NAME
prs - print an SCCS file
SYNOPSIS
prs [-d dataspec] [-r[SID]] [-e] [-l] [-c date-time] [-a] files
DESCRIPTION
prs prints, on the standard output, parts or all of an SCCS file [see
sccsfile(4)] in a user-supplied format. If a directory is named, prs
behaves as though each file in the directory were specified as a named
file, except that non-SCCS files (last component of the path name does
not begin with s.), and unreadable files are silently ignored. If a name
of - is given, the standard input is read; each line of the standard
input is taken to be the name of an SCCS file or directory to be
processed; non-SCCS files and unreadable files are silently ignored.
Arguments to prs, which may appear in any order, consist of keyletter
arguments, and file names.
All the described keyletter arguments apply independently to each named
file:
-d[dataspec] Used to specify the output data specification. The
dataspec is a string consisting of SCCS file data
keywords (see DATA KEYWORDS) interspersed with
optional user supplied text.
-r[SID] Used to specify the SCCS IDentification (SID) string
of a delta for which information is desired. If no
SID is specified, the SID of the most recently
created delta is assumed.
-e Requests information for all deltas created earlier
than and including the delta designated via the -r
keyletter or the date given by the -c option.
-l Requests information for all deltas created later
than and including the delta designated via the -r
keyletter or the date given by the -c option.
-c [date-time] The cutoff date-time -c[date-time]] is in the form:
YY[MM[DD[HH[MM[SS]]]]]
Units omitted from the date-time default to their
maximum possible values; that is, -c7502 is
equivalent to -c750228235959. The values of 00-38
for YY indicate 2000-2038. YY values between 39 and
69 are not permitted. Any number of non-numeric
characters may separate the various 2-digit pieces of
the cutoff date in the form: "-c77/2/2 9:22:25".

-a Requests printing of information for both removed,
i.e., delta type = R, [see rmdel(1)] and existing,
i.e., delta type = D, deltas. If the -a keyletter is
not specified, information for existing deltas only
is provided.
DATA KEYWORDS
Data keywords specify which parts of an SCCS file are to be retrieved and
output. All parts of an SCCS file [see sccsfile(4)] have an associated
data keyword. There is no limit on the number of times a data keyword
may appear in a dataspec.
The information printed by prs consists of: (1) the user-supplied text;
and (2) appropriate values (extracted from the SCCS file) substituted for
the recognized data keywords in the order of appearance in the dataspec.
The format of a data keyword value is either Simple (S), in which keyword
substitution is direct, or Multi-line (M), in which keyword substitution
is followed by a carriage return.
User-supplied text is any text other than recognized data keywords.
A tab is specified by \t and carriage return/new-line is specified by \n.
The default data keywords are:
":Dt:\t:DL:\nMRs:\n:MR:COMMENTS:\n:C:"

EXAMPLES
prs -d"Users and/or user IDs for :F: are:\n:UN:" s.file
may produce on the standard output:
Users and/or user IDs for s.file are:
xyz
131
abc

prs -d"Newest delta for pgm :M:: :I: Created :D: By :P:" -r s.file
may produce on the standard output:
Newest delta for pgm main.c: 3.7 Created 77/12/1 By cas
As a special case:
prs s.file
may produce on the standard output:
D 1.1 77/12/1 00:00:00 cas 1 000000/00000/00000
MRs:

bl79-54321
COMMENTS:
this is the comment line for s.file initial delta
for each delta table entry of the ``D'' type. The only keyletter
argument allowed to be used with the special case is the -a keyletter.
