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'.

For interactive editing, the keybind alt+. inserts the last argument from the previous command. Using this instead of $_ has the potential to make your shell history a little more explicit. (vim $_ isn't as likely to work a few commands later, but vim actual_file.sh might)

You can also press alt+. multiple times to cycle through all recent arguments

Yes, definitely and I do run into that when I search my history
