Why is shell scripting required?

• Shell helps in doing work that is repetitive in nature. For example: When executing a bunch of commands, shells can take all these commands directly from a stored file and execute them, instead of writing them every time.
• Used to run routine backups/tasks by admins.
• They are easier to write and debug than other programming languages like PERL, and PYTHON.
• We can transfer the shell script to other UNIX and similar operating systems and execute it.
• Shell scripts are also used to monitor systems regularly.
