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.

wish I knew how to use the journal, seems like there isn't any good way to just search the previous session's logs without a mountain of fuss or having to guess file names
Check that you actually have persistent storage enabled. (See
man journald.confand search forStorage)Read up on the numerous parameters to journalctl. (
man journalctl)journalctl --boot -2will show logs from previous boot.journalctl --since "-2 weeks" --unit=sshdlast two weeks worth of sshd logs.I think there's a minor mistake in your command.
jounalctl --boot -1is the previous boot. The counting starts at--boot 0for the current one.You're right ofcourse.
