Check file from multiple files is empty using awk

I am passing multiple files in awk & since one of the file is empty(say file3) so the same gets skipped & logic goes for toss. Need suggestion/help in checking and putting additional checks for the same


Code:
awk -F,  'FNR==1 {++filecounter}
filecounter==1 {KRL[$1]=$2;next}
filecounter==2 {GUJ[$1]=$2;next}
filecounter==3 {DEL[$1]=$2;next}
filecounter==4 {UPW[$1]=$2;next}
{
if($1 in KRL)
print "FOUND IN KRL"
else if($1 in GUJ)
print "FOUND IN GUJ"
else if($1 in DEL)
print "FOUND IN DEL"
else if($1 in UPW)
print "FOUND IN UPW"
else
print "Not Found" 
}
' File1 file2 file3 file4 mainfile

COMMAND-NOT-FOUND(1)					    http://en.opensuse.org/Sco					      COMMAND-NOT-FOUND(1)

NAME
command-not-found - A command-not-found handler SYNOPSIS
command-not-found {binary_name} {repository} ARGUMENTS
The following arguments are required: binary_name The name of binary you are looking for. repository The name of repository for search. For most cases, use zypp DESCRIPTION
command-not-found handler is designed to tell users which package contains a missing command. The handler is integrated to bash(1) and zsh(1) shells and is not necessary to call it directly. Just type a name of the command in your favourite shell and you'll get a result. If you consider c-n-f handler useless, just add unset command_not_found_handle to your profile or remove the command-not-found package. Handler doesn't call the command-not-found binary directly, it only prints info about it. If you want to invoke it automatically, just add export COMMAND_NOT_FOUND_AUTO=1 to your bash profile. EXAMPLE
: NORMAL USAGE For example you want to try blender, because you have heard that is an amazing program. So just type blender in shell: $ blender You get the following output: The program 'blender' can be found in the following package: * blender [ path: /usr/bin/blender, repository: zypp (openSUSE 11.1-0) ] Try installing with: sudo zypper install blender bash: blender: command not found SEE ALSO
