Usage of IF/Case statements...*

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


Code:
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 ]

Heap::Elem::Num(3pm)					User Contributed Perl Documentation				      Heap::Elem::Num(3pm)

NAME
Heap::Elem::Num - Numeric Heap Elements SYNOPSIS
use Heap::Elem::Num( NumElem ); use Heap::Fibonacci; my $heap = Heap::Fibonacci->new; my $elem; foreach $i ( 1..100 ) { $elem = NumElem( $i ); $heap->add( $elem ); } while( defined( $elem = $heap->extract_top ) ) { print "Smallest is ", $elem->val, " "; } DESCRIPTION
Heap::Elem::Num is used to wrap numeric values into an element that can be managed on a heap. The top of the heap will have the smallest element still remaining. (See Heap::Elem::NumRev if you want the heap to always return the largest element.) The details of the Elem interface are described in Heap::Elem. The details of using a Heap interface are described in Heap. AUTHOR
