Description:
1.
BASH$ { echo 111; echo 222 ;} 2> >( echo -en "\e[01;31m" >&2; read line; echo
"$line" >&2; echo -en "\e[0m" >&2 ) >&2
111 # result is one line and red-colored that is expected behavior.
2.
# If i remove ">&2" that is at the end of command
# result is two lines with white-colored that is also expected behavior.
BASH$ { echo 111; echo 222 ;} 2> >( echo -en "\e[01;31m" >&2; read line; echo
"$line" >&2; echo -en "\e[0m" >&2 )
111 # white colored
222 # white colored
3.
# If i add external "date" command in the middle of two echo commands
# result is in red-colored after external date command output
# i think there must be no red-colored because { echo 111; date; echo 222 ;}
only direct to stdout
BASH$ { echo 111; date; echo 222 ;} 2> >( echo -en "\e[01;31m" >&2; read line;
echo "$line" >&2; echo -en "\e[0m" >&2 )
111 # white colored
