我正在阅读别人写的Perl脚本,我对Perl不太熟悉所以有人能让我知道前三行做了什么？
my $ref = do($filename);
$ref != 0 or die "unable to read/parse $filename\n";
@varLines=@{$ref};
foreach $ord (@varLines)
{
# code here
}
在获取命令行参数设置$filename之后,这是在程序的开头
传递给此脚本的文件格式为
[
{
"Key1" => "val1","key2" => " "A",},{
"Key3" => "val2","key4" => " "B",]
