Name
prs - print an SCCS file
Syntax
prs [-d[dataspec]] [-r[SID]] [-e] [-l] [-c[date-time]] [-a]
files
Description
The prs command prints, on the standard output, parts or all
of an SCCS file (see sccsfile(F)) 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[cutoff] 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. 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".
The -c option must be used with the -e
or -l option.
-a Requests printing of information for
both removed, i.e., delta type = R, (see
rmdel(CP)) 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(F)) 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: (C) the user-
supplied text; and (S) 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 Multiline (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:
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.
