And one that is set by default many more places than the one that had been set before, changing behavior people have been seeing for a long time, and some of those people did not expect that, nor seem to want it either. > > >> > >> ls(1) on FreeBSD historically honors -an- environment variable for > >> enabling color. > > > > Short history, long history it had no color support at all. > > Color support in ls(1) is now old enough to drink having been > introduced in 2000- I think that's long enough to call it > "historically" here in 2018. ok, but for 25 years that ls has output in b&w even in a colour terminal unless I took action to make it color output. > >> This environment variable is CLICOLOR.

That would help, atleast the annoyed can alias ls ls --color=never. NB: from the GNU ls documentation there is a significant performance impact with having colorls turned on as you now have to stat every file in a directory listing. Is this also true of the BSD colorls? > Thanks, > Kyle Evans -- Rod Grimes rgrimes@freebsd.org
