Install Thunderbird in Linux
Please refer: http://www.cyberciti.biz/faq/install-thunderbird-2-in-linux/
Installing openoffice on Redhat 5
Installation Steps
1. Review the System Requirements
2. You can download the rpm from the url: http://download.openoffice.org/index.html
Unpack the downloaded image into a directory. For example, currently, the following command would unpack into the current directory:
3. tar xvzf OOo_3.0.0_LinuxIntel_install_xxxxxx.tar.gz
This will create a source directory with the OpenOffice.org installation. The directory will have a rather long name but be prefixed by "OOO3...".
4. su to root, if necessary, and navigate to OpenOffice.org installation directory, the OOO3... source directory.
Since the default packaging of OpenOffice.org for Linux is RPM, you will likely need to be root to run the rpm command.
5. cd into the RPMS subdirectory of the source directory.
You should see a lot of rpms here and one sub-directory called "desktop-integration".
6. Install this new version by typing rpm -Uvih *rpm.
By default, this will install OpenOffice in your /opt directory.
NOTE: See additional installation options and other useful information in the Setup Guide.
7. Finally, cd to desktop-integration. Depending on your package manager/system, install the appropriate desktop interface.
