Hello there someone pointed me to you for problems
with perl
I am a beginner learning perl on my own.
I wrote this script to read a file
#!/ncsu/perl56/bin/perl -w
#purspose reads from a file
use Getopt::Long;
#set up command line to accept file name
my $ret = GetOptions ("f|filename:s");
my $filename = $opt_f || die "Usage: $0 -f filename
\n";
#open file
open (INPUT, "$filename") || die "could not open file
$filename : $!\n";
#start reading from file
while(<INPUT>)
{
chop;
print "Line $. = <$_>\n";
}
#close file
close (INPUT);
However I get this warning when I run it
Name "main::opt_f" used only once: possible typo at
openfile.pl line 9.
What could be the problem.
I used portions of scripts taken from PERL 5 How-to
second edition.
Hope that you can get back to me on this
Sincerely
KWeku Addae-Mensah
