Re: [gentoo-user] How do I get rid of colors (console and xterm)?
XTerm also includes a -cm option (colorMode resource) for ignoring control sequences that affect color.

Try changing your terminal type (TERM environment variable) to something that doesn't support color. I'd suggest VT100. Try the following in a terminal session and see if that helps. export TERM=vt100 See attached a pic of an xterm window, which I cannot read easily. (I'm color-blind, so this might enhance the problem.) You can also redefine the colors in XTerm so that anything that thinks it's using a given color number is actually using whatever RGB value you set. Thus you can alter the colors to whatever you want. -- Grant. . . . unix || die

Your term looks rather low contrast with that rather bright dark greenish background... I use 'grey5' ;) You can also adjust the colours see 'man 5 color.map' and /etc/portage/color.map. And/or even patch emerge's output routines (I think there's some stuff that has no variable in color.map, and which is hard to read on grey5).

I will >check out your suggestion. AFAIK that mostly depends on what you use as pager for man, e.g. less. Controlling formatted output -P pager, --pager=pager Specify which output pager to use. By default, man uses less -s. This option overrides the $MANPAGER environment variable, which in turn overrides the $PAGER environment variable. It is not used in conjunction with -f or -k. So, have a look at the MANPAGER and PAGER variables if they're set. If they are, have a look at the config of that pager, else at that of 'less(1)'. Oh, and have a look at your terminal options. E.g. use 'xterm -cm' instead of 'xterm'... (or set the according Xresource) and all you get is black & white ;) HTH, -dnh -- # Mmm, yes. cookies my precious! Mmm, yes downloads it # is!

Re: [gentoo-user] How do I get rid of colors (console and xterm)?
Thanks Ralph. In the meanwhile I had found out the "NOCOLORS" setting in make.conf which works for "emerge". man pages in color are the other most important problem right now. I will check out your suggestion. regards, chris On 7/4/19 9:19 PM, Ralph Seichter wrote: * Christian Groessler: My question is how do I get rid of colors in "emerge", "man" and other command line programs. The methods vary between command line tools. You can for example disable the 'manpager' USE flag for sys-apps/man-db. The manual page for emerge mentions different methods (search for "--color"). Depending on the terminal software you use, you might be able to select monochromatic colour profiles (iterm2 for macOS does support this). -Ralph

[gentoo-user] How do I get rid of colors (console and xterm)?
Hi, I'm new here. My question is how do I get rid of colors in "emerge", "man" and other command line programs. I managed to do in the shell (bash), but I'm somehow lost how to change it elsewhere. In "vi" I know of "syn off". See attached a pic of an xterm window, which I cannot read easily. (I'm color-blind, so this might enhance the problem.) regards, chris
