Who is a very used command, and, as most of us know, is a command to find out who’s working on your system.). But the who command can do much more then showing who is logged on. On his blog, Mike presents 4 options to use with who that “make it a great troubleshooting and statistics gathering command”. These options are:
who –r : Prints the current runlevel
who –b : Prints the system boot time
who –t : Prints out the last time the System Clock was changed
who –d : Prints out a list of all the dead processes on your system
Linux can do all most anything for you. Here is the proof (found on www.lessaid.net) :
Here is a tip about how to navigate in GNOME-the fast way. While on the desktop (with no window focused), press the / key to open the Nautilus navigation bar.
To navigate to a specific location type the folders path in the bar.
Also, you can navigate to the special locations, using the paths as they are presented on killer tech tips:
Opens the CD Writing Window.
Shows Computer, lists the disk partitions
Lists the available fonts.
Connects you to the specified ftp address.
Lists network locations.
Opens the Samba (file sharing) Window.
Opens the System Settings Window.
Lists the available GNOME themes.
I’m sure that many of you are used with the <Win>+<L> key combination in
windows, to lock the screen. In Ubuntu (the distro I use), the
corespondent shortcut is <CTRL>+<ALT>+<L>. But, in many other distros
there is no shortcut for this command. Here is what you can do to assign a shortcut for locking the screen. (In order to do that, you have to activate the Win key. Read “How to use the Win key in Linux” to find out how to do it.)
Open the gconf-editor by typing “gconf-editor” in the terminal.
Go to: apps>metacity>keybinding_commands
Many users are not aware of the shortcuts that can be use in GNOME and it’s File Manager, Nautilus. Therefore, I made up this list with the most useful (in my opinion) hotkeys. Hope it helps:
Top 15 shortcut keys in Gnome and Nautilus:
Ctrl-N: open new window
Ctrl-Shift-N: create new folder
Ctrl-H: show hidden files
Alt-Home : jump to home folder
Alt-Enter : file / folder properties
F9 : toggle side-pane
Alt-F1 : launch applications menu
Alt-F2 : launch “run application” dialogue
Ctrl-Alt - Right/Left arrow : move to the next virtual desktop
Ctrl-Alt-Shift – Right/Left arrow : take current window to the next virtual desktopCtrl-Alt-D: minimize all windows, and gives focus to the desktop.
Alt-Tab: switch between windows. When you use these shortcut keys, a list of windows that you can select is displayed. Release the keys to select a window.
Ctrl-Alt-Tab: switch the focus between the panels and the desktop. When you use these shortcut keys, a list of items that you can select is displayed. Release the keys to select an item.
Ctrl-Alt-L: lock the screen (it works in Ubuntu-I don’t know about other distros)\
Ctrl-L: shortcut for opening locations-by default the path is the home folder*
A useful hint that I found on the excellent Fosswire blog:
/ : same as Ctrl-L but has the root (/) as default path*
* both shortcuts can be used while you are on the desktop (no window active)
And a suggestion:
Ctrl-T : move to trash (in Nautilus)
This is a dangerous key combination because many of us are used to press these keys in order to open a new tab. Because we all delete items using the Delete key, I recommend to deactivate this shortcut key. To do that, go to System » Preferences » Appearance » Interface. Select Editable menu shortcut keys and close the dialog box. Click on the Edit menu in the File Browser. Click the Empty Trash item (it has Ctrl-T as the keyboard shortcut) Press the Delete key to get rid of the shortcut.

Many new linux users are very confused on how to actually install programs in Linux Distribution. It is true that installing new software in MS Windows is very easy. But in Linux is not only easy but very convenient. Why? In this post you will find the answer.
Let’s say that we need a photo managing software. In Windows we would search on internet after a suitable software and after finding one, we would download the package and install it. Now we will do the same thing in Linux. Let’s say that our linux distro is Ubuntu.
1.Will go to Applications -> Add/Remove and click on it:
3.Under the search box we have the applications which match our filter criteria. There is also a short description of each one of it.
4.Let’s say we would like to try F-Spot Photo Manager. Will check the corresponding box.Click on the “Apply Changes” button.
This is not the only way to install a program in linux. Depending on the linux distribution you have, you could use another package manager (like yum, synaptic, etc.). Or you could use the faster method: the command line. If you know the name of the application you want to install, simply write:
nongeek@mma:~$ sudo apt-get install application_name
or (in fedora):
nongeek@mma:~# yum install application_name
That’s all. Easy, isn’t it?
Let’s list the benefits:
1.We didn’t search all over the internet. We have the most stable applications gathered in one place (called repository).
2.We installed the application with only one click (and a password).
3.We are not afraid of any malware.
I also recommend for reading what is (in my opinion) the best guide about installing applications in linux on the net: How to install ANYTHING in Ubuntu!
