If condition is not working and getting error
Hi Team,

If condition is not working properly and getting below error

Code:
# ./score1.sh
Enter your score [0-100%] ('q' for quit): 102
Enter your score [0-100%] ('q' for quit): q
./score1.sh: line 9: [: q: integer expression expected
Average is: 102%.
Exit.

Actual code

Code:
# Calculate the average of given number.
SCORE=0
AVERAGE=0
SUM=0
NUM=0
while true; do
echo -e  "Enter your score [0-100%] ('q' for quit): \c "
read SCORE;
if [ $SCORE -lt 0  -a $SCORE -gt 100 ]; then
echo "Give correct range "
elif [ $SCORE == q ]; then
echo "Average is: $AVERAGE%."
break
else
SUM=$[$SUM + $SCORE]
NUM=$[$NUM + 1]
AVERAGE=$[$SUM / $NUM]
fi
done
echo "Exit."


Thanks
Torrid.

tis_cond_destroy

tis_cond_destroy(3)					     Library Functions Manual					       tis_cond_destroy(3)

NAME

       tis_cond_destroy - Destroys the specified condition variable.

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <tis.h>

       int tis_cond_destroy(
			  pthread_cond_t  *cond);

STANDARDS

       None

PARAMETERS

       Address of the condition variable (passed by reference) to be destroyed.

DESCRIPTION

       This routine destroys the condition variable specified by cond.	After this routine is called, DECthreads may reclaim internal storage used
       by the condition variable object. Call this routine when a condition variable will no longer be referenced.

       The results of this routine are unpredictable if the condition variable specified in cond does not exist or is not initialized.

       For more information about actions when threads are present, refer to the pthread_cond_destroy(3) description.

RETURN VALUES

       If an error condition occurs, this routine returns an integer value indicating the type of error.  Possible return values are  as  follows:
       Successful  completion.	 The  object  being  referenced  by  cond  is  being  referenced  by  another  thread  that is currently executing
       tis_cond_wait(3) on the condition variable specified in cond.  (This error can only occur when threads are present.)  The  value  specified
       by cond is not a valid condition variable.

ERRORS

       None

RELATED INFORMATION

       Functions: tis_cond_broadcast(3), tis_cond_init(3), tis_cond_signal(3), tis_cond_wait(3)
