CLI Companion 1.0 RC2

Leave a comment

.
CLI Companion is an Terminal with an attached ‘command dictionary’. The application comes with a set of commands already added to the dictionary. However CLI Companion lets you add as many commands as you want to the ‘command dictionary’.And it’s a GUI that displays a list of commands and an embedded terminal under it. The application comes with a list of commonly used commands by default, each having a short description and if you want to find out more about a certain command, simply right click it and select “Help”. This will display the “man” (manual) for the selected command. But CLI Companion can help advanced users too as you can use it to store long commands which you can then easily find using the search feature.


CLI Companion 1.0 RC2 (29/11/2010) brings 2 features designed to make CLI Companion more useful as a daily terminal:
  • the command list can now be collapsed and expand as needed (see screenshot below)
  • The format commands are stored in has been changed. Commands requiring User Input when ran now use question marks(?) as place holders. So a command like ‘ls /any/directory’ would be added to your command list as ‘ls ?’. This changed was required because the old behavior only allowed user input at the end of the command.

To install the latest CLI Companion 1.0 RC2 in Ubuntu , use the following commands:

sudo add-apt-repository ppa:clicompanion-devs/clicompanion-nightlies
sudo apt-get update
sudo apt-get install clicompanion

You’ll then find CLI Companion under Applications > Accessories.

RadioTray 0.6.3 Released With Ubuntu AppIndicator Support

Leave a comment

RadioTray is a minimalistic radio player stat runs in the notification area (system tray).
Finally a new version of RadioTray was released which adds support for Ubuntu appindicator, a new command line parameter “–resume” to play the last radio station before RadioTray was shutdown and a new sleep timer so you can go to sleep while listening using RadioTray. These features were actually included in the 0.6.2 version which was released yesterday but a bug prevented it from running so version 0.6.3 was released to fix that.

Install RadioTray 0.6.3 in Ubuntu

1. Download RadioTray Ubuntu .deb from Sourceforge and install it normally. If you encounter any issues, read on. If not, enjoy RadioTray!

Possible issues:

a) If you use the Faenza Icon theme installed from a PPA, the RadioTray installation will return an error and it will fail to install. Fix it using the following command:

sudo dpkg -i --force-all /var/cache/apt/archives/radiotray_0.6.3_all.deb 
#or replace with the path to where you've downloaded radiotray
.
b) If you’ve installed 0.6.2 and it failed to start for you, to be able to use 0.6.3 you’ll have to run the following command (warning: it will remove all the configuration files):
.
rm -r /.local/share/radiotray
And that’s it, enjoy!

How To Install JDownloader in Ubuntu

Leave a comment

What is JDownloader ?

JDownloader is open source, platform independent and written completely in Java. It simplifies downloading files from One-Click-Hosters like Rapidshare.com or Megaupload.com – not only for users with a premium account but also for users who don’t pay. It offers downloading in multiple paralell streams, captcha recognition, automatical file extraction and much more. Of course, JDownloader is absolutely free of charge. Additionally, many “link encryption” sites are supported – so you just paste the “encrypted” links and JD does the rest. JDownloader can import CCF, RSDF and the new DLC files.

Install JDownloader in Ubuntu

Add the ppa and install JDownloader using the following commands:

sudo add-apt-repository ppa:jd-team/jdownloader

sudo apt-get update && sudo apt-get install jdownloader

Install VirtualBox 4.0 (Stable) In Ubuntu, Via Repository

Leave a comment

As you probably know, starting with VirtualBox 4.0 some features are now available separately, in an extension pack. Here are the step-by-step instructions on installing both VirtualBox and the Extensions Pack in Ubuntu.

Install VirtualBox 4.0 in Ubuntu

 

1. Remove any previous VirtualBox version you had installed.
Presuming you were using version 3.2, you would have to run the following command:
.
sudo apt-get remove virtualbox-3.2

 

2. Add the VirtualBox contrib repository and install VirtualBox 4.0:

VirtualBox 4.0 is no longer available in the non-free component of the VirtualBox Ubuntu repository but in contrib.
Add it and install VirtualBox using the following commands:

 

sudo -v
echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -sc) contrib" | sudo tee -a /etc/apt/sources.list
wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -
sudo apt-get update
sudo apt-get install virtualbox-4.0

 

3. Download the Extension Pack.
For USB 2.0 devices, VirtualBox RDP and PXE boot for Intel cards support, you’ll also have to install an Extension pack which you can download from HERE.

4. Install the VirtualBox Extension pack.


Open VirtualBox 4.0 and go to File > Preferences and on the Extensions tab, click the “add” button on the right (first blue diamond) and browse for the VirtualBox extension pack you’ve downloaded in step 1. That’s it!

How To “Really” Hide Folders In Ubuntu Using The Gobolinux Kernel And Gobohide

Leave a comment

What Gobohide does is completely hide some folder you chose at kernel level:

[… ] My suggestion was to hook these read operations directly in the root of the problem: since every readdir() is performed by the kernel, then we could have a list kept in kernel to check on every readdir() operation. If the inode being read was present in this list, then it simply shouldn’t be copied onto the destination buffer, which should be returned to the user.

This first implementation was hardcoded with my own inode numbers (relative to the legacy tree), and this was when Felipe Damasio came with his kernel abilities and created a better interface based on ioctls in order to register the entries that should be hidden from the userspace, and then we got our first release of GoboHide.

From these old days until now, GoboHide has been kept up to date to the newer kernel versions. The patch now is fully integrated with the VFS, which means that it works with any filesystem that supports directories and/or symlinks. It has been tested with EXT2, EXT3, ISOfs, JFFS2, JFS, NFS, ReiserFS, SquashFS and XFS, but certainly works with others, too.

— info via Gobolinux

Once a folder is hidden, it doesn’t show up in the file manager (if the folders were already displayed, refresh Nautilus – CTRL + R), terminal or any other place anymore. However, the folders are still accessible as long as you know their exact path – you can type it in a file manager or terminal and access the files inside them without having to unhide them.
In my test, typing the exact path to a hidden folder never worked the first time but always worked the second time. This might be a bug or just some weird issue on my system, anyway in case this happens to you too, just try it again and it should work.

Usage

 

Firstly make sure you install all 3 .deb files (download link at the end of the post) and restart your computer. Then, to hide a folder use the following command:


sudo gobohide -h /path/to/folder/to/hide

 

To unhide a folder use:

sudo gobohide -u /path/to/folder/to/unhide

 

To list the currently hidden folders use:

sudo gobohide -l

 

You can also see all these commands in the screenshot in the beginning of the post.

Since I’m not the one who has created these .deb files I cannot give you any guarantees so use them at your own risk! Also, use them in Ubuntu 10.10 Maverick Meerkat only (I have not tested them with older Ubuntu versions)!

 

Download Gobolinux Kernel and Gobohide (install all 3 packages)

How To Speed Up Boot Process in Ubuntu

2 Comments

When your Ubuntu system boots, you will see the GRUB menu if you hit the Esc key, or if you’ve enabled the menu to show by default. The only issue with this is that the default timeout is only 3 seconds. You may want to increase this amount… or you may even want to decrease it. Either one is simple.
Open up the /boot/grub/menu.lst file in your favorite text editor.

gksudo gedit /boot/grub/menu.lst

Now find the section that looks like this:

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 3

The timeout value is in seconds. Save the file, and when you reboot you will have that many seconds to choose the menu item you want.
