A better way to compare text length percentage?
I have a solution, but it seems labored. I would like to compare strings return a value in percent out of 100.


Such as:

Code:
$ text1='a'; text2='abc'; s1=${#text1}; s2=${#text2}
$ [ "$s1" -gt "$s2" ] && di=$(( (($s1*100) / ($s2+1)) )) || [ "$s2" -gt "$s1" ] && di=$(( (($s2*100) / ($ls+1)) ))
$ echo $di
300

i.e., 'abc' is 300% longer than 'a'


For beginners: s1=${#text1} will return the length of $text1. In this case it would return '1' because it is one character long ('a').


I've looked at the man pages for 'diff' and some others and haven't figured out an easy way that this could be done in a more simple manner; yet, something tells me I'm missing something. I'm repeating the formulas, and I'm wondering if there is perhaps some way to do an inverse of a result... Anyways, it seems redundant.


Ideas?

xdevicebell

XDeviceBell(3X11)														 XDeviceBell(3X11)

NAME

       XDeviceBell - ring a bell on a device supported through the input extension

SYNOPSIS

       Status XDeviceBell(display, device, feedbackclass, feedbackid, percent)
	       Display *display;
	       XDevice *device;
	       XID *feedbackclass;
	       XID *feedbackid;
	       int *percent;

ARGUMENTS

       Specifies  the  connection  to  the X server.  Specifies the device with which the bell is associated.  Specifies the class of the feedback
       with which the bell is associated.  Specifies the id of the feedback with which the bell is associated.	Specifies the volume in the  range
       -100 to 100 at which the bell should be rung.

DESCRIPTION

       The XDeviceBell request causes the server to ring a bell on the specified feedback of the specified device, if possible. The specified vol-
       ume is relative to the base volume for the bell. If an invalid device is specified, a BadDevice error will be returned.	The  feedbackclass
       and feedbackid parameters contain values returned by an XGetFeedbackControl request and uniquely identify the bell to ring.  If a feedback-
       class is specified that does not support a bell, or if a nonexistent feedbackid is specified, or a percent value is specified that  is  not
       in the range -100 to 100, a BadValue error will be returned.

       The volume at which the bell is rung when the percent argument is nonnegative is:

       base - [(base * percent) / 100] + percent

       The volume at which the bell rings when the percent argument is negative is:

       base + [(base * percent) / 100]

       To change the base volume of the bell, use XChangeFeedbackControl.

       XDeviceBell can generate a BadDevice or a BadValue error.

DIAGNOSTICS

       An  invalid  device  was  specified.   The specified device does not exist, or has not been opened by this client via XOpenInputDevice.	An
       invalid feedbackclass, feedbackid, or percent value was specified.
