这次我从我的question 40066030接受的答案中搜索第二个awk-oneliner的扩展版本,所以请先看一下,谢谢。
这个awk必须被扩展,所以我可以删除包含单词foobar的所有行来自相同的块号(num),然后将insert.txt文件插入其中:
/usr/bin/awk -v num=2 'NR==FNR{ins=ins?ins ORS $0:$0; next} /<\/VirtualHost>/ && ++c==num{print ins} 1' inserted.txt vhosts-ssl.conf
以前awk的输出:
$ cat vhosts-ssl.conf
<VirtualHost *:443>
vhost 1
foobar 1
foobar 2
barfoo 1
barfoo 2
</VirtualHost>
<VirtualHost *:443>
vhost 2
foobar 2
barfoo 1
foobar 1
barfoo 2
inserted line 1
inserted line 2
</VirtualHost>
<VirtualHost *:443>
vhost 3
foobar 1
barfoo 1
foobar 2
barfoo 2
</VirtualHost>
<VirtualHost *:443>
vhost 4
foobar 1
foobar 2
barfoo 1
barfoo 2
</VirtualHost>
输出我需要得到:
$ cat vhosts-ssl.conf
<VirtualHost *:443>
vhost 1
foobar 1
foobar 2
barfoo 1
barfoo 2
</VirtualHost>
<VirtualHost *:443>
vhost 2
barfoo 1
barfoo 2
inserted line 1
inserted line 2
</VirtualHost>
<VirtualHost *:443>
vhost 3
foobar 1
barfoo 1
foobar 2
barfoo 2
</VirtualHost>
<VirtualHost *:443>
vhost 4
foobar 1
foobar 2
barfoo 1
barfoo 2
</VirtualHost>
原始输入数据供参考:
$ cat inserted.txt
inserted line 1
inserted line 2
$ cat vhosts-ssl.conf
<VirtualHost *:443>
vhost 1
foobar 1
foobar 2
barfoo 1
barfoo 2
</VirtualHost>
<VirtualHost *:443>
vhost 2
foobar 2
barfoo 1
foobar 1
barfoo 2
</VirtualHost>
<VirtualHost *:443>
vhost 3
foobar 1
barfoo 1
foobar 2
barfoo 2
</VirtualHost>
<VirtualHost *:443>
vhost 4
foobar 1
foobar 2
barfoo 1
barfoo 2
</VirtualHost>
我试图在打印之前插入各种搜索和替换以及删除片段,但这不起作用(愚蠢的我):(类似的东西:
/usr/bin/awk -v num=2 'NR==FNR{ins=ins?ins ORS $0:$0; next} /<\/VirtualHost>/ && ++c==num{!/foobar/ print ins} 1' inserted.txt vhosts-ssl.conf
提前致谢。
答案 0 :(得分:1)
您必须稍微修改脚本
$ awk -v num=2 'NR==FNR{ins=ins?ins ORS $0:$0; next}
/<VirtualHost/&&++c==num{p=1}
p&&/<\/VirtualHost>/{print ins; p=0}
!p||!/foobar/' insert.file orig.file
