Certain commands to <span class="sc">gdb</span> may produce large amounts of
|
||
|
|
information output to the screen. To help you read all of it,
|
||
|
|
<span class="sc">gdb</span> pauses and asks you for input at the end of each page of
|
||
|
|
output. Type <RET> when you want to see one more page of output,
|
||
|
|
<kbd>q</kbd> to discard the remaining output, or <kbd>c</kbd> to continue
|
||
|
|
without paging for the rest of the current command. Also, the screen
|
||
|
|
width setting determines when to wrap lines of output. Depending on
|
||
|
|
what is being printed, <span class="sc">gdb</span> tries to break the line at a
|
||
|
|
readable place, rather than simply letting it overflow onto the
|
||
|
|
following line.
|
||
|
|
|
||
|
|
<p>Normally <span class="sc">gdb</span> knows the size of the screen from the terminal
|
||
|
|
driver software. For example, on Unix <span class="sc">gdb</span> uses the termcap data base
|
||
|
|
together with the value of the <code>TERM</code> environment variable and the
|
||
|
|
<code>stty rows</code> and <code>stty cols</code> settings. If this is not correct,
|
||
|
|
you can override it with the <code>set height</code> and <code>set
|
||
|
|
width</code> commands:
|
||
|
|
|
||
|
|
|
||
|
|
<a name="index-set-height-1684"></a>
|
||
|
|
<a name="index-set-width-1685"></a>
|
||
|
|
<a name="index-show-width-1686"></a>
|
||
|
|
<a name="index-show-height-1687"></a>
|
||
|
|
<dl><dt><code>set height </code><var>lpp</var><dt><code>set height unlimited</code><dt><code>show height</code><dt><code>set width </code><var>cpl</var><dt><code>set width unlimited</code><dt><code>show width</code><dd>These <code>set</code> commands specify a screen height of <var>lpp</var> lines and
|
||
|
|
a screen width of <var>cpl</var> characters. The associated <code>show</code>
|
||
|
|
commands display the current settings.
|
||
|
|
|
||
|
|
<p>If you specify a height of either <code>unlimited</code> or zero lines,
|
||
|
|
<span class="sc">gdb</span> does not pause during output no matter how long the
|
||
|
|
output is. This is useful if output is to a file or to an editor
|
||
|
|
buffer.
|
||
|
|
|
||
|
|
<p>Likewise, you can specify ‘<samp><span class="samp">set width unlimited</span></samp>’ or ‘<samp><span class="samp">set
|
||
|
|
width 0</span></samp>’ to prevent <span class="sc">gdb</span> from wrapping its output.
|
||
|
|
|
||
|
|
<br><dt><code>set pagination on</code><dt><code>set pagination off</code><dd><a name="index-set-pagination-1688"></a>Turn the output pagination on or off; the default is on. Turning
|
||
|
|
pagination off is the alternative to <code>set height unlimited</code>. Note that
|
||
|
|
running <span class="sc">gdb</span> with the <samp><span class="option">--batch</span></samp> option (see <a href="Mode-Options.html#Mode-Options">-batch</a>) also automatically disables pagination.
|
||
|
|
|
||
|
|
<br><dt><code>show pagination</code><dd><a name="index-show-pagination-1689"></a>Show the current pagination mode.
