PRS(1) PRS(1) 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 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) 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 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 -c[date-time]] is in the form: YY[MM[DD[HH[MM[SS]]]]] Units omitted from the date-time default to their maximum possible values; that is, -c7502 is equivalent to -c750228235959. The values of 00-38 for YY indicate 2000-2038. YY values between 39 and 69 are not permitted. Any number of non-numeric characters may separate the various 2-digit pieces of the cutoff date in the form: "-c77/2/2 9:22:25". -a Requests printing of information for both removed, i.e., delta type = R, [see rmdel(1)] and existing, i.e., delta type = D, deltas. If the -a keyletter is not specified, information for existing deltas only is provided. 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. A tab is specified by \t and carriage return/new-line is specified by \n. The default data keywords are: ":Dt:\t:DL:\nMRs:\n:MR:COMMENTS:\n:C:" TABLE 1.
