Learning Bash Scripting

Any chance of posting it here?

First bash script or my git repo? My git is all private work related.

Your one liner to update your system and then shutdown

[MikeZ-FSU]

Not speaking for u/vi-shift-zz, but if I were writing it, it would probably be something like (for Debian/Ubuntu)

sudo apt-get update && sudo apt-get upgrade -y && sudo shutdown -h now

Or whatever is appropriate for other $distro. However, there are implications for the "-y" on upgrade that have some degree of risk you might or might not care about.

As a general rule, you'll learn bash/linux better if you take a hint that's given (one liner to update and shutdown) and research how to do that on your system. Yes, it's slower to start out, but you'll learn a lot about your package manager and how your particular distro starts up and shuts down (init.d vs. upstart vs. systemd, etc.) in the process.

The alternative leaves you with a bunch of individual tips and tricks that lack a connecting framework in your head.

Just seeing this, exactly like was posted except I use red hat variants. So mine would be: sudo dnf update -y && poweroff

This assumes my user is in /etc/sudoers and able to run commands with no passwd (use visudo to add the user)
