[BUG]Improvement in command_utils.py

[Keerthana-T-P]

Describe the bug
*Exception Handling can be added for error clarity like subprocess.CalledProcessError
*Add type annotations for better code clarity and type checking.
*Avoid using shell=True for security reasons, especially with dynamic input. Use a list of arguments instead.

Expected behavior
Error handling and security concerns can be dealt with properly
