Bourne-Again Shell (Bash)

Bash is an acronym for "Bourne-Again Shell", the name of a code interpreter and a high-level programming language, and it is a must-know tool in Computational Chemistry and Biology. You can use Bash scripting in Unix/Linux computers through a terminal. When you initialize the shell, i.e, the interpreter, your computer runs initialization files -- ~/.bash_profile, ~/.bash_login, and ~/.profile (where ~/ points to your home directory) -- but we do not recommend changing these files unless you really know what you are doing. In most cases, you can change the ~/.bashrc file, which allows the user to customize the system according to their needs.
