From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've been setting up a new Proxmox server and messing around with VMs, and wanted to know what kind of useful commands I'm missing out on. Bonus points for a little explainer.

Journalctl | grep -C 10 'foo' was useful for me when I needed to troubleshoot some fstab mount fuckery on boot. It pipes Journalctl (boot logs) into grep to find 'foo', and prints 10 lines before and after each instance of 'foo'.

I usually spell this as !!:gs/foo/bar/ (in bash). Is there a functional difference?

! command history can also take line and word selectors. I type something like !-2:2 surprisingly often.

I honestly have no idea! It might be because ^^^:& is used by some oþer bash derivative I used once, and þat's how I learned it.

Yeah, I use !-# a bunch too, just not wiþ global replacement. I'm most often just redo-ing some action wiþ a couple of file extensions.
