It +may be omitted if the word designator begins with a ‘<samp>^</samp>’, ‘<samp>$</samp>’, +‘<samp>*</samp>’, ‘<samp>-</samp>’, or ‘<samp>%</samp>’. Words are numbered from the beginning +of the line, with the first word being denoted by 0 (zero). Words are +inserted into the current line separated by single spaces. +</p> +<p>For example, +</p> +<dl compact="compact"> +<dt><code>!!</code></dt> +<dd><p>designates the preceding command. When you type this, the preceding +command is repeated in toto. +</p> +</dd> +<dt><code>!!:$</code></dt> +<dd><p>designates the last argument of the preceding command. This may be +shortened to <code>!$</code>. +</p> +</dd> +<dt><code>!fi:2</code></dt> +<dd><p>designates the second argument of the most recent command starting with +the letters <code>fi</code>. +</p></dd> +</dl> + +<p>Here are the word designators: +</p> +<dl compact="compact"> +<dt><code>0 (zero)</code></dt> +<dd><p>The <code>0</code>th word. For many applications, this is the command word. +</p> +</dd> +<dt><code><var>n</var></code></dt> +<dd><p>The <var>n</var>th word. +</p> +</dd> +<dt><code>^</code></dt> +<dd><p>The first argument; that is, word 1. +</p> +</dd> +<dt><code>$</code></dt> +<dd><p>The last argument. +</p> +</dd> +<dt><code>%</code></dt> +<dd><p>The first word matched by the most recent ‘<samp>?<var>string</var>?</samp>’ search, +if the search string begins with a character that is part of a word. +</p> +</dd> +<dt><code><var>x</var>-<var>y</var></code></dt> +<dd><p>A range of words; ‘<samp>-<var>y</var></samp>’ abbreviates ‘<samp>0-<var>y</var></samp>’. +</p> +</dd> +<dt><code>*</code></dt> +<dd><p>All of the words, except the <code>0</code>th. This is a synonym for ‘<samp>1-$</samp>’. +It is not an error to use ‘<samp>*</samp>’ if there is just one word in the event; +the empty string is returned in that case. +</p> +</dd> +<dt><code><var>x</var>*</code></dt> +<dd><p>Abbreviates ‘<samp><var>x</var>-$</samp>’ +</p> +</dd> +<dt><code><var>x</var>-</code></dt> +<dd><p>Abbreviates ‘<samp><var>x</var>-$</samp>’ like ‘<samp><var>x</var>*</samp>’, but omits the last word. +If ‘<samp>x</samp>’ is missing, it defaults to 0. +</p> +</dd> +</dl> + +<p>If a word designator is supplied without an event specification, the +previous command is used as the event. +</p> +<hr> +<div class="header"> +<p> +Next: <a href="Modifiers.html#Modifiers" accesskey="n" rel="next">Modifiers</a>, Previous: <a href="Event-Designators.html#Event-Designators" accesskey="p" rel="previous">Event Designators</a>, Up: <a href="History-Interaction.html#History-Interaction" accesskey="u" rel="up">History Interaction</a> [<a href="index.html#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="Concept-Index.html#Concept-Index" title="Index" rel="index">Index</a>]</p> +</div> + + + +</body> +</html> |
