file-editing activity (<b>DEVELOPMENT</b>)</blockquote><h4><a name = "tag_001_014_1936"> </a>SYNOPSIS</h4><blockquote><pre><code>sact <i>file</i>...</code></pre></blockquote><h4><a name = "tag_001_014_1937"> </a>DESCRIPTION</h4><blockquote>The<i>sact</i>utility informs the user of any impending deltas to a named SCCS fileby writing a list to standard output.This situation occurs when<i><a href="get.html">get</a></i><b>-e</b>has been executed previously without a subsequentexecution of<i><a href="delta.html">delta</a></i>.</blockquote><h4><a name = "tag_001_014_1938"> </a>OPTIONS</h4><blockquote>None.</blockquote><h4><a name = "tag_001_014_1939"> </a>OPERANDS</h4><blockquote>The following operand is supported:<dl compact><dt><i>file</i><dd>A pathname of an existing SCCS file or a directory.If<i>file</i>is a directory,<i>sact</i>behaves as though each file in the directory werespecified as a named file,except that non-SCCS files(last component of the pathname does not begin withs.)and unreadable files are silently ignored.If a single instance<i>file</i>is specified as -,the standard input is read;each line of the standard input is taken to be the name of an SCCS fileto be processed.Non-SCCS files and unreadable files are silently ignored.</dl></blockquote><h4><a name = "tag_001_014_1940"> </a>STDIN</h4><blockquote>The standard input is a text file used only when the<i>file</i>operand is specified as -.Each line of the text file is interpreted as an SCCS pathname.</blockquote><h4><a name = "tag_001_014_1941"> </a>INPUT FILES</h4><blockquote>Any SCCS files interrogated are files of an unspecified format.</blockquote><h4><a name = "tag_001_014_1942"> </a>ENVIRONMENT VARIABLES</h4><blockquote>The following environment variables affect the execution of<i>sact</i>:<dl compact><dt><i>LANG</i><dd>Provide a default value for the internationalisation variablesthat are unset or null.If<i>LANG</i>is unset or null, the corresponding value from theimplementation-dependent default locale will be used.If any of the internationalisation variables contains an invalid setting, theutility will behave as if none of the variables had been defined.<dt><i>LC_ALL</i><dd>If set to a non-empty string value,override the values of all the other internationalisation variables.<dt><i>LC_CTYPE</i><dd>Determine thelocale for the interpretation of sequences of bytes of text data ascharacters (for example, single- as opposed to multi-byte charactersin arguments and input files).<dt><i>LC_MESSAGES</i><dd>Determine the locale that should be used to affectthe format and contents of diagnosticmessages written to standard error.<dt><i>NLSPATH</i><dd>Determine the location of message cataloguesfor the processing of<i>LC_MESSAGES .</i></dl></blockquote><h4><a name = "tag_001_014_1943"> </a>ASYNCHRONOUS EVENTS</h4><blockquote>Default.</blockquote><h4><a name = "tag_001_014_1944"> </a>STDOUT</h4><blockquote>The output for each

currently exists in the SCCS file to which changeswill be made to make the new delta.<dt><<i>new SID</i>><dd>Specifies the SID for the new delta to be created.<dt><<i>login</i>><dd>Contains the login name of the user who willmake the delta (that is, who executed a<i><a href="get.html">get</a></i>for editing).<dt><<i>date</i>><dd>Contains the date that<i><a href="get.html">get</a></i><b>-e</b>was

format used by the<i><a href="prs.html">prs</a></i><b>:T:</b>data keyword.</dl><p>If there is more than one named fileor if a directory or standard input is named,each pathname is written before each of the preceding lines:<p><code><tt>"\n%s:\n"</tt>, <<i>pathname</i>></code></blockquote><h4><a name = "tag_001_014_1945"> </a>STDERR</h4><blockquote>Used only for optional informative messages
