Why is Linux important to Data Engineers

Linux is a kernel distribution used by programmers. It's an easier way for programmers to use it, as there are different Linux distributions. There is Ubuntu (Ubuntu.com), Parrot (parrotsec.org), used for security, and Kali (Kali Linux). Different programmers and developers use different distributions.
Although different, they all have similar commands, and one can use them easily.

Why is Linux important to Data Engineers

• Its important for a Data engineer as it makes their work easier when working through Docker, easy to navigate through, as we work with SQL, just to name a few. It's open source and cost-effective, which means it's free, and most of its products are free to use compared to other operating systems. *Its performance is high, efficient and easy to use in big data and handling massive data as well. *Its more flexible and automated with scripting capabilities, e.g., Bash coz the DE can integrate data with ETL tools.

• cd- Changes directory
• cd .. - returns to the previous page
• touch - Creates an empty file
• mv - Moves or renames files
• rm - Deletes files

Conclusion
Its easy for a newbie to get through Data Engineering, passion and dedication are all that is required to help the learner get through having an open mind and willingness to work through.
