Summary: XLOG: color ANSI code not usable for colorize system log

Initial Comment:
In background mode I'm trying to colorize openser logs.

I use XLOG with the syntax $(Cxx) and so and works nice in foregorund mode:

  xlog("L_INFO", "$(Csc)$rm $ru$(Cxx)\n");

But ni background mode it generates logs like:

  ^[[0;30;46mINVITE sip:500 at domain.org


I wonder why it doesn't generate correct ANSI code:

  \033[0;30;46m  <-- correct ANSI code
instead of:
  ^[[0;30;46m

If it would generate \033[0;30;46m (correct ANSI code) then I could colorize the log file using multitail and other colorize solutions that understand ANSI code.

Then, why the following command in Bash terminal print "HELLO" in color:

  echo -e "\033[0;30;46mHELLO"

while this one:

  echo -e "^[[0;30;46mHELLO"

prints ^[[0;30;46mHELLO with no color at all?

Thanks for your response.

\033 and ^[ are the same code that corresponds to ESC (0x1b). It should
work with either one, they're just different notations of the same thing.
