是否有人能够快速查看我的代码并尝试找出我没有看到的内容。我此时遇到了Perl调试器的麻烦，所以这不是一个选项，直到我修复它（在调查过程中）。这是代码：
## Special Variables:
my @args = ();
my $spcl_dir = "$dir_root\\specialprocessing";
my $spcl_log = 'C:\Dad\Eclipse\Repositories\tiffinfo\!specialprocessing.log';
open(FILE, $spcl_log) || die "Couldn't open $spcl_log: $!\n";
for (my $i = 0 ; $i < 5 ; $i++) {
my $dummy = <FILE>;
}
print "\n$spcl_log\n"; # delete me
while (<FILE>) {
print "DEBUG START\n";
my (@fields) = split /;/;
my $filename = $fields[0];
print "Processing $filename";
print "DEBUG END\n";
}
## Copy process
print "\nStarting the copy process over to $spcl_dir:\n";
while (<FILE>) {
print "DEBUG START!\n";
my (@fields) = split /;/;
my $filename = $fields[0];
print "Copying $filename";
if (copy("$dir_root\\$filename", "$spcl_dir\\$filename")) {
print " - Success!\n";
}
else { print " - Failure!\n"; }
}
close(FILE);
## Confirmation of file copy
print "Everything look OK?: ";
chomp(my $confirmcopy = <STDIN>);
if ($confirmcopy =~ /^y|^yes/i ) {
print "\nAttempting to remove original files.\n";
## Original file deletion process
open(FILE, $spcl_log) || die "Couldn't open $spcl_log: $!\n";
for (my $i = 0 ; $i < 5 ; $i++) {
my $dummy = <FILE>;
}
while (<FILE>) {
my (@fields) = split /;/;
my $filename = $fields[0];
print "Attempting to remove: $filename";
if (unlink("$dir_root\\$filename")) {
print " - Success!\n";
}
else { print " - Failure!\n"; }
}
close(FILE);
}
else { print "Will do, exiting."; exit; }
## Conversion process
print "\nAttempting to convert the files.\n";
open(FILE, $spcl_log) || die "Couldn't open $spcl_log: $!\n";
for (my $i = 0 ; $i < 5 ; $i++) {
my $dummy = <FILE>;
}
while (<FILE>) {
my (@fields) = split /;/;
my $filename = $fields[0];
print "Starting conversion on $spcl_log\n";
@args = ("$tiffinfo_path", "$spcl_dir\\$filename", "/bpp=2", "/tifc=4", "/convert=$dir_root\\$filename", "/killmesoftly", "/silent");
system(@args);
unlink("$spcl_dir\\$filename");
}
close(FILE);
所需的输出如下：
Irfanview Found.
Directory exists. Continuing...
Starting the copy process over to c:\dad\tiffs\specialprocessing:
Copying filename2.tif - Failure!
Everything look OK?: n
Will do, exiting.
c:\Dad\Eclipse\Repositories\tiffinfo>perl c:\Users\Administrator\Desktop\exectif
finfo.pl
Irfanview Found.
Directory exists. Continuing...
Starting the copy process over to c:\dad\tiffs\specialprocessing:

Everything look OK?: y
Attempting to remove original files.
Attempting to remove: filename2.tif - Failure!
Attempting to convert the files.
Starting conversion on filename2.tif
这显然会有所不同，但你得到了图片。我遇到的问题是，每次我似乎点击while循环，没有任何处理，没有代码工作。我甚至尝试过简单的调试，比如print语句，看看代码实际得到了多少，而while语句执行时只有NOTHING。
OUTPUT I RECEIVE（我必须将CTRL-C退出程序，因为它不会自行退出）：
C:\Dad\Eclipse\Repositories\tiffinfo\!specialprocessing.log
Starting the copy process over to c:\dad\tiffs\specialprocessing:
Everything look OK?: y
Terminating on signal SIGINT(2)
while循环之前的print语句打印“spcl_log”变量，该变量为：
C:\Dad\Eclipse\Repositories\tiffinfo\!specialprocessing.log
日志文件的内容（前五行总是被跳过 - 这就是虚拟循环的作用）：

先谢谢了！ ：）
答案 0 :(得分：2)
您的DEBUG START，DEBUG END while循环正在占用文件中的所有数据 - 然后您希望主循环从同一文件中读取新数据。
或者：
或者：
您所需的输出并非显示在所显示的代码中 - 特别是第一行似乎没有任何代码可以打印它。
你的代码有相同的代码写出3次 - 跳过5行并分割出文件名的东西。在SO 4272615的答案中，您获得了一组函数，这些函数将为您提供一个包含要处理的文件名列表的数组。使用功能 - 它们使代码更易于管理！
我发现您的代码不包含“use strict;”或“use warnings”;专家一直使用它们以确保它们不会出错，初学者需要一直使用它们以确保它们不会出错。碰巧的是，它抛出的唯一问题是“未声明的变量”，所以你的代码也不错。
当我运行代码（被黑客攻击，因此目录适合我的机器）时，第一个DEBUG循环运行并占用数据;因此第二个循环没有报告。如果我试图让它运行，那么它会抱怨找不到函数main::copy。据推测，这可以通过添加“use File::Copy;”来解决，但如果您发布您正在使用的实际代码，而不是一个与之相关的代码，则会有所帮助。
即使在Windows上，最好不要在路径名中使用“\\”;你可以在其中使用'/'，而o / s非常开心;它是cmd.exe，它不喜欢斜杠而不是反斜杠。
WFM下面的代码 - 适用于我（测试环境：MacOS X 10.6.5，Perl 5.13.4）。我从上一个问题创建了一个文件'data.file'。我创建了子目录'safe'，'src'和'dst'，并在'safe'中创建了空文件'filename2.tif'，'filename4.tif'，'filename6.tif'，'filename8.tif'。然后我将文件从'safe'链接到'src'，这样我就可以轻松地重新运行脚本，尽管它取消了输入文件的链接。
ln safe/* src
我还创建了一个脚本'converter'：
echo "$0 $@"
程序的输出是：

system）。unlink是否成功。$!”。use Carp;”和carp以及croak代替warn和die。get_file_list()用于获取文件列表 - 只需一次。$file而不是FILE。open的三个参数形式，这是最可靠的形式。open周围的括号，'||'是正确的;如果你在重写中省略了括号，那么'或'是必要的。）foreach循环遍历文件列表。exit的显式状态为0（成功）。答案 1 :(得分：2)
您设置了输入分隔符（在第190行）：
$/ = "TYPE:\n";
答案 2 :(得分：0)
嗯，你显然没有从<FILE>收到任何回复。
也许您在某处更改了输入记录分隔符（$/）？
要调查，请将for循环扩展为：
for (my $i = 0 ; $i < 5 ; $i++) {
my $dummy = <FILE>;
print $dummy;
}
这应该会让你很清楚这里发生了什么。
另外，考虑读取数组中的文件（my @lines = <FILE>;），因为您不止一次使用该信息。
