains a list of users who have logged off the system (a
X.I pegboard
X), and dates and times of when they intend return to the site.
XThe default action when no arguments are given is to print the
Xpegboard contents on standard output.
XThe -u option may be used to print the pegboard entry for a
Xspecific user.
X.P
XContext of arguments is dependent on their format.
XArguments that contain a "/" character are taken to be a date,
Xand one or two "/"'s may be present.
XIn the case of one, "MM/DD" is taken as a month and a day.
X"YY/MM/DD" is taken as year month and day.
X.P
XArguments that contain a ":" are taken as a time, and only one
X":" may be present.
X"HH:MM" is taken as hour and minute.
XA single argument is taken to be an hour in the current day.
XHours are in 24 hour format, unless the argument is suffixed with the
Xletter "p", in which case the time is assumed to be after 12 noon.
XFinally, a full date and time specification may be given by
Xproviding both arguments, in either order.
X.P
XNumeric arguments may be preceded by a "+", in this case
Xthe argument is taken as a "relative" quantity of time.
XThere may be an optional modifier after relative arguments,
Xlegal modifiers are "m", "h", "d" and "w".
X.TP
X.BR m
Xthe offset is taken as a number of minutes from the current time
X.TP
X.BR h
Xthe offset is taken as a number of hours from the current time (default)
X.TP
X.BR d
Xthe offset is taken as a number of days from the current date
X.TP
X.BR w
Xthe offset is taken as a number of weeks from the current date
X.P
XIf a modifier is not given and the argument is in "+n" format,
X"n" is assumed to be a number of hours from the current time
X(the h modifier is redundant).
X.P
XPeg recognizes names of days and months as well.
XMonth names must be followed by a day, ie. Sept 12.
XThe next occurrence of a day or month/day combination specified is assumed.
XSo specifying Tue on a Wednesday results in Tuesday of next week being
Xthe specified day.
XSimilarly, giving a month/day that has already gone by results in that day
Xin the next year being the specified date.
X.P
XAny (reasonable) number of arguments may be given.
XThe effect of multiple arguments is additive, so specifying more
Xthan one absolute date or time will not likely yield expected results.
XMixing one absolute date with some number of relative type arguments
Xhas the effect of adding the relative arguments to the absolute.
X.P
XAfter the pegboard is updated (and the -n, -x, -i or -v options
Xwere not given),
Xall processes in the process group are sent the signal SIGKILL.
X.P
X.I "peg"
Xshould be run with the "-x" option in the system
X.I .profile
Xso that each time the a user logs onto the system their pegboard entry
Xis expunged.
X.P
X.SH EXAMPLES

X.BR "peg 99/1/12 14:00"
XLog off and peg invoking user to be back January 12, 1999, at 2:00 pm
X.TP 20
X.BR "peg 2:00p 99/1/12"
XSame as above
X.TP 20
X.BR "peg 3/10"
XLog off and peg invoking user to be back March 10 at the current time.
XIf March 10th has passed then March 10th next year is assumed.
X.TP 20
X.BR "peg +2"
XLog off and peg invoking user to be back 2 hours from current time
X.TP 20
X.BR "peg 2:00p"
XLog off and peg invoking user to be back at 2pm today
X.TP 20
X.BR "peg +45m"
XLog off and peg invoking user to be back 45 minutes from the current time
X.TP 20
X.BR "peg -t +3d"
XLog off and peg invoking user to be back 3 days from current date at the
Xtime found in the ".pegrc" file in their home directory
X.TP 20
X.BR "peg -t"
XLog off and and peg invoking user to be back on the next day and time that has
Xan entry in the ".pegrc" file.
XDays that have no entry will be skipped over.
X.TP 20
X.BR "peg -t 14"
XLog off and peg invoking user to be back 2:00 pm on the next day specified
Xin their
X.I .pegrc
Xfile.
X.TP 20
X.BR "peg -v +1 +1 +1"
Xprint what time it will be in three hours

X.P
XThis variable specifies the directory that peg uses for the pegboard.
XEach machine associated with a common pegboard should have

Xthe PEGDIR variable.

X.P
XUsed to specify tty's that override the action of the
X.I "-x"

XIf peg is invoked from a tty that is listed thusly in
X.I "/etc/default/peg"
Xthen the program exits without updating the pegboard.
XPorts that are connected to modems should be listed in this manner.
X.TP 24
X.BR PEGDIR/pegboard.a*
Xholds a copy of the pegboard when update is in progress
X.TP 24
X.BR $HOME/.pegrc
Xdefault start time of day and days of week
X.TP 24
X.BR /etc/passwd
XUsernames etc. are extracted from this file.
XThe users name is assumed to be in the "gecos" field of the passwd entry
X.SH NOTES
XThe pegboard is maintained using
X.I "user id"
Xnumbers.
X.P
XOnly the first 3 letters of day and month names are significant.
X.P
XIf the real user id of the invoking user is 0 and the
X.I "-u"
Xcommand line option
Xis given then the specified users pegboard entry is updated to the date
Xgiven.
XIf the invoking user id is 0 and both the
X.I "-u"
Xand
X.I "-x"
Xoptions are given then the user name specified as the
X.I "-u"
Xargument is removed from the pegboard.
X.P
XWeek and month names etc. in the command line and tokens and variable names
Xin the
X.I ".pegrc"
Xand
X.I "/etc/default/peg"
Xfiles are
X.BR not
Xcase sensitive.
X.I Arguments
Xin the
X.I /etc/default/peg
Xand
X.I .pegrc
Xfiles
X.BR are
Xcase sensitive.
X.P
XComments are restricted to 64 characters, and must be whitespace or printable.
XThey are truncated to 32 characters in the short form to avoid
Xmessing up screens (assuming 80 column ttys).
XThe complete comment may be read by invoking with the "-l" option.
X.P
XIf no PEGDIR variable is found in the
X.I /etc/default/peg
Xfile then the default directory used is
X.I /usr/spool.

XThis program can be used to keep track of who is in or out of the
Xoffice, and when they are due back. To be useful, people have to
XUSE it, but this is true of traditional pegboards as well. People
Xhere find it friendly enough and pretty much keep the pegboard updated.
