<P><B>uustat</B> <I>option(s)</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>uustat</B> command returns information about the UUCP status. See the online-manual pages for a list of the available options.</P>
<P><FONT SIZE="+1"><B>uux......<TT>Remote Execution</TT></B></FONT></P>
<P><B>uux</B> <I>option(s) command</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>uux</B> command executes a command on a remote system, or executes a command on the local system using files from remote systems. See the online-manual pages for a list of the available options.</P>
<P><FONT SIZE="+1"><B>vrfy......<TT>Verify E-Mail Address</TT></B></FONT></P>
<P><B>vrfy</B> <I>option(s) address hostname</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>vrfy</B> command verifies the existence and accuracy of an e-mail address. If the host is known, that information can be added to the command line, increasing the chances that the existence and accuracy can be verified. If the hostname is not specified, the information may have to go through other mail systems, which can decrease the accuracy.</P>
<P>See the online-manual pages for a list of the available options.</P>

<P><B>wnewmail</B> <I>filename</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>wnewmail</B> daemon checks every 10 seconds to see if there is any new mail. It’s similar to <B>biff</B> and <B>xbiff</B>, except with less flexibility.</P>

<P><B>PROGRAMMING COMMANDS</B></P>
<P>These are some of the basic programming commands that ship with most Linux implementations. The Linux operating system is actually a programmer’s dream environment; these commands will get you going, but there are additional programming tools covered in the online-manual pages.
</P>
<P><FONT SIZE="+1"><B>ansi2knr......<TT>Converts ANSI C to K&R C</TT></B></FONT></P>
<P><B>ansi2knr</B> <I>input_file output_file</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>This command converts a standard ANSI C file to a file that meets Kernighan & Ritchie C specifications. Be warned that there are no error messages, so if the translation failed, you won’t know.
</P>
<P><FONT SIZE="+1"><B><I>EXAMPLE</I></B></FONT></P>
<!-- CODE SNIP //-->
<PRE>
$ ansi2knr oldfile.c newfile.c
</PRE>
<!-- END CODE SNIP //-->
<P><FONT SIZE="+1"><B>ar......<TT>Manipulate Archives</TT></B></FONT></P>
<IMG SRC="images/05-135i.jpg"><P><B>ar</B> <I>arguments membername file(s)</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>ar</B> command is used to create, modify, and extract from archive files. Archive files are a collection of files stored in a single file, which makes them easier to store and manage in filesystem and device usage. All the important elements of files, including permissions, owners, timestamp, and group, are saved in the archive.</P>
<P>This command is used most in programming situations, as it is used to create libraries that contain frequently used subroutines.</P>
<P>A <I>membername</I> is a file that already exists within the archive. Some of the options, particularly those that specify the order of files within the archive, rely on a <I>membername</I>.</P>
<P>Two arguments to the <B>ar</B> command are required: an option of some sort that specifies the operation, and the name of the file. This command can be confusing, since the option usually must begin with <B>p</B>.</P><P><BR></P>
