Code:
let count=0

for i in $*
do
   if [ ! -z "$name" ]; then
      let count+=1
   fi
done

echo $count

Pod::Simple::Checker(3pm)				 Perl Programmers Reference Guide				 Pod::Simple::Checker(3pm)

NAME
Pod::Simple::Checker -- check the Pod syntax of a document SYNOPSIS
perl -MPod::Simple::Checker -e "exit Pod::Simple::Checker->filter(shift)->any_errata_seen" thingy.pod DESCRIPTION
This class is for checking the syntactic validity of Pod. It works by basically acting like a simple-minded version of Pod::Simple::Text that formats only the "Pod Errors" section (if Pod::Simple even generates one for the given document). This is a subclass of Pod::Simple and inherits all its methods. SEE ALSO
Pod::Simple, Pod::Simple::Text, Pod::Checker SUPPORT
