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.

upgrading xubuntu to 24.04, fresh install, but I'd like to copy the output of both dpkg -l and history to a usb stick.

About history: will it copy all commands I executed on all tabs? I work with several tabs simultaneously.

ETA: thank you for all your input, problem has been solved.

I'm pretty sure the history command outputs only commands from the shell/tab it's invoked in plus the commands already saved to the shells history file. Commands are not always saved to the file immediately. So to make 100% sure, you have to clean exit all shells before using history.

You can easily test this by using a unique command (like: echo 123) in one shell and history in another.

Also the shell probably has a man page detailing config options that affect the history.
