Bash command result text format mismatch

team!
I want to execute bash command into variable.

COMMAND="systemctl status wazuh-manager --no-pager"
NEWMESSAGE="$($COMMAND)"
if [[ -n $NLINES ]]; then
     $NEWMESSAGE | tail -n $NLINES
fi
if [[ -n $OUTPUTFILE ]]; then
    echo -e $NEWMESSAGE |& tee -a $OUTPUTFILE
fi

I have output like this.
Single line with no color text.

How to save text format?

>Solution :

To keep the format and pass the color format of the output of systemctl status .... you can use;

$ var="$(SYSTEMD_COLORS=1 systemctl status wazuh-manager.service)"
$ echo "$var"

The color as well as the format wil now be preserved
