PRS(1) — HP-UX
NAME
prs − print and summarize an SCCS file
SYNOPSIS
prs [−d[dataspec]] [−r[SID]] [−e] [−l] [−c] [−a] file ...
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 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 prs, which may appear in any order, consist of keyletter arguments, and file names.
All the described keyletter 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 below) 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. If an SID is specified, it must agree exactly with an SID in the file (that is, the SID structure used by get(1) does not work here).
−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[cutoff] Cutoff date-time, in the form
YY[MM[DD[HH[MM[SS]]]]]
Units omitted from the date-time default to their maximum possible values. Thus, −c7502 is equivalent to −c750228235959. One or more non-numeric characters can be used to separate the various 2-digit segments of the cutoff date (for example -c77/2/2 9:22:25).
−a Requests printing of information for both removed, i.e., 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.
If no option letters (or only −a) are given, prs prints the file name using the default dataspec and the −e option. This produces information on all deltas.
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(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. Escapes may be used as follows:
tab\t
new-line\n
colon\:
backspace\b
carriage-return\r
form feed\f
backslash\\
single quote\´
The default dataspec is:
":Dt:\t:DL:\nMRs:\n:MR:COMMENTS:\n:C:"

If no option letters (or only -a) are given, prs prints the file name, using the default dataspec, and the -e option; thus, information on all deltas is produced.
DIAGNOSTICS
Use help(1) for explanations.
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 77/12/1 By cas
As a special case (when no specifications for selecting or printing are given)
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 keyletter argument allowed to be used with the special case is the −a keyletter.
