Introduction to the Bash Shell
The Linux command line is provided by a program called the shell. Over the years, the shell program has evolved to cater to various options.
Different users can be configured to use different shells. But most users prefer to stick with the current default shell. The default shell for many Linux distros is the GNU Bourne-Again Shell (bash). Bash is succeeded by Bourne shell (sh).
