prs(1)prs(1)NAMEprs - print and summarize an SCCS file
SYNOPSIS
dataspec] [SID]] cutoff] file ...
DESCRIPTION
The command 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, 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 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 pro‐
cessed; non-SCCS files and unreadable files are silently ignored. A on
the command line implies that all following arguments are file/direc‐
tory names.
Arguments to which can appear in any order, consist of options and file
names.
Options
All of the described options apply independently to each named file:
Used to specify the output data specification.
dataspec is a string consisting of SCCS file data
keywords (see Data Keywords below) interspersed
with optional user-supplied text.
Used to specify the
SCCS IDentification (SID) string of a delta for
which information is desired. If no SID is spec‐
ified, 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 does not work here —
see get(1)).
Requests information for all deltas created
than and including the delta designated via the
option or the date given by the option.
Requests information for all deltas created
than and including the delta designated via the
option or the date given by the option.
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, is equivalent to
One or more non-numeric characters can be used to
separate the various 2-digit segments of the cut‐
off date (for example
For 2-digit year input the following interpreta‐
tion is taken:
Requests printing of information for both removed,
that is, delta type = R, (see rmdel(1)) and
existing, that is, delta type = D, deltas. If
the option is not specified, information is pro‐
vided for existing deltas only.
If no option letters (or only are given, prints the file name using the
default dataspec and the 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 asso‐
ciated data keyword. There is no limit on the number of times a data
keyword can appear in a dataspec.
The information printed by 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 (S), in which
keyword substitution is direct, or (M), in which keyword substitution
is followed by a carriage return.
User-supplied text is any text other than recognized data keywords.
Escapes can be used as follows:
backslash \\ form feed \f
backspace \b new-line \n
carriage return \r single quote \'
colon \: tab \t
The default dataspec is:

If no option letters (or only are given, prints the file name, using
the default dataspec, and the option; thus, information on all deltas
is produced.
EXTERNAL INFLUENCES
Environment Variables
determines the interpretation of dataspec as single and/or multi-byte
characters.
determines the language in which messages are displayed.
If or is not specified in the environment or is set to the empty
string, the value of is used as a default for each unspecified or empty
variable. If is not specified or is set to the empty string, a default
of "C" (see lang(5)) is used instead of If any internationalization
variable contains an invalid setting, behaves as if all international‐
ization variables are set to "C". See environ(5).
International Code Set Support
Single-byte and multi-byte character code sets are supported.
DIAGNOSTICS
See sccshelp(1) for explanations.
