Oftentimes the -output of a particular command is too big to fit on one screen. The individual commands -do not know how to fit their output to separate screens. They leave this job to the pager -utility.</p> - -<p>The <tt class="COMMAND">more</tt> command breaks the output into individual screens -and waits for you to press the space bar before continuing on to the next screen. -Pressing the enter key will advance the output one line. Here is a good example:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">cd /usr/bin</kbd> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">ls -l</kbd> -</pre> -</td> -</tr> -</table> - -<p>That should scroll for a while. To break up the output screen by screen, just pipe it -through more:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">ls -l | more</kbd> -</pre> -</td> -</tr> -</table> - -<p>That is the pipe character (shift backslash). The pipe is short for saying take the -output of <tt class="COMMAND">ls</tt> and feed it into <tt class="COMMAND">more</tt>. You -can pipe just about anything through the <tt class="COMMAND">more</tt> command, not just -<tt class="COMMAND">ls</tt>. Piping is also covered in <a -href="shell-command-line.html#SHELL-COMMAND-LINE-PIPING">Section 8.2.3</a>.</p> -</div> - -<div class="SECT2"> -<h2 class="SECT2"><a id="AEN3518" name="AEN3518">10.2.2 <tt -class="COMMAND">less</tt></a></h2> - -<p>The <tt class="COMMAND">more</tt> command is quite handy, but often you will find that -you have advanced past the screen you wanted. more does not provide a way to go back. The -<tt class="COMMAND">less</tt>(1) command provides this functionality. It is used in the -same way as the <tt class="COMMAND">more</tt> command, so the previous examples apply -here too. So, <tt class="COMMAND">less</tt> is more than <tt class="COMMAND">more</tt>. -Joost Kremers puts it this way:</p> - -<a id="AEN3530" name="AEN3530"></a> -<blockquote class="BLOCKQUOTE"> -<p><tt class="COMMAND">less</tt> is more, but more <tt class="COMMAND">more</tt> than <tt -class="COMMAND">more</tt> is, so <tt class="COMMAND">more</tt> is less <tt -class="COMMAND">less</tt>, so use more <tt class="COMMAND">less</tt> if you want less <tt -class="COMMAND">more</tt>.</p> -</blockquote> -</div> - -<div class="SECT2"> -<h2 class="SECT2"><a id="AEN3539" name="AEN3539">10.2.3 <tt -class="COMMAND">most</tt></a></h2> - -<p>Where <tt class="COMMAND">more</tt> and <tt class="COMMAND">less</tt> leave off, <tt -class="COMMAND">most</tt>(1) picks back up. If <tt class="COMMAND">less</tt> is more than -<tt class="COMMAND">more</tt>, <tt class="COMMAND">most</tt> is more than <tt -class="COMMAND">less</tt>. Whereas the other pagers can only display one file at a time, -<tt class="COMMAND">most</tt> is capable of viewing any number of files, as long as each -file's window is at least 2 lines long. <tt class="COMMAND">most</tt> has a lot of -options, check the man page for full details.</p> -</div> -</div> - -<div class="NAVFOOTER"> -<hr align="LEFT" width="100%" /> -<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" -cellspacing="0"> -<tr> -<td width="33%" align="left" valign="top"><a href="file-commands.html" -accesskey="P">Prev</a></td> -<td width="34%" align="center" valign="top"><a href="index.html" -accesskey="H">Home</a></td> -<td width="33%" align="right" valign="top"><a href="file-commands-output.html" -accesskey="N">Next</a></td> -</tr> - -<tr> -<td width="33%" align="left" valign="top">Handling Files and Directories</td> -<td width="34%" align="center" valign="top"><a href="file-commands.html" -accesskey="U">Up</a></td> -<td width="33%" align="right" valign="top">Simple Output: <tt class="COMMAND">cat</tt> -and <tt class="COMMAND">echo</tt></td> -</tr> -</table> -</div> -</body> -</html> - |
