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.

yeah that looks exactly like what i wanted, thanks! i probably should have asked my question a couple years ago but i was still very new to linux and didn't quite know the lingo. i'm still not quite sure how < works in general but i get the pipe and other redirects at least.

putting it in .bash_logout doesn't always work. something involving login shells i don't quite understand yet but i'll read more about it. i saw mention of putting exit_session() { . "$HOME/.bash_logout" } trap exit_session SIGHUP in .bashrc to make it always work but i also don't understand trap yet either so i'll look into that too.

thanks again, your reply helped point me in the right direction of things i want to learn!

when calling cat <(echo data from the stdin stream) from_file.txt, you get the data in the first argument from a stream. With the .bash_logout I do not have much experience yet.
