I am getting following error when trying to delete an array element.

"delete argument is not a HASH element or slice at test.pl.."

my $file="test_html";
my @file_lkp=("file1","file2");
for (my $i=0;$i<=$#file_lkp;$i++)
{
   delete $file_lkp[$i] if ($file eq $file_lkp[$i]);
}

It is working in Linux but not in Solaris Thanks for your help
