Like echo, but in the --color that grep uses when that option is given

echoColor.sh

#!/bin/sh

#handle no input - just fire echo and exit
if [ "$#" -eq 0 ]; then
        echo
        exit
fi

#concat params like echo does
str="$1"
shift
for var in "$@"
do
        str=$str" "$var
done

#use a match all grep to with --color to color the output
echo "$str" | grep --color -o ".*"
