Why compare as text?
Why not perform the comparisons as numeric?
#! /bin/bash
THOLD=5
KKY6=403
if [ $KKY6 -gt $THOLD ]
then
echo $KKY6 "threshold exceeded"
fi
if [ $KKY6 -eq $THOLD ]
then
echo $KKY6 "threshold equaled"
fi
if [ $KKY6 -lt $THOLD ]
then
echo $KKY6 "threshold not yet reached"
fi

xchangepointercontrol
XChangePointerControl(3X11) XLIB FUNCTIONS XChangePointerControl(3X11)
NAME
XChangePointerControl, XGetPointerControl - control pointer
SYNTAX
XChangePointerControl(display, do_accel, do_threshold, accel_numerator,
accel_denominator, threshold)
Display *display;
Bool do_accel, do_threshold;
int accel_numerator, accel_denominator;
int threshold;
XGetPointerControl(display, accel_numerator_return, accel_denominator_return,
threshold_return)
Display *display;
int *accel_numerator_return, *accel_denominator_return;
int *threshold_return;
ARGUMENTS
accel_denominator
Specifies the denominator for the acceleration multiplier.
accel_denominator_return
Returns the denominator for the acceleration multiplier.
accel_numerator
Specifies the numerator for the acceleration multiplier.
accel_numerator_return
Returns the numerator for the acceleration multiplier.
display Specifies the connection to the X server.
do_accel Specifies a Boolean value that controls whether the values for the accel_numerator or accel_denominator are used.
do_threshold
Specifies a Boolean value that controls whether the value for the threshold is used.
threshold Specifies the acceleration threshold.
threshold_return
Returns the acceleration threshold.
DESCRIPTION
The XChangePointerControl function defines how the pointing device moves. The acceleration, expressed as a fraction, is a multiplier for
movement. For example, specifying 3/1 means the pointer moves three times as fast as normal. The fraction may be rounded arbitrarily by
the X server. Acceleration only takes effect if the pointer moves more than threshold pixels at once and only applies to the amount beyond
the value in the threshold argument. Setting a value to -1 restores the default. The values of the do_accel and do_threshold arguments
must be True for the pointer values to be set, or the parameters are unchanged. Negative values (other than -1) generate a BadValue error,
as does a zero value for the accel_denominator argument.
XChangePointerControl can generate a BadValue error.
The XGetPointerControl function returns the pointer's current acceleration multiplier and acceleration threshold.
DIAGNOSTICS
BadValue Some numeric value falls outside the range of values accepted by the request. Unless a specific range is specified for an argu-
ment, the full range defined by the argument's type is accepted. Any argument defined as a set of alternatives can generate this
error.
