1つのtxtファイルを読み取り、いくつかのキーワードを検索するという1つのタスクを自動化しようとしています。そのキーワードを取得するとすぐに、そのキーワードを取得した行から指定された行(以下)をいくつか印刷します。

私は自分のコードを書きましたが、行の束ではなく単一の行を印刷できます。

#!/usr/bin/perl 
use strict;
use warnings;
open(my $fh,"<","dmesg_TZ.txt") or die"can not open the file";
open(my $fh_01,">","dmesg.txt") or die"can not open the file";
my @lines=<$fh>;
close($fh);
my @Kenel_panic_lines;
for(my $i=0;$i<=$#lines;$i++){
    if($lines[$i] =~ m/Kernel panic/){
        my $count=5;
        do{
            push(@Kenel_panic_lines,$lines[$i]);
            $count--;
        }until($count==0);
    }
    if($lines[$i] =~ m/Exception stack/){
        my $count=10;  
        do{
            push(@Kenel_panic_lines,$lines[$i]);
            $count--;
        }until($count==0);
        print $fh_01 "@Kenel_panic_lines";
    }
}

動く必要があると思います

print $fh_01 "@Kenel_panic_lines";

if 文の外側。

プログラムの流れが見えるように、コードをインデントする必要があります

#!/usr/bin/perl
use strict;
use warnings;
open(my $fh,"<dmesg_TZ.txt") or die"can not open the file";
open(my $fh_01,">dmesg.txt") or die"can not open the file";
my @lines=<$fh>;
close($fh);

for(my $i=0;$i<=$#lines;$i++){

    my @Kenel_panic_lines;

    if($lines[$i] =~ m/Kernel panic/){
        my $count=5;
        print "5\n";
        do{
            push(@Kenel_panic_lines,$lines[$i++]);
            $count--;
        }until($count==0);
    }
    if($lines[$i] =~ m/Exception stack/){
        my $count=10;
        print "10\n";
        do{
            push(@Kenel_panic_lines,$lines[$i++]);
            $count--;
        }until($count==0);
    }
    print $fh_01 join '', @Kenel_panic_lines;

複数行の正規表現を使用します。このようなもの：

$ perl grep-A.pl 'kernel panic' 2 'exception stack' 4 <input.txt >output.txt  

$ cat output.txt
Kernel panic
kp a
kp ab
Exception stack
es two z1
es two z2
es two z3
es two z4
Kernel panic
kp two a
kp two ab
Kernel panic
kp three a
kp three ab
Exception stack
es z1
es z2
es z3
es z4
Exception stack
es three z1
es three z2
es three z3
es three z4

-

$ cat grep-A.pl
my $kw0t =            $ARGV[0];
my $kw0c = ".*?\\n" x $ARGV[1];
my $kw1t =            $ARGV[2];
my $kw1c = ".*?\\n" x $ARGV[3];

my @file;
my $ouch;
while(<STDIN>) { push (@file, $_); }
$ouch = join '', @file;

my @matches = $ouch =~ /($kw0t\n$kw0c|$kw1t\n$kw1c)/gmsi;

print @matches, "\n";

より簡単なアプローチは、例えば、

egrep -A 10 "(Exception stack|Exception stack)" dmesg_TZ.txt
