散列哈希Perl代码问题

问题描述

我试图使用perl代码从下面的命令中存储信息，

I tried to store information from below command using perl code,

假定此命令的输出如下，

Assume the output from this command as below,

AMQ8409: Display Queue details.
   QUEUE(SYSTEM.RETAINED.PUB.QUEUE)        TYPE(QLOCAL)
   ACCTQ(QMGR)                             ALTDATE(2016-08-01)
   ALTTIME(18.33.20)                       BOQNAME( )

   QUEUE(SYSTEM.SELECTION.EVALUATION.QUEUE)

   CURDEPTH(0)                             CUSTOM( )
   IPPROCS(0)                              MAXDEPTH(999999999)

AMQ8409: Display Queue details.
   QUEUE(SYSTEM.SELECTION.VALIDATION.QUEUE)
   TYPE(QLOCAL)                            ACCTQ(QMGR)
   ALTDATE(2016-08-01)                     ALTTIME(18.33.20)
   BOQNAME( )                              BOTHRESH(0)
   CLWLRANK(0)                             CLWLUSEQ(QMGR)
   CRDATE(2016-08-01)                      CRTIME(18.32.37)
   CURDEPTH(0)                             CUSTOM( )
   IPPROCS(0)                              MAXDEPTH(999999999)

因此，对于每个输出(从中我们可以看到3个)，我编写了一个代码来存储关于每个MQ队列名称的QUEUE，CURDEPTH和MAXDEPTH的信息.

So, for each of this output (from we can see there are 3), I wrote a code to store information about QUEUE, CURDEPTH and MAXDEPTH for each MQ queue name.

我的代码如下，

#!/usr/bin/perl

use warnings;
use strict;

my %QM;
my $qm = 'MQ_NAME';

open (CHS_OUT, "echo 'dis ql(*) all'|runmqsc $qm|");

while (<CHS_OUT>) {

        my ($QUEUE, $QName) = / ( QUEUE ) \( ( [^)]+ ) /x;

        if ( my ($item, $value)
        = / ( CURDEPTH | MAXDEPTH ) \( ( [^)]+ ) /x )
        {
                $QM{$QName}{$item} = $value;
        }
}

foreach my $Que (sort keys %QM) {
        foreach my $v (keys %{ $QM{$Que} }) {
                print "$Que : $v = $QM{$Que}{$v} \n";
        }
}

我已经尝试将$ QName设置为全局，但仍然无法解决问题，此代码仍然存在错误.

I already try to make the $QName as global still cannot help, there are still error from this code.

我的代码的输出:

Use of uninitialized value $QName in hash element at mq_queue_5.pl line 25, <CHS_OUT> line 7353.
Use of uninitialized value $QName in hash element at mq_queue_5.pl line 25, <CHS_OUT> line 7361.
Use of uninitialized value $QName in hash element at mq_queue_5.pl line 25, <CHS_OUT> line 7384.
Use of uninitialized value $QName in hash element at mq_queue_5.pl line 25, <CHS_OUT> line 7392.
 : CURDEPTH = 0
 : MAXDEPTH = 999999999

我已经停留了好几天，已经做了很多更改，但仍然无济于事.

I already stuck for multiple days, already make a lot of changes but still does'nt help.

推荐答案

您必须检查QName是否匹配并记住它:

You have to check if the QName is matched and remember it:

#!/usr/bin/perl

use warnings;
use strict;

my %QM;
my $qm = 'MQ_NAME';

open (CHS_OUT, "result.txt");
my $QName;
while (<CHS_OUT>) {
        my ($QUEUE, $QName1) = / ( QUEUE ) \( ( [^)]+ ) /x;

        if ($QName1) {
                $QName=$QName1;
        }
        if ( my ($item, $value)
        = / ( CURDEPTH | MAXDEPTH ) \( ( [^)]+ ) /x )
        {
                $QM{$QName}{$item} = $value;
        }
}

foreach my $Que (sort keys %QM) {
        foreach my $v (keys %{ $QM{$Que} }) {
                print "$Que : $v = $QM{$Que}{$v} \n";
        }
}

输出:

SYSTEM.RETAINED.PUB.QUEUE : CURDEPTH = 2
SYSTEM.RETAINED.PUB.QUEUE : MAXDEPTH = 999999999
SYSTEM.SELECTION.EVALUATION.QUEUE : CURDEPTH = 0
SYSTEM.SELECTION.EVALUATION.QUEUE : MAXDEPTH = 999999999
SYSTEM.SELECTION.VALIDATION.QUEUE : MAXDEPTH = 999999999
SYSTEM.SELECTION.VALIDATION.QUEUE : CURDEPTH = 0
