我该怎么办？

bridge-domain AAAA
mac
aging
time 3
!
limit
maximum 12
notification both
!
port-down flush disable
!
igmp snooping profile igmp-snoop  <---

在此行之后，我需要从另一个文本文件中添加一行行，如下所示：

interface Bundle-Ether AAAAA
igmp snooping profile igmp-snoop
dhcp ipv4 snoop profile
static-mac-address 0001
static-mac-address 0002
!

所以基本上我需要从text2.txt中每6行读取一次，并将每12行追加到text1.txt中

期望的输出：

bridge-domain AAAA
mac
aging
time 3
!
limit
maximum 12
notification both
!
port-down flush disable
!
igmp snooping profile igmp-snoop
interface Bundle-Ether AAAAA
igmp snooping profile igmp-snoop
dhcp ipv4 snoop profile
static-mac-address 0001
static-mac-address 0002
!
bridge-domain BBBB
mac
aging
time 3
!
limit
maximum 12
notification both
!
port-down flush disable
!
igmp snooping profile igmp-snoop
interface Bundle-Ether BBBB
igmp snooping profile igmp-snoop
dhcp ipv4 snoop profile
static-mac-address 0001
static-mac-address 0002
!

等...直到文件结尾。

Answer 1

这可能对您有用（GNU sed）：

sed -e '12~12{:a;R file2' -e 'x;s/^/x/;/x\{6\}/!{x;ba};z;x}' file1

这将从file2依次读取file1中每12行六行。它在保留空间中使用一个计数器，该计数器在第六行之后重置。

Answer 2

awk '
    NR==FNR {
        rec = rec $0 ORS
        if ( (FNR % 6) == 0 ) {
            recs[FNR/6] = rec
            rec = ""
        }
        next
    }
    { print }
    (FNR % 12) == 0 ) { printf "%s", recs[FNR/12] }
' file2 file1

或者如果您希望简短而隐秘（因为您要求的解决方案不是简单的s / old / new），就可以这样做：

awk 'NR==FNR{r=r$0"\n";if(!FNR%6){s[++x]=r;r="";next}!(FNR%12){$0=$0 s[++y]}1' file2 file1

以上内容可在每个UNIX盒的任何shell中使用任何awk进行工作。

这是一个awk脚本，其中包含更多的测试示例。

input.2.txt

interface Bundle-Ether AAAAA

dhcp ipv4 snoop profile

static-mac-address 0002

igmp snooping profile igmp-snoop
interface Bundle-Ether BBBB
dhcp ipv4 snoop profile

igmp snooping profile igmp-snoop
interface Bundle-Ether CCCC
dhcp ipv4 snoop profile
static-mac-address 0001
static-mac-address 0002
! CCCC section end

script.awk

FNR == NR {    # read insertion paragraph from file 1
    inpSectn = inpSectn $0; # accumlate input lines in inpSectn
    if (NR % 6 == 0) {  # if 6th line add section to array
        sectnArr[++arrCount] = inpSectn; # add inpSectn to ordered array
        inpSectn = "";  # reset inpSectn
    }
    next;      # skip further processing till all file 1 is consumed.
}
1              # output current input line.
FNR % 12 == 0 {   # every 12th line in file 2
    print sectnArr[++arrIdx]; # output section
}

运行：

awk -f script.awk input.2.txt input.1.txt

输出：

文本处理-两个文本文件：从一个文件中读取程序行，并将其追加到另一个文本文件中的字符串之后
