Firefox has built-in keyboard shortcuts for quickly navigating directly to the tab you want to get to. This is very useful when you are using Google Reader or Bloglines to read RSS feeds, and you’ve opened up a bunch of tabs. Before discovering this trick, I always used Ctrl+Tab to navigate back, or had to use the mouse.
If you have installed multiple versions of an application into your system, you may wonder which command is being run from the command line when you launch it. This is especially useful to figure out the path of php when running on a shared server, as many shared servers have both php4 and php5 installed.
Solaris includes a command line utility to get basic current system configuration information and output it to the console.
It’s easy to get the type of processor that a Solaris box is running on. While this might seem like a silly thing to need to know, if you are connected into a Solaris server at a remote location, you may need to know what type of processor is being used in order to install the correct packages.
With the release of Windows Vista around the corner, I started wondering if my laptop will even run Vista. Thankfully Microsoft provides a utility to examine your system and let you know if you need to upgrade anything.
Installing software on Ubuntu usually entails using Synaptic or by using an apt-get command from the terminal. Unfortunately, there are still a number of packages out there that are only distributed in RPM format.
Ubuntu Linux has a rich set of commands for manipulating and accessing files. The du utility gives information on disk usage, and the sort utility can sort the results. Finally, we can run those results through the head command, which gives you the top 10 lines outputted through any other command. We’ll chain the commands together to get the output that we want.
A frequent task when designing applications that work with TCP/IP and the internet is to lookup an IP address from a hostname. It’s much easier for users to deal with the hostname than having to type in an IP address.
KDE has an extremely powerful scripted user interface through the use of the dcop utility. You can control virtually any KDE application by entering dcop commands through shell scripts or from the shell itself. These actions can then be tied to menu items, and even hot keys. KDE can also be installed on Ubuntu through the kubuntu-desktop package.
If you mess around in the registry, or install some different software packages that add things to the right-click menu, you can end up with a problem where the default action on a folder is always “Search…”, even though you set it to something else.
A hidden functionality in Windows allows you to right click on a directory, and select “Command Prompt Here” from the menu.
Kubuntu Linux runs the the desktop as a regular user account, and so all programs launched are launched in the context of a normal user account.
