在Windows 7中使用ActivePerl，@ ARGV为空 [英] @ARGV is empty using ActivePerl in Windows 7

问题描述

我有以下Perl脚本.我正在尝试使用ActivePerl在Windows 7中运行它:

I have the following Perl script. I am trying to run it in Windows 7 using ActivePerl:

#!c:\Perl64\bin\perl.exe -w

use strict;

my $mp3splt_exe = 'c:\Program Files (x86)\mp3splt\mp3splt.exe';

my $mp3splt_args = '-o "@n @f" -g "r%[@o @N]"  -f -t 6.0';

print @ARGV;
my $filename = $ARGV[0];

print "$mp3splt_exe $mp3splt_args $filename\n";

(如您所见，我正在尝试为mp3splt创建包装器:-))

(as you can see, I am trying to create a wrapper for mp3splt :-) )

当我这样运行时:

C:\ Program Files(x86)\ mp3splt> run_mp3splt.pl a

C:\Program Files (x86)\mp3splt>run_mp3splt.pl a

我明白了:

Use of uninitialized value $filename in concatenation (.) or string at C:\Program Files (x86)\mp3splt\run_mp3splt.pl line 12.
c:\Program Files (x86)\mp3splt\mp3splt.exe -o "@n @f" -g "r%[@o @N]"  -f -t 6.0

因此，首先，当我print @ARGV时，什么都不会打印，其次，当我分配$filename = $ARGV[0]时，$filename是undef，所以我得到了警告.

So, first of all, when I print @ARGV, nothing gets printed, and second of all, when I assign $filename = $ARGV[0], $filename is undef, so I get the warning.

那么...我在做什么错?为什么不将命令行参数传递给脚本?

So... what am I doing wrong? Why isn't the commandline parameter being passed to the script?

推荐答案

我很确定Windows 7无法理解shebang行.如果您使用perl run_mp3splt.pl a运行此操作，会发生什么情况?

I'm pretty sure Windows 7 doesn't understand the shebang line. What happens if you run this with perl run_mp3splt.pl a?
