文本处理 - 两个文本文件：从一个文件中读取块行并将其附加到另一个文本文件中的字符串之后

Question

我需要将两个具有固定行块的文本文件合并为一个。

我该怎么做？

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

在这一行之后，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，然后每 12 行将其附加到 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...直到文件结束。

Answer 1

这可能对你有用（GNU sed）：

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

这从 file2 顺序读取 file1 中的每 12 行 6 行。它在保持空间中使用了一个计数器，该计数器在第六行之后被重置。

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，如果您更喜欢简洁和神秘（因为您要求 sed 解决方案来解决不仅仅是 s/old/new 的问题）：

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

以上内容可以在每个 UNIX 机器上的任何 shell 中使用任何 awk。

这是一个awk 脚本，其中包含更广泛的测试样本。

input.1.txt

bridge-domain AAAA
mac
aging
time 3
!
limit
maximum 12
notification both
!
port-down flush disable
! -1
igmp snooping profile igmp-snoop  1
! 1.1
bridge-domain BBBB
mac
aging
time 3
!
limit
maximum 12
notification both
port-down flush disable
! -2
igmp snooping profile igmp-snoop 2
! 2.1
bridge-domain CCC
mac
aging
time 3
!
limit
maximum 12
notification both
port-down flush disable
! -3
igmp snooping profile igmp-snoop 3
! 3.1

input.2.txt

interface Bundle-Ether AAAAA
igmp snooping profile igmp-snoop
dhcp ipv4 snoop profile
static-mac-address 0001
static-mac-address 0002
! AAAA section end
igmp snooping profile igmp-snoop
interface Bundle-Ether BBBB
dhcp ipv4 snoop profile
static-mac-address 0001
static-mac-address 0002
! BBBB section end
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：

bridge-domain AAAA
mac
aging
time 3
!
limit
maximum 12
notification both
!
port-down flush disable
! -1
igmp snooping profile igmp-snoop  1

! 3.1

Answer 4

谢谢大家！正如我所见，有很多方法可以做到这一点。我使用了 awk 脚本，但 Ed Morton 和 potong 方法也可以！ 谢谢。
