setup

In this case specifically I'm trying to preserve the colors in git status -s when piping it to another command.

Some git commands, diff for instance, and other commands like grep have an option --color=always but git status does not.

question

Is there a way to pipe or capture the output of a command and make it think it is outputting to the xterm shell so it doesn't automatically disable colors?

Answer 1

Here's a script snippet using the colorized output of ls as an example (on Mac OS X 10.6).

# no colored ls output if stdout is a pipe (and not a tty)
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"
