Works, very small, no complaints.
The Following code does not work correct when w=1 or w=2 or w=3 or w=4 "if [ "$W" -le 05 ];then REMW=`expr 48 + $W` elif [ "$W" -lt 15 ];then REMW=0`expr $W - 5` else REMW=`expr $W - 5` fi" For each above case, the "if" condition and "elif" condition both works and the value of REMW which is calculated in "if" condition gets replaced in the "elif" condition and becomes negative. This issue needs to be correct
Easy, stable usefull, quick! Great job!
