我在运行一个Perl脚本后有一个输出，它有几行，但我唯一需要的是gatewayName：statusCode：“失败”，ex。
编辑：例如3个网关，2个失败2个成功，我只会收到一封电子邮件。这是一批完成后的输出。我想得到任何一个单一的电子邮件后，所有的批次都做了，或者我可以生活在每批不同的电子邮件告诉哪一个失败。

这是我的代码

my $results = qx/$args/;  ## -----This is when the command is executed.
print $results;

          ###DO I NEED TO DO A FOR LOOP ?? How do I say if it fails look for the gateway?
        for ($results) 
        {

        if  ($results =~ /failed/) {
                #my @array  = split("\n", $results);
                #my $len = @array;
                #my $gw1 = $array[$len-1];
                #my @gw = split(/:/,$gw1);

        push  (@fails, $results);
     

        }
    }
## Send the report via e-mail
if (@fails){
  #  my ($fails) = @_;
#my $gateway=$gw[1];
    my $sendmail = '/sbin/sendmail -t';
#print "this is gateway $gateway";
open (SENDMAIL, "|$sendmail") or die "Cannot open sendmail: $!";
print SENDMAIL "From:" . 'admin@test.com';
print SENDMAIL "\n";
print SENDMAIL "To:" . 'email@gmail.com';
print SENDMAIL "\n";
print SENDMAIL "Subject: " . " Failed IPS Clusters\n";
print SENDMAIL "\n";
print SENDMAIL @fails;

当在列表上下文中使用时，qx返回输出行的列表，而不是所有内容都在一个字符串中。然后可以像往常一样循环：

my @results = qx/$args/;
my ($gateway, $status);
for my $line (@results) {
  if ($line =~ /gatewayName: "(.*)"/) {
    $gateway = $1;
  } elsif ($line =~ /statusCode: "(.*)"/) {
    $status = $1;
  }
}

好的做法是使用词法文件句柄和3-argument form of open：

open my $SENDMAIL, "|-", "/sbin/sendmail -t"
  or die "Unable to open pipe to sendmail: $!\n";

下面是如何从多行字符串中提取内容的示例：

my $output = <<'END';
name: "SMC User"
      domain-type: "domain"
    color: "black"
    statusCode: "failed"
    statusDescription: "Failed"
customFields: null
    gatewayName: "test-gateway"
    revision: "a26546f2-2328-427d-b2f2-8b1411d09acc"
END

my $status_code;
my $gateway_name;
for my $line (split /\n/, $output) {
    if ($line =~ /^\s*statusCode:\s+"([^"]+?)"/) {
        $status_code = $1;
    }
    if ($line =~ /^\s*gatewayName:\s+"([^"]+?)"/) {
        $gateway_name = $1;
    }
}

if ($status_code eq "failed") {
    # Send the report via e-mail
    open (my $SENDMAIL, '|-', '/sbin/sendmail', '-t') or die "Cannot open sendmail: $!";
    #... print headers and subjects as before..
    print $SENDMAIL "$gateway_name failed\n";
    close $SENDMAIL;
}

如果我正确理解了你的问题，那么它是，你在Perl脚本中运行命令$args，并将输出存储在$results中。现在你想处理这个，并得到statusCode和gatewayName的值，以进一步处理。
以下是您可以执行的操作：

use strict;
use warnings;

# Execute the command and capture the output
my $results = qx/$args/;

# Initialize variables to store the extracted values
my $statusCode;
my $gatewayName;

# Split the output into lines and process each line
foreach my $line (split /\n/, $results) {
    if ($line =~ /statusCode: "([^"]+)"/) {
        $statusCode = $1;
    }
    elsif ($line =~ /gatewayName: "([^"]+)"/) {
        $gatewayName = $1;
    }
}

# Print the extracted values
print "Gateway Name: $gatewayName\n";
print "Status Code: $statusCode\n";

# Check if $statusCode is "failed" to send email
if ($statusCode eq 'failed') {
    # your code here to send email
}
