Compare a blob of datas size while gzipped and base64'd. I use this when I'm packing things into binaries with base64 and gzip to calculate the benefits of gzip vs the extra overhead of base64.

gzipCompare.sh

function gzipCompare() {
	_TARG="$1"
	echo -n "Calculating gzip differences for"; echo -e " \e[1;32m$_TARG\e[0m"
	_OG=$(cat "$1" | wc -c)
	_B6=$(cat "$1" | base64 -w 0 | wc -c)
	_GZ=$(cat "$1" | gzip -9 | wc -c)
	_G6=$(cat "$1" | gzip -9 | base64 -w 0 | wc -c)
	echo "----------------------------------------"
	echo -n "Original: " | colorize white --attr="bold";
		echo "$_OG bytes"
	echo -n "Base64'd: " | colorize blue --attr="bold";
		echo -n "$_B6" | colorize blue; echo " bytes"
	echo -n "Gzippe'd: " | colorize yellow --attr="bold";
		echo -n "$_GZ" | colorize yellow; echo " bytes"
	echo -n "Gzip+B64: " | colorize magenta --attr="bold";
		echo -n "$_G6" | colorize magenta; echo " bytes"
	echo "----------------------------------------"
}
