NAME

prs − print an SCCS file

SYNOPSIS

/usr/sccs/prs [ −d[dataspec] ] [ −r[SID] ] [ −e ] [ −l ] [ −a ] filename ...

DESCRIPTION

prs prints, on the standard output, parts or all of an SCCS file (see sccsfile(5)) 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, in which case each line is taken to be the name of an SCCS file or directory to be processed; non-SCCS files and unreadable files are silently ignored. 

OPTIONS

Options 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 DATA KEYWORDS) interspersed with optional user supplied text.

−r[SID]
Specifies 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. 

−eRequests information for all deltas created earlier than and including the delta designated via the −r option. 

−lRequests information for all deltas created later than and including the delta designated via the −r option. 

−aRequests 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 option is not specified, information for existing deltas only is provided. 

In the absence of the −d options, prs displays a default set of information consisting of: delta-type, release number and level number, date and time last changed, user-name of the person who changed the file, lines inserted, changed, and unchanged, the MR numbers, and the comments. 

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(5)) 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.

EXAMPLES

/usr/sccs/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

/usr/sccs/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:

/usr/sccs/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 option argument allowed to be used with the special case is the −a option.
