prs -- print an SCCS file

Syntax

prs [-d[dataspec]] [-r[SID]] [-e] [-l] [-c[date-time]] [-a] files
prs -

Description

The prs command prints, on standard output, parts or all of an SCCS file (see sccsfile(FP)) 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 and unreadable files are silently ignored. If a name of ``-'' is given, the standard input is read; each line of 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 may appear in any order. All the described 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 option 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 option or the date given by the -c option.

-c[date-time]
The cutoff [date-time] is in the form:

YY[MM[DD[HH[MM[SS]]]]]

For the YY component, year within century. When a century is not otherwise specified, values in the range 69-99 refer to years in the twentieth century (1969 to 1999 inclusive); values in the range 00-68 refer to years in the twenty-first century (2000 to 2068 inclusive).

Units omitted from the [date-time] default to their maximum possible values; that is, -c9502 is equivalent to -c950228235959. The -c option must be used with the -e or -l option.

Any number of non-numeric characters may separate the various two-digit pieces of the cutoff date in the form:

-c"94/12/2 9:22:25"


-a
Requests printing of information for both removed (delta type R) and existing (delta type D) deltas (see rmdel(CP). If -a is not specified, information is provided for existing deltas only.

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(FP)) 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 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 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 94/12/1 By cas

As a special case: prs s.file may produce on the standard output for each delta table entry of the ``D'' type. For example:

D 1.1 94/12/1 00:00:00 cas 1 000000/00000/00000
MRs:
bl8-12345
bl9-54321
COMMENTS:
this is the comment line for s.file initial delta

The only option allowed to be used with the special case is -a.

Files
