What tools are commonly used for Linux?

Linux is valuable for MCA students because many servers, development environments and cloud systems use Linux. Basic shell commands, permissions, processes and package management are useful starting points. Students can judge their progress in Linux by solving problems independently instead of depending entirely on guided tutorials. This point is specifically relevant to the Linux aspect of MCA study. For this specific question about Linux, the practical takeaway is to relate the concept to your own MCA learning goal.
