How to change the system timezone in Linux

In Linux, the system time zone is determined by the symbolic link /etc/localtime. This symbolic link points to a time zone data file located at either /usr/share/zoneinfo or /usr/lib/zoneinfo depending on Linux distribution. So changing the system timezone is just a simple job of updating this symbolic link. Run the following command to view the list of regions

ls -l /usr/share/zoneinfo

How to include a file in a bash shell script

I had written few shell scripts for a project. All these scripts were using some common configuration parameters so I decided to put them in a common file and include it in the scripts file so that when I move the script files from the development to the production environment, I have to change the values in only one file. My configuration file "config.conf" contained variables like:

DB_HOST=127.0.0.1
DB_PORT=3306
DB_USER=testuser
DB_PASS=test123

To install .deb files from shell/command prompt you can use the dpkg command. dpkg is a package manager for Debian based systems. It can install, remove, and build packages, but unlike other package management system's it can not automatically download and install packages and their dependencies.
