6 prs - print an SCCS file (DEVELOPMENT)
7
9 prs [-a][-d dataspec][-r[SID]] file...
10 prs [ -e| -l] -c cutoff [-d dataspec] file...
14 prs [ -e| -l] -r[SID][-d dataspec]file...
18
21 The prs utility shall write to standard output parts or all of an SCCS
22 file in a user-supplied format.
23
25 The prs utility shall conform to the Base Definitions volume of
26 IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines, except
27 that the -r option has an optional option-argument. This optional
28 option-argument cannot be presented as a separate argument. The follow‐
29 ing options shall be supported:
30 -d dataspec
32 Specify the output data specification. The dataspec shall be a
33 string consisting of SCCS file data keywords (see Data Keywords
34 ) interspersed with optional user-supplied text.
35 -r[SID]
37 Specify the SCCS identification string (SID) of a delta for
38 which information is desired. If no SID option-argument is spec‐
39 ified, the SID of the most recently created delta shall be
40 assumed.
41 -e Request information for all deltas created earlier than and
43 including the delta designated via the -r option or the date-
44 time given by the -c option.
45 -l Request information for all deltas created later than and
47 including the delta designated via the -r option or the date-
48 time given by the -c option.
49 -c cutoff
51 Indicate the cutoff date-time, in the form:
52 YY[MM[DD[HH[MM[SS]]]]]
55 For the YY component, values in the range [69,99] shall refer to years
57 1969 to 1999 inclusive, and values in the range [00,68] shall refer to
58 years 2000 to 2068 inclusive.
59 Note:
61 It is expected that in a future version of IEEE Std 1003.1-2001
62 the default century inferred from a 2-digit year will change.
63 (This would apply to all commands accepting a 2-digit year as
64 input.)
65 No changes (deltas) to the SCCS file that were created after the speci‐
68 fied cutoff date-time shall be included in the output. Units omitted
69 from the date-time default to their maximum possible values; for exam‐
70 ple, -c 7502 is equivalent to -c 750228235959.
71 -a Request writing of information for both removed-that is, delta
73 type= R (see rmdel )- and existing-that is, delta type= D,-
74 deltas. If the -a option is not specified, information for
75 existing deltas only shall be provided.
76
79 The following operand shall be supported:
80 file A pathname of an existing SCCS file or a directory. If file is a
82 directory, the prs utility shall behave as though each file in
83 the directory were specified as a named file, except that non-
84 SCCS files (last component of the pathname does not begin with
85 s.) and unreadable files shall be silently ignored.
86 If exactly one file operand appears, and it is '-' , the standard input
88 shall be read; each line of the standard input shall be taken to be the
89 name of an SCCS file to be processed. Non-SCCS files and unreadable
90 files shall be silently ignored.
91
94 The standard input shall be a text file used only when the file operand
95 is specified as '-' . Each line of the text file shall be interpreted
96 as an SCCS pathname.
97
99 Any SCCS files displayed are files of an unspecified format.
100
102 The following environment variables shall affect the execution of prs:
103 LANG Provide a default value for the internationalization variables
105 that are unset or null. (See the Base Definitions volume of
106 IEEE Std 1003.1-2001, Section 8.2, Internationalization Vari‐
107 ables for the precedence of internationalization variables used
108 to determine the values of locale categories.)
109 LC_ALL If set to a non-empty string value, override the values of all
111 the other internationalization variables.
112 LC_CTYPE
114 Determine the locale for the interpretation of sequences of
115 bytes of text data as characters (for example, single-byte as
116 opposed to multi-byte characters in arguments and input files).
117 LC_MESSAGES
119 Determine the locale that should be used to affect the format
120 and contents of diagnostic messages written to standard error.
121 NLSPATH
123 Determine the location of message catalogs for the processing of
124 LC_MESSAGES .
125
128 Default.
129
131 The standard output shall be a text file whose format is dependent on
132 the data keywords specified with the -d option.
133 Data Keywords
135 Data keywords specify which parts of an SCCS file shall be retrieved
136 and output. All parts of an SCCS file have an associated data keyword.
137 A data keyword may appear in a dataspec multiple times.
138 The information written by prs shall consist of:
140 1. The user-supplied text
142 2. Appropriate values (extracted from the SCCS file) substituted for
144 the recognized data keywords in the order of appearance in the
145 dataspec
146 The format of a data keyword value shall either be simple ( 'S' ), in
148 which keyword substitution is direct, or multi-line ( 'M' ).
149 User-supplied text shall be any text other than recognized data key‐
151 words. A <tab> shall be specified by '\t' and <newline> by '\n' . When
152 the -r option is not specified, the default dataspec shall be:
153 :PN::\n\n
156 and the following dataspec shall be used for each selected delta:

275 Delta for pgm main.c: 3.7 - 77/12/01 By cas
278 3. As a special case:
280 prs s.file
283 might write to standard output:

293 COMMENTS:
294 this is the comment line for s.file initial delta

296 for each delta table entry of the D type. The only option allowed to be
298 used with this special case is the -a option.
