I'm getting so many of these | Quote: | | xdvi-motif: Warning: Ignoring invalid color name in special `<NULL>' |
that I'm hoping someone has an idea on how to get rid of them.
Thanks,
Fred |

I can not find any package with the name xdvi. I would like to help you but you need to give specifics. Which package is causing this warning? When does this warning occur? Is this warning causing any issues for you? (Is the goal to mute the output rather than fix it.)
Please post those details and I'll try my best to help.

Since xdvik is a gui application. Where are you seeing this error message? Are you launching the application from the console? Also, is the error causing you any real trouble, or is it just an annoyance? If you tell me where you are seeing the warning, I should be able to help.

Very good! I'm running xdvi from a terminal. That's where the messages appear. It is really no more than an annoyance, but it means the terminal is not much use for anything else as their are a lot of these messages.
Thanks. |

@Fred Krogh,
Description of /app-text/xdvik is:
DVI previewer for X Window System.
IMHO it's not meant to be used in a terminal.

| Thanks. I guess that solves the problem sort of. I suppose the error messages are still being generated, they are just not visible. I can certainly work around this. |

| If the messages are not meant to be shown, why write them at all? They may not be a problem for this user, but they presumably indicate some sort of problem for some use cases. |

Even though this isn't necessarily a solution to this problem, It's still useful to know.
If you want to mute all output of a program in the terminal you can use this.
| Code: | | /usr/bin/someprogram >/dev/null 2>/dev/null & |
The first argument (>/dev/null) forwards all the regular output (info, status, etc.) to /dev/null, a special device that eats all input. (Eats and destroys it that is.) The second (2>/dev/null) tells it to forward all type two output (errors) to /dev/null. The & at the end allows you to do other things in the terminal while the program runs by forcing it to the background.
Happy gentooing!  (Not sure if that is a thing...)
PS: Before anyone corrects me: Yes, I am aware there is a better syntactical way to write this (>/dev/null 2>&1) but it is easier to explain like this.

Maybe, though anytime I launch a graphical application from a terminal I almost always see warnings. (I'm not proud, but I used to do that alot...  ) For some applications, I see tons of them. Most of the time they really are harmless. I've never once had a warning become an issue. Some developers just include a lot of information in there logs for debugging purposes. (Something which I appreciate very much.)
