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.

Kitty is great until you SSH into a machine where it's not installed and try to use tmux or some other commandline apps
@flashgnash @Laser Connecting once with its ssh kitten resolves this by uploading appropriate terminfo files to the user's directory.
I didn't realise it was only once you had to use it
@flashgnash Yep, just once to transfer the terminfo files and resolve this.
The SSH kitten is pretty useful though. If you use it in combination with kitty's --single-instance mode, you can start new kitty windows in the same SSH session without logging in again using its shared connection feature. Hugely convenient for how I work at least.
I have used it for that feature before, is there not a concern around defense in depth there though? If you've got a rogue program running could it not then hijack your ssh connection and infect that machine as well?
If it's a machine you have control over you can install the terminfo. Or setting the TERM variable to something like xterm-256color when connecting, that usually works, though I haven't tried with tmux.
I usually just change TERM to xterm but I've heard that isn't a good way to do it
Also I'd rather not install stuff on every server I ssh into, I've installed it on test servers but wouldn't want to do it on prod
I've never had issues with TERM=xterm
