<h4 class="subsection">32.2.4 Readline Arguments</h4>
|
||
|
|
|
||
|
|
<p>You can pass numeric arguments to Readline commands. Sometimes the
|
||
|
|
argument acts as a repeat count, other times it is the <i>sign</i> of the
|
||
|
|
argument that is significant. If you pass a negative argument to a
|
||
|
|
command which normally acts in a forward direction, that command will
|
||
|
|
act in a backward direction. For example, to kill text back to the
|
||
|
|
start of the line, you might type ‘<samp><span class="samp">M-- C-k</span></samp>’.
|
||
|
|
|
||
|
|
<p>The general way to pass numeric arguments to a command is to type meta
|
||
|
|
digits before the command. If the first `digit' typed is a minus
|
||
|
|
sign (‘<samp><span class="samp">-</span></samp>’), then the sign of the argument will be negative. Once
|
||
|
|
you have typed one meta digit to get the argument started, you can type
|
||
|
|
the remainder of the digits, and then the command. For example, to give
|
||
|
|
the <kbd>C-d</kbd> command an argument of 10, you could type ‘<samp><span class="samp">M-1 0 C-d</span></samp>’,
|
||
|
|
which will delete the next ten characters on the input line.
