NAME
prs - print an SCCS file
SYNOPSIS
prs [ -d[dataspec]] [ -r[SID]] [-e] [-l] [ -c[date-time]] [-a] file ...
DESCRIPTION
prs prints, on the standard output, part or all of an SCCS (Source Code
Control System) file in a user-supplied format. If you name a directory,
prs behaves as though each file in the directory is specified as a named
file, except that it silently ignores non-SCCS and unreadable files. If
a dash (-) is given in place of a filename, prs reads the standard input,
taking each line to be the name of an SCCS file or directory to be
processed. Options to prs may appear in any order. Each argument
applies independently to each named file.
OPTIONS
-d[dataspec]Specify the output data specification. The dataspec is a
string consisting of SCCS file data keywords interspersed
with optional user-supplied text.
-r[SID] Specify the SCCS Identification (SID) string of the delta for
which information is desired. If you do not specify an SID,
then prs assumes the SID to be that of the most recently
created delta.
-e Request 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 Request 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]
Specify date-time as cutoff for requesting information. This
cutoff date-time appears in the following form:
YY[MM[DD[HH[MM[SS]]]]]
Units omitted from the date-time default to their maximum
possible values; that is, -c8502 is equivalent to
-c850228235959. Any number of non-numeric characters may
separate the various two-digit pieces of the cutoff date in
the following form:
-c85/2/2 9:22:25.
-a Request printing of information for both removed (delta type
= R) and existing (delta type = D) deltas. Refer to rmdel(1)
for more information. If you do not specify the -a
keyletter, prs provides information only on existing deltas.
DATA KEYWORDS
Data keywords specify those parts of an SCCS file to be retrieved and
output. All parts of an SCCS file have an associated data keyword.
Refer to sccsfile(4) for more information about the structure of these
file types. There is no limit on the number of times a data keyword may
appear in a dataspec.
prs prints the user-supplied text, and 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 a carriage return/newline is specified by
\n. The default data keywords are:
":Dt:\t:DL:\nMRs:\n:MR:COMMENTS:\n:C:"

Users and/or user IDs for s.file are:

A simple command line without options, such as prs s.file, may produce
the following on the standard output, for each delta table entry of the
"D" type:
