如何比较两个文件并将第二个文件中的所有行打印到输出文件bash脚本

我正在尝试获得以下输出。我有 2 个输入文件，我们只需要两个输入文件中的通用 :names 以及它们下面的行 .name/of/file 行。

到目前为止我已经尝试过：

awk 'FNR==NR { a[$1]; next }NF<=1{ flag=0 }$1 in a { print; flag=1; delete a[$1]; next }flag{ printf "%s\n",$0 }' file1 file2

输出：

:name1
    ./name/of/file [logfile] [ error in file coming since Day : 1 ]
    ./name/of/file [logfile] [ error in file coming since Day : 1 ]
:name3
    ./name/of/file [logfile] [ error in file coming since Day : 24 ]
    ./name/of/file [logfile] [ error in file coming since Day : 24 ]
:name4
    ./name/of/file [logfile] [ error in file coming since Day : 3 ]
    ./name/of/file [logfile] [ error in file coming since Day : 3 ]
    ./name/of/file [logfile] [ error in file coming since Day : 3 ]
    ./name/of/file [logfile] [ error in file coming since Day : 3 ]

输入文件1：

:name1
./name/of/file [logfile] [ error in file coming since Day : 1 ]
./name/of/file [logfile] [ error in file coming since Day : 1 ]

:name2
./name/of/file [logfile] [ error in file coming since Day : 1 ]

:name3
./name/of/file [logfile] [ error in file coming since Day : 24 ]
./name/of/file [logfile] [ error in file coming since Day : 24 ]

 :name1
./name/of/file [logfile] [ error in file coming since Day : 40]
./name/of/file [logfile] [ error in file coming since Day : 40 ]

:name4
./name/of/file [logfile] [ error in file coming since Day : 3 ]
./name/of/file [logfile] [ error in file coming since Day : 3 ]
./name/of/file [logfile] [ error in file coming since Day : 3 ]
./name/of/file [logfile] [ error in file coming since Day : 3 ]

:name5
./name/of/file [logfile] [ error in file coming since Day : 6 ]
./name/of/file [logfile] [ error in file coming since Day : 6 ]

:name4
./name/of/file [logfile] [ error in file coming since Day : 10 ]
./name/of/file [logfile] [ error in file coming since Day : 10 ]
./name/of/file [logfile] [ error in file coming since Day : 10 ]
./name/of/file [logfile] [ error in file coming since Day : 10 ]

输入文件2：

:name1 ABC123 12345
:name3 EFG789 67898
:name4 HIJ547 01234

所需的输出文件:

:name1 ABC123 12345
    ./name/of/file [logfile] [ error in file coming since Day : 1 ]
    ./name/of/file [logfile] [ error in file coming since Day : 1 ]
:name3 EFG789 67898
    ./name/of/file [logfile] [ error in file coming since Day : 24 ]
    ./name/of/file [logfile] [ error in file coming since Day : 24 ]
:name4 HIJ547 01234
    ./name/of/file [logfile] [ error in file coming since Day : 3 ]
    ./name/of/file [logfile] [ error in file coming since Day : 3 ]
    ./name/of/file [logfile] [ error in file coming since Day : 3 ]
    ./name/of/file [logfile] [ error in file coming since Day : 3 ]

  1. 您的命令中有一个拼写错误：file1并且file2应该被交换。
  2. 第一个字段作为索引保存在数组中a，但其余行（或$2和$3）作为​​值丢失。该值需要稍后打印。
  3. 缺少四个缩进空间来匹配您的预期输出。

老的：

awk '
    FNR==NR { a[$1]; next }
    NF<=1{ flag=0 }
    $1 in a { print; flag=1; delete a[$1]; next }
    flag{ printf "%s\n",$0 }
' file1 file2

新的：

awk '
    FNR==NR { k=$1; $1=""; a[k]=$0; next }
    NF<=1{ flag=0 }
    $1 in a { print $0 a[$1]; flag=1; delete a[$1]; next }
    flag{ print "    " $0 }
' file2 file1
