Handling (Tar/GZip) and (Tar/Bzip2) archives

(Tar/GZip) archives end in ".tar.gz" and (Tar/Bzip2) archives end in ".tar.bz2". Bzip2 is the newer, more efficient compression method. These files can generally be automatically extracted by merely clicking on them from your file manager (Nautilus), since file associations with the appropriate archival utilities are set by default in Ubuntu. These instructions are for those who wish to use the command line Terminal.

To extract:

tar xvf packagename.tar.gz

Note: tar is an application which can extract files from an archive, decompressing if necessary.

-x means extract.

-v means verbose (list what it is extracting).

-f specifies the file to use.

Decompressing ".gz" files

gunzip file.gz

Decompressing ".bz2" files

bunzip2 file.bz2

Note: You can also decompress a package first by using the command gunzip (for .gz) or bunzip2 (for .bz2), leaving the .tar file. You would then use tar to extract it.

To create a .gz archive:

tar cvfz packagename.tar.gz folder

To create a .bz2 archive:

tar cvfj packagename.tar.bz2 folder

wbar: a quick luanch bar( similar to avant and cairo dock)

wbar is a quick-launch bar (not a dock) that has an appearance similar to Avant Window Manager and Cairo Dock. It is GTK (Gnome) based but can work in all desktop environments. It does not require a compositing manager to be installed and is therefore quicker and more suitable for low-end hardware systems. It is the default in the Google gOS desktop and is available as a .deb package from Google. Download and install (from the command-line Terminal): wget http://wbar.googlecode.com/files/wbar_1.3.3_i386.deb sudo dpkg -i wbar_1.3.3_i386.deb Start wbar with custom start options (e.g. by pressing alt+F2). Here is an example: wbar -isize 48 -j 1 -p bottom -balfa 40 -bpress -nanim 3 -z 2.5 -above-desk Here is another example: wbar -above-desk -pos bottom -isize 60 -nanim 1 -bpress -jumpf 0.0 -zoomf 1.5 For a full list of command-line startup options, see: wbar --help Tip: If you want the "wave" effect just increase the -nanim value. I like the icons to just pop up so I do...
