User Commands sccs-prs(1)
NAME
sccs-prs, prs - display selected portions of an SCS history
SYNOPSIS
prs [-ael] [-cdate-time] [-ddataspec] [-rsid] s.filename...
DESCRIPTION
The prs utility displays part or all of the SCS file (see
sccsfile(4)) in a user supplied format.
If a directory name is used in place of the s.filename argu-
ment, the prs command applies to all s.files in that direc-
tory. Unreadable s.files produce an error; processing con-
tinues with the next file (if any). The use of `-' as the
s.filename argument indicates that the names of files are to
be read from the standard input, one s.file per line.
OPTIONS
In the absence of options, prs displays the delta table
(version log). In the absence of -d, or -l, prs displays the
entry for each delta indicated by the other options.
-a Includes all deltas, including those marked
as removed (see sccs-rmdel(1)).
-e Requests information for all deltas created
earlier than, and including, the delta indi-
cated with -r or -c.
-l Requests information for all deltas created
later than, and including, the delta indi-
cated with -r or -c.
-cdate-time Either options -eor -lmust be used with this
option. -cdate-time displays information on
the deltas checked in either prior to and
including the date and time indicated by the
date-time argument (option -e); or later than
and including the date and time indicated
(option -l). date-time takes the form:
yy[mm[dd[hh[mm[ss]
Units omitted from the indicated date and
time default to their maximum possible
values; that is -c7502 is equivalent to
-c750228235959. Any number of non-numeric

characters may separate the various 2 digit
components. If white-space characters occur,
the date-time specification must be quoted.
Values of yy in the range 69-99 refer to the
twentieth century. Values in the range of
00-68 refer to the twenty-first century.
-ddataspec Produce a report according to the indicated
data specification. dataspec consists of a
(quoted) text string that includes embedded
data keywords of the form: `:key:' (see Data
Keywords, below). prs expands these keywords
in the output it produces. To specify a TAB
character in the output, use \t; to specify a
NEWLINE in the output, use \n.
-rsid Specifies the SCS delta ID (SID) of the
delta for which information is desired. If no
SID is specified, the most recently created
delta is used.
USAGE
Usage of prs is described below.
Data Keywords
Data keywords specify which parts of an SCS file are to be
retrieved. All parts of an SCS file (see sccsfile(4)) have
an associated data keyword. A data keyword may appear any
number of times in a data specification argument to -d.
These data keywords are listed in the table below:

:A: a format for the what string: N/A :Z::Y: :M: :I::Z: S
:B: branch number D nnnn S
