对目录中的所有文件运行，分别对待每一个，使用AWK [英] Run on all files in a directory, treating each separately, using AWK

问题描述

我想运行在一个目录下的每个文件的awk脚本，但AWK命令必须只在该文件中运行 - 也就是说，它确定的RS之间的搜索和返回什么是应该，但我需要它停止，当它到达一个文件的末尾，以及在下一文件的开头重新开始。

I want to run an AWK script on each file in a directory, but the AWK command must run only within that file - that is, it searches between a defined RS and returns what it is supposed to, but I need it to stop when it reaches the end of one file, and begin again at the start of the next file.

我有这个运行的单独对每个文件如下：

I have this running which works on each file individually:

awk '!/value1|value2/ && NF {print FILENAME " - " RS,$1}' RS="value" file1 > result.txt

但输出不正确的，也就是说，使用在一个目录其应用到每个文件时

But the output isn't correct, say, when applying it to each file in a directory using

find . -type f | awk ... file1 > result.txt

我将如何得到它在每个文件单独看，但结果追加到同一个文件？我不知道很遗憾。我想这是通过将每个文件到一个变量有AWK看看那个，但我不知道该怎么做。

How would I get it to look at each file individually, but append the results into the same file? I have no idea unfortunately. I guess it's by adding each file into a variable and having AWK look at that, but I am not sure how to do it.

interface Vlan3990
 ip address 172.17.226.23 255.255.255.254

文件文件2：

version 12.2
ip tacacs source-interface Loopback99
ip vrf test
 description xx
interface Loopback99
 description Management Loopback
interface Loopback100
 shutdown

输出

find . -type f | xargs awk '!/description|shutdown/ && NF {print FILENAME " - " RS,$1}' RS="interface" | more
./file1 - interface Vlan3990
./file2 - interface version

我不知道那里的输出接口版本'从...

I am not sure where the output 'interface version' is coming from...

推荐答案

试试这个，给你2张贴输入文件：

Try this, given your 2 posted input files:

$ gawk '
    function prtName() {
        if (name)
            print FILENAME, name
        name=""
    }
    /^interface/                { prtName(); name=$0 }
    /^ (description|shutdown)/  { name="" }
    ENDFILE                     { prtName() }
' file1 file2
file1 interface Vlan3990

这就是你想要的？请注意，这是gawk的特异性（礼貌 ENDFILE ），我认为是好的，因为你张贴的样本命令也呆子，具体的，但如果这是一个问题，只需添加一个测试FNR == 1和变革ENDFILE来结束：

Is that what you're looking for? Note that it's gawk-specific (courtesy of ENDFILE) which I assume is fine since the sample command you posted is also gawk-specific but if that's an issue just add a test for FNR==1 and change ENDFILE to END:

$ awk '
    function prtName() {
        if (name)
            print filename, name
        name=""
    }
    FNR==1                      { prtName(); filename=FILENAME }
    /^interface/                { prtName(); name=$0 }
    /^ (description|shutdown)/  { name="" }
    END                         { prtName() }
' file1 file2
file1 interface Vlan3990
