Python, R, and SQL are often cited as the most-used languages for processing, modeling, and exploring data. While that may be true, there is no reason that others can't be -- or are not being -- used to do this work. The Bash shell is a Unix and Unix-like operating system shell, along with the commands and programming language that go along with it. Bash scripts are programs written using this Bash shell scripting language. These scripts are executed sequentially by the Bash interpreter, and can include all of the constructs typically found in other programming languages, including conditional statements, loops, and variables. Bash scripting is also used to orchestrate the deployment and management of complex distributed systems, making it an incredibly useful skill in the arenas of data engineering, cloud computing environments, and DevOps.
