This post introduces how to use widgets in WordPress.
Widgets are tiny blocks of specific functionality that you can place in your WordPress sidebars (also known as widget-ready-areas). This is an easy way to add things like galleries, quotes, popular posts, and other dynamic items such as maps on their WordPress site.
Widgets can be found on Appearance » Widgets page in your WordPress admin area.
You will see the widgets that you can add under the list of available widgets.
On your right hand, you will find the designated areas on your WordPress site where you can place these widgets. These designated areas are defined by your WordPress theme. They are called sidebars or widget-ready areas.
If you don’t see a specific widget you’re looking for, then it can likely be added with a plugin (more on this later).
There are multiple ways to add widgets to sidebars available in your WordPress theme.
(1) The easiest one is to simply drag and drop them to your sidebar.
(2) You can also click on a widget title from the list of available widget. WordPress will show you the list of sidebars where you can add this widget.
Simply select the sidebar where you want to add the widget, and then click on Add widget button to add it.
Removing a widget in WordPress is just as simple as adding them. Visit the Appearance » Widgets page.
Look for the widget that you want to remove in your sidebars and click on the widget title to expand it.
Below the widget settings, you will find the link to delete the widget. Deleting a widget will remove it from your sidebar and will also delete widget settings like title or any options that you selected.
Some widgets are too simple and don’t have many options in their settings while others have many options and settings. If you would like to remove a widget without losing the settings, then you need to drag and drop it to the inactive widgets section.
Deleting or sending a widget to inactive widgets does not remove it from the list of available widgets. You can always add a widget again from the list of available widgets or inactive widgets.
A default WordPress installation comes with some built-in widgets like recent posts, recent comments, archives, search, etc.
Many WordPress themes and plugins come with their own plugins.
For example, Envira Gallery plugin allows you to create beautiful image galleries in your WordPress posts and pages. But it also comes with an Envira Gallery widget, which you can add to a sidebar to display image galleries in WordPress.
Similarly, countless other themes and plugins add widgets, so their users can add things to their WordPress sidebars without writing any code or html.
There are hundreds of WordPress plugins that just add widgets for you to use in your sidebar. See our list of the 25 most useful WordPress widgets for your site.
To check hard disk usage on Ubuntu from a terminal (command line), issue the following command in your terminal.
liping:~$ df -h
-h stands for human which makes it readable by us humans, otherwise the file size will be in bytes:)
After you issue the command, you would see your disk usage similar to the info given below.
Filesystem Size Used Avail Use% Mounted on /dev/sda7 68G 23G 43G 35% / udev 10M 0 10M 0% /dev tmpfs 800M 1.6M 798M 1% /run tmpfs 5.0M 0 5.0M 0% /run/lock /dev/sda6 264G 173G 78G 69% /home tmpfs 3.2G 992K 3.2G 1% /tmp . . .
