38 <blockquote>
39 <p>The <i>sccs</i> utility is a front end to the SCCS programs. It also includes the capability to run set-user-id to another user
40 to provide additional protection.</p>
41 <p>The <i>sccs</i> utility shall invoke the specified <i>command</i> with the specified <i>options</i> and <i>operands</i>. By
42 default, each of the <i>operands</i> shall be modified by prefixing it with the string <tt>"SCCS/s."</tt>.</p>
43 <p>The <i>command</i> can be the name of one of the SCCS utilities in this volume of POSIX.1-2024 (<a href=
44 "../utilities/admin.html"><i>admin</i></a>, <a href="../utilities/delta.html"><i>delta</i></a>, <a href=

51 <blockquote>
52 <p>The <i>sccs</i> utility shall conform to XBD <a href="../basedefs/V1_chap12.html#tag_12_02"><i>12.2 Utility Syntax
53 Guidelines</i></a> , except that <i>options</i> operands are actually options to be passed to the utility named by <i>command</i>.
54 When the portion of the command:</p>
55 <pre>
56 <i>command </i><b>[</b><i>options</i><tt> ... </tt><b>] [</b><i>operands</i><tt> ... </tt><b>]</b><tt>
57 </tt></pre>
58 <p>is considered, all of the pseudo-utilities used as <i>command</i> shall support the Utility Syntax Guidelines. Any of the other
59 SCCS utilities that can be invoked in this manner support the Guidelines to the extent indicated by their individual OPTIONS
60 sections.</p>
61 <p>The following options shall be supported preceding the <i>command</i> operand:</p>
62 <dl compact>
63 <dd></dd>
64 <dt><b>-d </b><i>path</i></dt>
65 <dd>A pathname of a directory to be used as a root directory for the SCCS files. The default shall be the current directory. The
66 <b>-d</b> option shall take precedence over the <i>PROJECTDIR</i> variable. See <b>-p</b>.</dd>
67 <dt><b>-p </b><i>path</i></dt>
68 <dd>A pathname of a directory in which the SCCS files are located. The default shall be the <b>SCCS</b> directory.
69 <p>The <b>-p</b> option differs from the <b>-d</b> option in that the <b>-d</b> option-argument shall be prefixed to the entire
70 pathname and the <b>-p</b> option-argument shall be inserted before the final component of the pathname. For example:</p>
71 <pre>
72 <tt>sccs -d /x -p y get a/b
73 </tt></pre>
74 <p>converts to:</p>
75 <pre>
76 <tt>get /x/a/y/s.b
77 </tt></pre>
78 <p>This allows the creation of aliases such as:</p>
79 <pre>
80 <tt>alias syssccs="sccs -d /usr/src"
81 </tt></pre>
82 <p>which is used as:</p>
83 <pre>
84 <tt>syssccs get cmd/who.c
85 </tt></pre></dd>
86 <dt><b>-r</b></dt>
87 <dd>Invoke <i>command</i> with the real user ID of the process, not any effective user ID that the <i>sccs</i> utility is set to.
88 Certain commands (<a href="../utilities/admin.html"><i>admin</i></a>, <b>check</b>, <b>clean</b>, <b>diffs</b>, <b>info</b>,
89 <a href="../utilities/rmdel.html"><i>rmdel</i></a>, and <b>tell</b>) cannot be run set-user-ID by all users, since this would allow
90 anyone to change the authorizations. These commands are always run as the real user.</dd>

117 <dl compact>
118 <dd></dd>
119 <dt><i>LANG</i></dt>
120 <dd>Provide a default value for the internationalization variables that are unset or null. (See XBD <a href=

124 <dd>If set to a non-empty string value, override the values of all the other internationalization variables.</dd>
125 <dt><i>LC_CTYPE</i></dt>
126 <dd>Determine the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as
127 opposed to multi-byte characters in arguments and input files).</dd>

132 <dd>Determine the location of messages objects and message catalogs.</dd>
133 <dt><i>PROJECTDIR</i></dt>
134 <dd><br>
135 Provide a default value for the <b>-d</b> <i>path</i> option. If the value of <i>PROJECTDIR</i> begins with a <slash>, it
136 shall be considered an absolute pathname; otherwise, the value of <i>PROJECTDIR</i> is treated as a user name and that user's

160 <p>The following pseudo-utilities shall be supported as <i>command</i> operands. All options referred to in the following list are
161 values given in the <i>options</i> operands following <i>command</i>.</p>
162 <dl compact>
163 <dd></dd>
164 <dt><b>check</b></dt>
165 <dd>Equivalent to <b>info</b>, except that nothing shall be printed if nothing is being edited, and a non-zero exit status shall be
166 returned if anything is being edited. The intent is to have this included in an "install" entry in a makefile to ensure that
167 everything is included into the SCCS file before a version is installed.</dd>
168 <dt><b>clean</b></dt>
169 <dd>Remove everything from the current directory that can be recreated from SCCS files, but do not remove any files being edited.
170 If the <b>-b</b> option is given, branches shall be ignored in the determination of whether they are being edited; this is
171 dangerous if branches are kept in the same directory.</dd>
172 <dt><b>create</b></dt>
173 <dd>Create an SCCS file, taking the initial contents from the file of the same name. Any options to <a href=
174 "../utilities/admin.html"><i>admin</i></a> are accepted. If the creation is successful, the original files shall be renamed by
175 prefixing the basenames with a comma. These renamed files should be removed after it has been verified that the SCCS files have
176 been created successfully.</dd>
177 <dt><b>delget</b></dt>
178 <dd>Perform a <a href="../utilities/delta.html"><i>delta</i></a> on the named files and then <a href=
179 "../utilities/get.html"><i>get</i></a> new versions. The new versions shall have ID keywords expanded and shall not be editable.
180 Any <b>-m</b>, <b>-p</b>, <b>-r</b>, <b>-s</b>, and <b>-y</b> options shall be passed to <a href=
181 "../utilities/delta.html"><i>delta</i></a>, and any <b>-b</b>, <b>-c</b>, <b>-e</b>, <b>-i</b>, <b>-k</b>, <b>-l</b>, <b>-s</b>,
182 and <b>-x</b> options shall be passed to <a href="../utilities/get.html"><i>get</i></a>.</dd>
183 <dt><b>deledit</b></dt>
184 <dd>Equivalent to <b>delget</b>, except that the <a href="../utilities/get.html"><i>get</i></a> phase shall include the <b>-e</b>
185 option. This option is useful for making a checkpoint of the current editing phase. The same options shall be passed to <a href=
186 "../utilities/delta.html"><i>delta</i></a> as described above, and all the options listed for <a href=
187 "../utilities/get.html"><i>get</i></a> above except <b>-e</b> shall be passed to <b>edit</b>.</dd>
188 <dt><b>diffs</b></dt>
189 <dd>Write a difference listing between the current version of the files checked out for editing and the versions in SCCS format.
190 Any <b>-r</b>, <b>-c</b>, <b>-i</b>, <b>-x</b>, and <b>-t</b> options shall be passed to <a href=
191 "../utilities/get.html"><i>get</i></a>; any <b>-l</b>, <b>-s</b>, <b>-e</b>, <b>-f</b>, <b>-h</b>, and <b>-b</b> options shall be
192 passed to <a href="../utilities/diff.html"><i>diff</i></a>. A <b>-C</b> option shall be passed to <a href=
193 "../utilities/diff.html"><i>diff</i></a> as <b>-c</b>.</dd>
194 <dt><b>edit</b></dt>
195 <dd>Equivalent to <a href="../utilities/get.html"><i>get</i></a> <b>-e</b>.</dd>
196 <dt><b>fix</b></dt>
197 <dd>Remove the named delta, but leave a copy of the delta with the changes that were in it. It is useful for fixing small compiler
198 bugs, and so on. The application shall ensure that it is followed by a <b>-r</b> <i>SID</i> option. Since <b>fix</b> does not leave
199 audit trails, it should be used carefully.</dd>
200 <dt><b>info</b></dt>
201 <dd>Write a listing of all files being edited. If the <b>-b</b> option is given, branches (that is, SIDs with two or fewer
202 components) shall be ignored. If a <b>-u</b> <i>user</i> option is given, then only files being edited by the named user shall be
203 listed. A <b>-U</b> option shall be equivalent to <b>-u</b><<i>current user</i>>.</dd>
204 <dt><b>print</b></dt>
205 <dd>Write out verbose information about the named files, equivalent to <i>sccs</i> <a href=
206 "../utilities/prs.html"><i>prs</i></a>.</dd>
207 <dt><b>tell</b></dt>
208 <dd>Write a <newline>-separated list of the files being edited to standard output. Takes the <b>-b</b>, <b>-u</b>, and
209 <b>-U</b> options like <b>info</b> and <b>check</b>.</dd>
210 <dt><b>unedit</b></dt>
211 <dd>This is the opposite of an <b>edit</b> or a <a href="../utilities/get.html"><i>get</i></a> <b>-e</b>. It should be used with
212 caution, since any changes made since the <a href="../utilities/get.html"><i>get</i></a> are lost.</dd>

281 <blockquote>
282 <p><i>sccs</i> and its associated utilities are part of the XSI Development Utilities option within the XSI option.</p>
283 <p>SCCS is an abbreviation for Source Code Control System. It is a maintenance and enhancement tracking tool. When a file is put
284 under SCCS, the source code control system maintains the file and, when changes are made, identifies and stores them in the file
285 with the original source code and/or documentation. As other changes are made, they too are identified and retained in the
286 file.</p>
287 <p>Retrieval of the original and any set of changes is possible. Any version of the file as it develops can be reconstructed for
288 inspection or additional modification. History data can be stored with each version, documenting why the changes were made, who
289 made them, and when they were made.</p>
