prs(1) — USER COMMANDS
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 prints the files in that directory, except the non-SCCS files (last component of the path name does not begin with s.) and unreadable files. 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. prs silently ignores non-SCCS files and unreadable files.
Arguments to prs, which may appear in any order, consist of keyletter arguments and file names.
The keyletter arguments apply independently to each named file:
−d[dataspec] Specifies the output data specification. The dataspec is a string consisting of SCCS file data keywords (see the DATA KEYWORDS section) interspersed with optional user-supplied text.
−r[SID] Specifies the SCCS identification (SID) string of a delta for which information is desired. The default is the top delta.
−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 in the form:
YY[MM[DD[HH[MM[SS]]]]]
Units omitted from the date−time default to their maximum possible values; for example, −c7502 is equivalent to -c750228235959. Any number of non-numeric characters may separate the fields of the cutoff date; for example, "−c77/2/2 9:22:25".
−a Requests printing of information for both removed, that is, delta type = R, [see rmdel(1)] and existing, that is, delta type = D, deltas. If the −a keyletter is not specified, information for existing deltas only is provided.
DATA KEYWORDS
Data keywords specify those parts of an SCCS file that 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:

EXAMPLES
The command
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
The command
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
The default case:
prs s.file
produces 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.
