A short command on how to change Ubuntu so that it will only start in text mode, no X11 (graphical) mode. The following removes the graphical greeter from the runlevels :
sudo update-rc.d -f gdm remove
Write a disk full with files with random or zero data
I wanted to test a hard-drive that halted when its internal temperature raised above its safety level. hdparm is one option but the script below creates different files with a certain given size.
#!/bin/bash
COUNTER=0
while [ true ]; do
dd if=/dev/zero of=file$COUNTER bs=$1 count=1024
let COUNTER=COUNTER+1
done
COUNTER=0
while [ true ]; do
dd if=/dev/zero of=file$COUNTER bs=$1 count=1024
let COUNTER=COUNTER+1
done
You can replace /dev/zero with /dev/random if you want random data. Call the script with one argument, the file size.
Set the default height and width of a gnome-terminal
Launch it with gnome-terminal –geometry 135×30 (edit the menu or create a new launcher).
Adjust the launchsettings in ~/.xbindkeysrc
“gnome-terminal –geometry 135×30”
m:0x10 + c:116
m:0x10 + c:116
Show comment box / comments on a WordPress Page
Just include this in your theme / template for the WP-pages :
<?php comments_template(); ?>
If you’re not happy with the default then just edit the file comment.php
WordPress, printing ParentChild menus
Worpress allows you to print parent menu’s with different child-menus. Implementation is easy, just add this to your themes.
In the file that creates the header of your page, normally header.php, add this code:
<?php $args = array(
'title_li' => '',
'sort_column'=>'menu_order',
'depth' => 1
);
wp_list_pages($args);
?>
Then in the file that creates your child menu (normally this should be sidebar.php) add this code:
<?php
if($post->post_parent) {
$children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
}
else {
$children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
}
if ($children) { ?>
<ul>
<?php echo $children; ?>
</ul>
<?php } ?>
The selected menus are li.current_page_parent and li.current_page_item so you should adjust their style in your stylesheet.
