Why Shell Scripting is Important in DevOps?

The main use of shell scripting, a programming language created specifically for the Linux kernel, is to automate repetitive processes carried out on operating systems.

For Example:

• Monitoring system resources

• Automating Code Compilation and Commands

• Managing user accounts and files

Because it is widely available on all Linux command lines and used on Linux Terminal, the Shell is quite well-liked. As shell communicates with the operating system via the command line interface, this helps to lower the hardware's graphics resources.
