There is no limit on +how long it can be. It starts with a command name, which is followed by +arguments whose meaning depends on the command name. For example, the +command <code>step</code> accepts an argument which is the number of times to +step, as in ‘<samp>step 5</samp>’. You can also use the <code>step</code> command +with no arguments. Some commands do not allow any arguments. +</p> +<a name="index-abbreviation"></a> +<p><small>GDB</small> command names may always be truncated if that abbreviation is +unambiguous. Other possible command abbreviations are listed in the +documentation for individual commands. In some cases, even ambiguous +abbreviations are allowed; for example, <code>s</code> is specially defined as +equivalent to <code>step</code> even though there are other commands whose +names start with <code>s</code>. You can test abbreviations by using them as +arguments to the <code>help</code> command. +</p> +<a name="index-repeating-commands"></a> +<a name="index-RET-_0028repeat-last-command_0029"></a> +<p>A blank line as input to <small>GDB</small> (typing just <tt class="key">RET</tt>) means to +repeat the previous command. Certain commands (for example, <code>run</code>) +will not repeat this way; these are commands whose unintentional +repetition might cause trouble and which you are unlikely to want to +repeat. User-defined commands can disable this feature; see +<a href="Define.html#Define">dont-repeat</a>. +</p> +<p>The <code>list</code> and <code>x</code> commands, when you repeat them with +<tt class="key">RET</tt>, construct new arguments rather than repeating +exactly as typed. This permits easy scanning of source or memory. +</p> +<p><small>GDB</small> can also use <tt class="key">RET</tt> in another way: to partition lengthy +output, in a way similar to the common utility <code>more</code> +(see <a href="Screen-Size.html#Screen-Size">Screen Size</a>). Since it is easy to press one +<tt class="key">RET</tt> too many in this situation, <small>GDB</small> disables command +repetition after any command that generates this sort of display. +</p> +<a name="index-_0023-_0028a-comment_0029"></a> +<a name="index-comment"></a> +<p>Any text from a <kbd>#</kbd> to the end of the line is a comment; it does +nothing. This is useful mainly in command files (see <a href="Command-Files.html#Command-Files">Command Files</a>). +</p> +<a name="index-repeating-command-sequences"></a> +<a name="index-Ctrl_002do-_0028operate_002dand_002dget_002dnext_0029"></a> +<p>The <kbd>Ctrl-o</kbd> binding is useful for repeating a complex sequence of +commands. This command accepts the current line, like <tt class="key">RET</tt>, and +then fetches the next line relative to the current line from the history +for editing. +</p> + +<hr> +<div class="header"> +<p> +Next: <a href="Command-Settings.html#Command-Settings" accesskey="n" rel="next">Command Settings</a>, Up: <a href="Commands.html#Commands" accesskey="u" rel="up">Commands</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> |
