Karaf colored output
Hi karaf gurus,
Is it somehow possible to disable karaf’s shell colored output?
It seems that karaf’s does not interpret TERM environment variable, because if I connect to karaf either like this “TERM=xterm-old ssh localhost -p 8101” or like this “ssh localhost -p 8101” the output is colored in both cases.
If I connect, to the linux with “TERM=xterm-old” the colored output is disabled.
Best Regards,
Sergey

Hi Ryan, Guillaume
I'd like to use expect tool to automate some karaf tasks, so I'd like the karaf's output to be without ansi color codes and escape sequences to be able to match against "expect tool" expressions easier.
Best Regards,
Sergey

I think that all the colored output is simply additional characters that are sent with the text to display and then it's simply translated. The absence of those additional bytes shouldn't do anything except cause the text to be mono. I use windows all the time and depending on what I use to connect to karaf, I either have extra garbage characters, text with no color or colored text... sshing results in no color either way, never hit a problem.

From a technical pov, it would be easy enough to disable ansi support based on the TERM variable for SSH connections, though i'm not really sure how well karaf would behave.

Hi Sergey,
ok. Did you try to set a "dummy" TERM before launching Karaf:
export TERM=my-dummy-term
bin/karaf
?

JB

Hi JB,
I'd like automate some karaf tasks by means of using linux expect tool, so I'd like the karaf's output to be without ansi color codes and escape sequences to be able to match against "expect tool" expressions easier.
Best Regards,
Sergey

Hi Sergey,
Not sure to follow you: do you want to disable color or you don't have color and you want it ?
did you try rxvt or xterm (to enable color) ?
to disable any "unknown" term should work.

JB
