Bash or Shell script is a computer program designed to be run by the Unix shell, a command-line interpreter. There are various dialects of shell scripts and are considered to be scripting languages. Commonly known dialects are Korn shell (ksh), Bash shell (bash/sh), C shell (csh). All the major dialects are supported in any of the Unix based Operating Systems. Hence, if you are good at programming in one of the dialects, you are covered.
Shell scripting is the term that is also used more generally to mean the automated mode of running set of programs in an operating system shell. It is another fundamental skill that every Data Engineer should poses as most of the servers are Unix based and need to access them through command line all the time. There are a lot of ways you can develop automated pipelines just through proper shell scripting skills. Deploy and schedule them through the crontab utility.
Shell scripting is important for product deployment and management, CI/CD, Data Pipelines, Engineering, Web servers, Hosting, Automations, Database Management and many more. Hence it is obligatory to learn this scripting language.
