NAME
prs - Displays an SCCS file
SYNOPSIS
prs [-d[dataspec]] [-r[SID]] [-e] [-l] [-c[cutoff]] [-a] files
DESCRIPTION
The prs command displays, on stdout, parts or all of an SCCS file (see
sccsfile) 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 pathname does not begin
with s.), and unreadable files are silently ignored. If a name of - is
given, stdin is read; each line of stdin 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 flag
arguments, and filenames.
All the described flag 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 with the -r flag or the
date given by the -c flag.
-l Requests information for all deltas created later than and
including the delta designated with the -r flag or the
date given by the -c flag.
-c [cutoff] The cutoff date-time -c[cutoff] is in the form:
YY[MM[DD[HH[MM[SS]]]]]
Units omitted from the cutoff default to their maximum
possible values; that is, -c7502 is equivalent to -
c750228235959. 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 displaying of information for both removed, that
is, delta type = R, (see rmdel) and existing, that is,
delta type = D, deltas. If the -a flag 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) have an associated data
keyword. There is no limit on the number of times a data keyword may
appear in a dataspec.
The information displayed 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/newline is specified by \n.
The default data keywords are:

EXAMPLES
1.
prs -d"Users and/or user IDs for :F: are:\n:UN:" s.file
may produce on stdout:
Users and/or user IDs for s.file are:
xyz
131
abc
2.
prs -d"Newest delta for pgm :M:: :I: Created :D: By :P:" -r s.file
4 Intergraph Corporation - 2/94
prs(1) CLIX prs(1)
may produce on stdout:
Newest delta for pgm main.c: 3.7 Created 77/12/1 By cas
3. As a special case:
prs -s.file
may produce on stdout:
D 1.1 77/12/1 00:00:00 cas 1 000000/00000/00000
MRs:
bl78-12345
bl79-54321
4. this is the comment line for s.file initial delta for each delta table
entry of the ``D'' type. The only flag argument allowed to be used
with the special case is the -a flag.
