解压缩 log.gz 个文件

Uncompress log.gz files

我想解压多个 log.gz - 昨天的文件。

代码:

use strict;
use warnings;
use 5.010;
use IO::Uncompress::Gunzip qw(gunzip $GunzipError) ;
use Time::Local;

#yesterday
my ($sec, $min, $hour, $mday, $mon, $year) = (gmtime())[0..5];

my $yesterday_midday=timelocal($sec,$min,$hour,$mday,$mon,$year) - 24*60*60;

($sec, $min, $hour, $mday, $mon, $year) = localtime($yesterday_midday);


my $path = sprintf "..\..\history\%d\%02d\%02d\*.log.gz",$year+1900, $mon+1, $mday;
print("PATH: $path\n");

gunzip '<path>' => '<#1.log>' #unzip all .log.gz files
        or die "gunzip failed: $GunzipError\n";

错误:

Max wild is #0, you tried #1 at D:/Perl64/lib/IO/Uncompress/Base.pm line 545

您需要扩展标量 $path. 在您的情况下,您要告诉 gunzip 将名为 path 的文件解压缩到通配符输出中。该错误告诉您 字符串 "path" 不包含任何通配符 ,但您指的是匹配的通配符(它不存在,因为没有通配符"path" 字符串).

试试这个:

gunzip "<$path>" => '<#1.log>' #unzip all .log.gz files
        or die "gunzip failed: $GunzipError\n";
