Compare dois arquivos e corresponda à saída

Tenho arquivos parecidos com este:

Arquivo1:

1.1.1.7 mounting of udf filesystems is disabled Fail
1.1.1.8 mounting of FAT filesystems is disabled  Fail
1.1.5 noexec option set on /tmp partition   Fail
1.1.17 noexec option set on /dev/shm partition  Fail
1.1.21 sticky bit is set on all world-writable directories  Fail
1.3.1 AIDE is installed Fail

Arquivo2:

1.1.1.7 Ensure mounting of udf filesystems is disabled
1.1.1.8 Ensure mounting of FAT filesystems is disabled
1.1.3 Ensure nodev option set on /tmp partition
1.1.4 Ensure nosuid option set on /tmp partition

Quero comparar os dois arquivos na primeira coluna e gerar a saída onde eles correspondem. Para o conteúdo acima, a saída seria:

1.1.1.7 Ensure mounting of udf filesystems is disabled
1.1.1.7 mounting of udf filesystems is disabled Fail
1.1.1.8 Ensure mounting of FAT filesystems is disabled
1.1.1.8 mounting of FAT filesystems is disabled  Fail

Como eu faria isso?

Além disso, como eu reverteria para poder mostrar aqueles que não têm correspondência? Comparando Arquivo1 com Arquivo2 e vice-versa?

Responder1

awk '
  NR == FNR {a[$1] = $0; next} 
  ($1 in a) {print; print a[$1]}
' File1 File2
1.1.1.7 Ensure mounting of udf filesystems is disabled
1.1.1.7 mounting of udf filesystems is disabled Fail
1.1.1.8 Ensure mounting of FAT filesystems is disabled
1.1.1.8 mounting of FAT filesystems is disabled  Fail

Se você quiser fazer um teste simples para entradas não correspondentes no Arquivo2

awk 'NR==FNR {a[$1]=$0; next} !($1 in a)' File1 File2
1.1.3 Ensure nodev option set on /tmp partition
1.1.4 Ensure nosuid option set on /tmp partition

e, inversamente, entradas não correspondentes no Arquivo1

awk 'NR==FNR {a[$1]=$0; next} !($1 in a)' File2 File1
1.1.5 noexec option set on /tmp partition   Fail
1.1.17 noexec option set on /dev/shm partition  Fail
1.1.21 sticky bit is set on all world-writable directories  Fail
1.3.1 AIDE is installed Fail

(o printestá implícito).

perl -lane '
        @ARGV and $h{$F[0]}=$_,next;
        print "$_\n$h{$F[0]}" if exists $h{$F[0]};
' File2 File1

1.1.1.7 mounting of udf filesystems is disabled Fail
1.1.1.7 Ensure mounting of udf filesystems is disabled
1.1.1.8 mounting of FAT filesystems is disabled  Fail
1.1.1.8 Ensure mounting of FAT filesystems is disabled
