Today, I was doing some command-line stuff and then this happened:

ls --help|less
Usage: ls [OPTION]... [FILE]...
List information about the FILEs (the current directory by default).
Sort entries alphabetically if none of -cftuvSUX nor --sort is specified.

Mandatory arguments to long options are mandatory for short options too.
ESC]8;;https://www.gnu.org/software/coreutils/manual/coreutils.html#ls-aESC\ESC[1m-a, --allESC[0mESC]8;;ESC\
do not ignore entries starting with .
ESC]8;;https://www.gnu.org/software/coreutils/manual/coreutils.html#ls-AESC\ESC[1m-A, --almost-allESC[0mESC]8;;ESC\
do not list implied . and ..
ESC]8;;https://www.gnu.org/software/coreutils/manual/coreutils.html#ls--authorESC\ESC[1m--authorESC[0mESC]8;;ESC\

It's rendering ls --help with control characters. When I do ls --help|less --raw-control-chars it doesn't show the control characters, and it looks all neat and pretty. Isn't this the opposite of how it's supposed to work?!

Is --raw-control-chars a toggle and some config is causing less to show control characters when I invoke it with no options? If so, where can I find this config and stop this?

This has absolutely no bearing on my work and my life in general except for the fact that I'll go absolutely batshit trying to figure this out, because that's how my brain is. So far, all of my web searches just confirm that less shouldn't be working this way, but they don't give me any way to fix it. Please help me, Lemmy!!!

Yeah use less -r. You can set that in your environment

export LESS="-EX -r"

is what I use.

Capital -R is for most use-cases a safer and better choice than plain -r.

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.
