使用 Perl 处理文本缺失信息

大家好，我一直在使用这个脚本：

    perl -F',\s+' -lane '
   @ARGV and $h{$F[1]}=$F[0],next;

   /^Device ID:\s+(\S+)/ && $h{$a=$1} .. /^$/ || eof() and do{
      /^$/ || eof() and $_ = "SN: $h{$a}" . ( eof() ? "" : "\n" );
   };

   print;
' dispositivoss.csv dispositivos.dat>dispositivoss.dat

它使用这两个文件。

dispositivoss.csv：

serial_number,device_id,ip_address
FOC1518Z1G2, Arq_Laboratorios_EdifB, 148.000.000.248
FOC1216U136, Arquitectura_Dir, 148.000.000.252
FOC1352V3F3, Arq.245, 148.000.000.245
FDO1129Z9Z5, Barragan_3750, 148.000.000.254

dispositivos.dat：

Device ID: Arq_Laboratorios_EdifB
IP address: 148.000.000.248
Interface: FastEthernet0/48
Port ID (outgoing port): GigabitEthernet1/0/48

Device ID: SEP0c1167231895
IP address: 148.000.000.45
Interface: FastEthernet0/4
Port ID (outgoing port): Port 1

Device ID: Arquitectura_Dir
IP address: 148.000.000.252
Interface: GigabitEthernet0/2
Port ID (outgoing port): GigabitEthernet0/1

Device ID: ARQUITECTURA_01
IP address: 148.000.000.21
Interface: FastEthernet0/1
Port ID (outgoing port): FastEthernet0

Device ID: Arq.245
IP address: 148.000.000.245
Interface: FastEthernet0/42
Port ID (outgoing port): GigabitEthernet0/1

Device ID: Barragan_3750
IP address: 148.000.000.254
Interface: GigabitEthernet0/1
Port ID (outgoing port): GigabitEthernet1/0/3

一切都很顺利，但最后，脚本写SN了Port ID：

Device ID: Arq_Laboratorios_EdifB
IP address: 148.000.000.248
Interface: FastEthernet0/48
Port ID (outgoing port): GigabitEthernet1/0/48
SN: FOC1518Z1G2

Device ID: SEP0c1167231895
IP address: 148.000.000.45
Interface: FastEthernet0/4
Port ID (outgoing port): Port 1

Device ID: Arquitectura_Dir
IP address: 148.000.000.252
Interface: GigabitEthernet0/2
Port ID (outgoing port): GigabitEthernet0/1
SN: FOC1216U136

Device ID: ARQUITECTURA_01
IP address: 148.000.000.21
Interface: FastEthernet0/1
Port ID (outgoing port): FastEthernet0

Device ID: Arq.245
IP address: 148.000.000.245
Interface: FastEthernet0/42
Port ID (outgoing port): GigabitEthernet0/1
SN: FOC1352V3F3

Device ID: Barragan_3750
IP address: 148.000.000.254
Interface: GigabitEthernet0/1
SN: FDO1129Z9Z5

我该如何保留Port ID？，有时dispositivos.dat只有一个设备信息，也会发生同样的情况。

谢谢。

答案1

更改线路：

$_ = "SN: $h{$a}" . ( eof() ? "" : "\n" );

到

$_ .= (eof() ? "\n" : "") . "SN: $h{$a}" . ( eof() ? "" : "\n" );

答案2

perl -F',\s+' -l -00nae '
   @ARGV and %h = (%h, reverse(/^(.*?),\s*(.*),/mg)),next;
   /^Device ID:\s+(\S+)/ && exists $h{$a=$1} && s/$/\nSN: $h{$a}/;
   print $_, eof() ? "": "\n";
' dispositivoss.csv dispositivos.dat > dispositivoss.dat

当您一次查看一个段落的数据时。
