Question

我正在尝试将一个阵列单列匹配到另一个阵列并打印这些行。但它一片空白。不知道哪里出错了。个别元素正在印刷...... 寻求一些帮助。代码如下;

#!/usr/bin/perl
use strict;
use warnings;
#use File::Find;

#!/usr/bin/perl
use strict;
use warnings;

# Define file names and its location
my $input = $ARGV[0];       # requires input raw DS8K PU file

############################################################################################
# Section to read config file and extract volumes of user inserted volumegroup
############################################################################################
my $input_PU_config = $ARGV[1];   # requires input config file

my @vg_vol_id;    # defining variable for config file
my @interval_data = ('start_time','length');

print "\nEnter the volume group number you need to work upon: ";    # I insert number as 8 and it greps "V8" required line from the config file
chomp (my $vol_grp_number = <STDIN>);

open (CONFIG_INFILE,"$input_PU_config_file") or die "Could not open: $!";
while (<CONFIG_INFILE>)
    {
     if (/ FB 512 / && (/ V$vol_grp_number,/ || /,V$vol_grp_number / || / V$vol_grp_number /))  ## If device is part of multiple VG
        {
         my @volume_id = split(/\s+/,$_);
         push @vg_vol_id, "0x$volume_id[1]";
         #print "0x$volume_id[1]\n";
        }
    }
unshift @vg_vol_id,@interval_data;
#print "@vg_vol_id\n";
close (CONFIG_INFILE);
############################################################################################
# Grab the only vols stats for different intervals and put it in a file
open (INFILE,"$input_file") or die "Could not open: $!";
open (OUTFILE,">$output_file") or die "Could not open: $!";
while (<INFILE>)
    {
     if (/^volume stats/ .. /^$/)
        {
         print (OUTFILE "$_");
        }
    }
close (INFILE);
close (OUTFILE);
###############################################################################################
# the parsed file is stored as @PU_file array element
open (PARSED_PU_FILE,"$output_file") or die "Could not open parsed file: $!";
my @PU_file = <PARSED_PU_FILE>;
###############################################################################################
foreach my $PU_file_line (@PU_file)
    {
            #chomp ($PU_file_line);
            #print "$line\n";
            foreach my $line (@vg_vol_id)
                    {
                            chomp ($line);
                            #print "$line\n";
                            if ( $line =~ m/^$PU_file_line/)
                            {
                                    print "$PU_file_line\n";
                            }
                    }
                    #print "======================\n";
    }
close (PARSED_PU_FILE);

输出空白。

Answer 1

更改脚本末尾的条件

$line =~ m/^$PU_file_line/

到

$PU_file_line =~ /^$line/

将所需的数组元素与perl中的另一个数组元素匹配
