prs(1) General Commands Manual prs(1)
Name
prs - display information from an SCCS file
Syntax
prs [-d[dataspec]] [-r[SID]] [-e] [-l] [-a] files
Description
The command prints on the standard output all or parts of an SCCS file in a user supplied format. For further information, see If a direc-
tory is named, 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 which may appear in any order, consist of keyletter arguments, and file names.
Options
All the described keyletter arguments apply independently to each named file:
-a Displays printing of information for both removed and existing deltas. For example, removed delta type = R, and exist-
ing delta type = D. For further information, see If the -a keyletter is not specified, information is provided only
for existing deltas.
-d[dataspec] Displays information specified by dataspec. The dataspec is a string consisting of SCCS file data keywords (see DATA
KEYWORDS) interspersed with optional user-supplied text.
-e Displays information for all deltas created earlier than and including the delta designated by the -r keyletter.
-l Displays information for all deltas created later than and including the delta designated by the -r keyletter.
-r[SID] Indicates delta version number. If no SID is specified, the SID of the most recently created delta is assumed.
Data Keywords
Data keywords specify which parts of an SCCS file are to be retrieved and printed on the standard output. All parts of an SCCS file have
an associated data keyword. For further information, see There is no limit on the number of times a data keyword may appear in a dataspec.
The information printed by consists of the user supplied text and the 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 and carriage return/new-line is specified by
.

Examples
The following is an example of a command line and what it produces on the standard output:
prs -d"Users and/or user IDs for :F: are:
:UN:" s.file
Users and/or user IDs for s.file are:
xyz
131
abc
This is another example and its output.
prs -d"Newest delta for pgm :M:: :I: Created :D: By :P:" -r s.file
Newest delta for pgm main.c: 3.7 Created 77/12/1 By case
This is an example of a special case:
prs s.file
This is what it 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.
