perl脚本显示错误：找不到文件

Question

我试图运行下面的perl脚本，但它显示一个错误。所需的文件是我把它们放在脚本文件的同一目录中。

#! /usr/bin/perl

电话： perl的script.bat门户

结果： 无法打开文件portal_perParamDefault_URLs.txt

Answer 1

Windows路径可以用斜杠，而不是反斜杠，或更好地利用File::Spec来处理它处理像：

my $full_path = File::Spec->catpath("D", $app, $fileName) 
open(inputFile, $full_path) or die $!; 

Answer 2

你的编码是可怕的，但我建议你的问题的答案可能是你的意思是_perParamDefault_URLs你有_perParamDefaut_URLs？

之前要求别人饶恕自己的时间来帮助你，请有足够周到正确格式化您的代码，以便它是可读的，加use strict和use warnings你的程序的顶部，所有变量的使用my接近申报他们的第一个使用点。

您还应该使用词法文件句柄，open的三参数形式，并将$!变量添加到您的骰子字符串的内容中。一个样板调用open应该像

open my $fh, '<', $filename or die "Unable to open '$filename': $!";
