[Help-bash] How to preserve ansi color when piping (across platform)?

[Peng Yu]

Hi,

The following example shows how to preserver ansi color when piping.
But script is not compatible between mac and linux. Is there a way
that works across platform?

ls -G /
ls -G / | cat
script -q /dev/null ls -G / | tr -d '\r' | cat

# write output of script command to a variable
var="$(script -q /dev/null ls -G / | tr -d '\r' | cat)"
echo "$var"
