I dont have an OSX to test but... I know that in TTY in linux the bold text is also leaved with a different colour.

Do you know what is the "control code" used in OSX to return the bold color to the default?

@jristz same control code as other POSIX terminals - I've dealt with this before, a few google searches should come up with the reset escape

I'm testing here in a linux tty and in a unix terminal but no one left the the terminal bold when I use help.

In theory the standard control code showl work but I dont get the problem.

Do you mentioned that his happend on OSX, right? so you you can share some screenshoot or the control code used in the OSX terminal to clean the blodness (just to test that here you know, testing to reach out of the issue)

Does OSX have a tput command? If yes you can use something like tput sgr0 for resetting, tput bold for bold.

cb="$(tput bold)"
cc="$(tput sgr0)"

# Then use them
echo "${cb}BOLD${cc} and normal."

Yeah, tput sgr0 works on Mac 👍

Looking at the node.js world, they use 22 instead, saying "21 isn't widely supported and 22 does the same thing"

I confirm that changing it to 22 fixes the bug:

I tested it and I dont find problem...
