I solved this once, but I cannot remember how I did!
In my child process, I have this:
echo -e "some control chars"
In my parent process, it will show the plain string, without any terminal styling. Isn't there some way to interpret the control chars coming from stdout/stderr of child processes in the parent?
To be specific I have this bash function sourced in the parent:
ql_cyan='\033[1;36m'
ql_no_color='\033[0m'
function ql_log_colors {
echo "sourcing quicklock.sh"
echo -e "${ql_cyan}sourcing quicklock.sh${ql_no_color}";
echo "${ql_cyan}sourcing quicklock.sh${ql_no_color}";
}
export -f ql_log_colors
if I run ql_log_colors in the current shell, I get colors!
however, if I call ql_log_colors from a subshell, no colors will be displayed in the parent, just the plain string "sourcing quicklock.sh".
As you can see, I tried 3 variants of echo command, all just output plain text in the parent, if the echo statements are called from a child.
