37 <blockquote>
38 <p>The <i>sact</i> utility shall inform the user of any impending deltas to a named SCCS file by writing a list to standard output.
39 This situation occurs when <a href="../utilities/get.html"><i>get</i></a> <b>-e</b> has been executed previously without a
40 subsequent execution of <a href="../utilities/delta.html"><i>delta</i></a>, <a href="../utilities/unget.html"><i>unget</i></a>, or
41 <a href="../utilities/sccs.html"><i>sccs</i></a> <b>unedit</b>.</p>

48 <blockquote>
49 <p>The following operand shall be supported:</p>
50 <dl compact>
51 <dd></dd>
52 <dt><i>file</i></dt>
53 <dd>A pathname of an existing SCCS file or a directory. If <i>file</i> is a directory, the <i>sact</i> utility shall behave as
54 though each file in the directory were specified as a named file, except that non-SCCS files (last component of the pathname does
55 not begin with <b>s.</b>) and unreadable files shall be silently ignored.
56 <p>If exactly one <i>file</i> operand appears, and it is <tt>'-'</tt>, the standard input shall be read; each line of the standard
57 input shall be taken to be the name of an SCCS file to be processed. Non-SCCS files and unreadable files shall be silently
58 ignored.</p>

79 variables used to determine the values of locale categories.)</dd>

81 <dd>If set to a non-empty string value, override the values of all the other internationalization variables.</dd>
82 <dt><i>LC_CTYPE</i></dt>
83 <dd>Determine the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as
84 opposed to multi-byte characters in arguments and input files).</dd>
85 <dt><i>LC_MESSAGES</i></dt>
86 <dd><br>
87 Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error.</dd>
