Perl脚本帮助|读取文件组,寻找特定匹配

标签: perl file

这是我想要实现的目标。

我有一个perl脚本,它会查找一组直接解析它找到的文件并找到一个特定的字符串。如果找到特定字符串,它会忽略它,如果它找到字符串的第一部分,但第二部分不匹配,则将其写入日志文件。

我坚持使用的部分是如何读取整个文件,并查看整个文件中是否存在该字符串。

有些背景,我试图编写一个读取cisco rancid文件的脚本,并查找sys日志记录详细信息。这些存储在配置中

记录x.x.x.x

其中x.x.x.x是系统日志IP地址。

目前,我可以在文件中读取,逐行检查,并查看该文件是否包含日志x.x.x.x,如果有,则忽略它。

如果它包含日志记录y.y.y.y(其中y是与其应有的IP不同),它将写出日志文件,即设置日志记录,但配置错误。但我不知道我的生活如何让它读取整个文件,如果记录x.x.x.x甚至记录y.y.y.y不存在,写出它没有配置。

脚本位于

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

#Syslog Checker.... V0.0.1

##Config Items
my $basedir = "/home/srelf/Documents/Projects/perl/Configs";
my @verdir  = qw(sw_a);
my $fulldir;
my $configs;
my $loghost = "x.x.x.x";
my $combidir;
use POSIX qw(strftime);
$now_string = strftime "%a%b%e%Y", gmtime;
open FILE, ">>Configchecker.$now_string.txt" or die $!;
print FILE "### Logging Host Settings ###\n";
close FILE;

foreach $combidir (@verdir) {
    $fulldir = "$basedir/$combidir";
    opendir( DIR, $fulldir );
    my @files = grep { $_ ne '.' && $_ ne '..' } readdir DIR;
    closedir(DIR);
    while ( @files > 0 ) {

        $configs = pop @files;

# print "$fulldir/$configs\n"; # used for debug shows current file with full path.
        open FH, "$fulldir/$configs" or die $!;
        @dataarry = <FH>;
        foreach my $line (@dataarry) {

            # Start an if statement, the condition of which is
            # "If this particular line contains logging + IP address."
            if ( $line =~ m/logging \b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b/i ) {

     #then if the line located above contains logging and the log host ignore it
                if ( $line =~ m/logging $loghost/i ) {

                }

   # if the above line contains an ip but it is not the correct ip do the below.
                elsif ( $line =~
                    m/logging \b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b/i )

                {
                    open FILE, ">>Configchecker.$now_string.txt" or die $!;
                    print FILE "$configs\n";
                    print FILE
"Logging for this device is set, but pointing at the wrong host:  $line\n";
                    close FILE;
                }    # End the if condition here.
            }
        }

    }    # End the foreach loop here;
    open FILE, ">>Configchecker.$now_string.txt" or die $!;

      {
         print "Logging for this device is set, but pointing at the wrong host:  $_\n";
      }
   }
