I was looking for a way to color stderr so when I ran :!make target, I'd see the stderr lines pop up in red so I could more easily see what stopped my build.Inspired by this answer: https://serverfault.com/a/59279, I made the following file:~/.vim/vim_bash:exec 2> >(while read line; do echo -e \e[01;31m$line\e[0m >&2; done)Then I'd run vim via:BASH_ENV=~/.vim/vim_bash vimWhen I'd do :!make target-with-error, the stderr text now shows up as red.  Everything looks right to me.I was wondering if there's a better way to color stderr.  I'm mostly interested in avoiding some gotchas that I haven't thought of with using the exec command in this manner.  Thanks.For those who tried this and like the effect, add let $BASH_ENV=~/.vim/vim_bash to your .vimrc or .vim/vimrc file.
