Hi All,

I am new to shell scripting.

I have a variable which holds a numeric value.I have to check whether this variable holds a value between(0- 8),(8-17)(17-24).How do i write this syntax using if in shell scripting.

Thanks
Vignesh

IF u want to use if-Syntax[ksh],

if [ $ur_variable -ge 0 ] && [ $ur_variable -le 8 ]
then
    echo "Num is between 0-8"
    
elif [ $ur_variable -ge 0 ] && [ $ur_variable -le 8 ]
then
    echo "Num is between 9-17"        

elif [ $ur_variable -ge 0 ] && [ $ur_variable -le 8 ]
then
    echo "Num is between 18-24"
fi

Use case for your problem...

case $ur_variable
  "") echo "Not entered"
  [0-8]) echo "Num is between 0-8";break;
  [9-17]) echo "Num is between 9-17";break;
  [18-24]) echo "Num is between 18-24";break;
  *) echo "Non-Numeric or Alphabetic or Spl,chars or Not in range[0-24];break;
esac
