Thats why I prefer functions:
Code:
bigger_value()  { # str1 str2
	[[ ! 2 -eq $# ]] && echo "Usage: $FUNCNAME str1 str2" >&2 && return 1
	echo ${#1} ${#2} | awk '{a=b=$1;($1>$2)?a=$2:b=$2;if(a*b){print int(100/a*b)}}' >&1
	return $?
}

EDIT:
But you still need to figure out a way to 'remove the option' to pass an empty string.
And without knowing how/where you get those strings, we can not help.

How about:
Code:
echo ${#text1} ${#text2} | awk '$1*$2{a=b=$1;($1>$2)?a=$2:b=$2;print int(100/a*b)}'

I prefer to only use functions when I'm going to use them more than once in my code. In this case, it's only used once.

The strings are regular text. So long as the examples as we've used them work, the program will work. As to the empty string, the code to not run if one or more strings are 0 in length works well enough for me.

For those who care, I managed to come up with something more efficient. This code will also output even if there is no text:
Code:
a=${#text1};b=${#text2};echo $((a*b?(a>b?100*a/b:100*b/a):0))
