SYNTAX
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 treats each file in the directory 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] Specifies the SCCSIDentification (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.
information for all deltas created earlier
than and including the delta designated via
the -r keyletter or the date given by the -c
option. information for all deltas created
later than and including the delta designated
via the -r keyletter or the date given by the
-c option. Cutoff date-time, in the form:
YY[MM[DD[HH[MM[SS]]]]]
-c[date-time] Units omitted from the date-time 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". 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. A data keyword may
appear in a dataspec any number of times.
Prs prints: (1) the user-supplied text; and (2) appropriate
values (extracted from the SCCS file) substituted for the
recognized data keywords as they appear in the dataspec. The
format of a data keyword value is either Simple SCCS, in which
keyword substitution is direct, or Multi-line , 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:
bl78-12345
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.
