Top Forums Shell Programming and Scripting if statement - how can I do 2 arguments? Post 302184804 by Darklight on Sunday 13th of April 2008 05:30:49 AM

firstly, thankyou for your reply.

I should have included some of my code for you to understand what Im on about..

if I use your method, and I have no arguments it skips the first if statement.
basically i want the first if statement to be "if no searchMonth or searchyear, then"

Cheers for your help

Code:
	#if no arguments entered
	if [ $# = 0 ]; then

		echo "Invalid Arguments Entered." 
		echo 
		echo "Usage of this program defined with either of the following inputs:"
		echo "sh programName Month Year"
		echo "sh programName Month"
		echo "sh programName Year"
		echo 
		echo "Full month and year inputs (eg: March 2004) can be used, abbreviation is also a valid input (eg: Mar 04)"
		echo 
		exit
			
	
	elif [ -z $searchMonth ]; then
	
		for (( i=0; i<12; i++))
		do	
			#string comparison
			if [ "$2" = ${month[$i]} -a "$3" = "$searchYear" ]; then
			
				monthCount[$i]=`expr ${monthCount[$i]} + 1`
			
			fi		
				
		done	
		
		print=1	
	
	#if no searchYear entered		
	elif [ -z "$searchYear" ]; then
		
		for (( i=0; i<"${#year[*]}"; i++))
		do		
			#string comparison
			if [ "$2" = "$searchMonth" -a "$3" = "${year[$i]}" ]; then
			
				yearCount[$i]=`expr ${yearCount[$i]} + 1`
				
			fi
			
		done
	print=2
