大家好，请帮助我，我正试图得到以下输出，所以基本上我有2个输入文件，我们只需要共同的：名称从两个输入文件以及下面的行。名称/的/文件行。
到目前为止，我已经尝试过：

awk '/:name1/{flag=1} flag;/ /{flag=0}' /path/of/input/file1

输出：

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

但它只打印了第一行。

- 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 ]

: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 ]

- 输入文件2：**

:name1
:name3
:name4

- 所需输出文件**：

: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 ]

一种awk方法：

awk '
FNR==NR { a[$1]; next }
NF<=1   { flag=0   }           # clear flag if zero or one non-white-space fields is present in the current line
$1 in a { flag=1   }           # set flag if 1st field is an index in the a[] array
flag                           # if flag == 1 then print current line to stdout
' file2 file1

这将产生：

: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 ]

输出也可以缩进：

awk 'NR == FNR { for (i = 1; i <= NF; ++i) a[$i] = 1; next }
    a[$1] { $1 = $1; print }' RS= FS='\n' OFS='\n\t' file{2,1}
