Regex awk输入文件在引号中有空格

你好

尝试学习一些AWK，将一些Juniper防火墙配置转换为Cisco或Palo配置。其中一部分是解析配置。我这里有一个样本：

set service "RDP" protocol tcp src-port 0-65535 dst-port 3389-3389 
set service "LDAPS" protocol tcp src-port 0-65535 dst-port 636-636 
set service "SOAPS" protocol tcp src-port 0-65535 dst-port 444-444 
set service "KEYS-ADMIN" protocol tcp src-port 0-65535 dst-port 9000-9000 
set service "WSUS-MDM" protocol tcp src-port 0-65535 dst-port 8530-8530 
set service "WSUS-MDM" + tcp src-port 0-65535 dst-port 8531-8531 
set service "WSUS-MDM" + tcp src-port 0-65535 dst-port 8531-8531 
set service "HTTPS-MDM" protocol tcp src-port 0-65535 dst-port 8443-8443 
set service "IPSEC - 4500" protocol udp src-port 0-65535 dst-port 4500-4500 
set service "IPSEC - 4500" + tcp src-port 0-65535 dst-port 1433-1433 
set service "IPSEC - 4500" + tcp src-port 0-65535 dst-port 1433-1433 
set service "OKFTP" protocol tcp src-port 0-65535 dst-port 2169-2169 
set service "Bomgar 8200" protocol tcp src-port 0-65535 dst-port 8200-8200 
set service "Cisco VPN" protocol tcp src-port 0-65535 dst-port 10000-10000 
set service "Cisco VPN 2" protocol tcp src-port 0-65535 dst-port 10000-10000 
set service "Cisco VPN 2" + udp src-port 0-65535 dst-port 10000-10000 
set service "Cisco VPN 2" + udp src-port 0-65535 dst-port 500-500 
set service "Cisco VPN 2" + udp src-port 0-65535 dst-port 4500-4500 
set service "Cisco VPN 2" + 50 src-port 0-65535 dst-port 0-65535 
set service "Cisco VPN 2" + udp src-port 0-65535 dst-port 10000-10000 
set service "Cisco VPN 2" + udp src-port 0-65535 dst-port 500-500 
set service "Cisco VPN 2" + udp src-port 0-65535 dst-port 4500-4500 
set service "TrendMicro8080" protocol tcp src-port 0-65535 dst-port 8080-8080 
set service "TrendMicro26980" protocol tcp src-port 0-65535 dst-port 26980-26980 
set service "TrendMicro26980" + udp src-port 0-65535 dst-port 26980-26980 
set service "PenPal Test" protocol tcp src-port 0-65535 dst-port 522-522 
set service "HTTP8080" protocol tcp src-port 0-65535 dst-port 8080-8080 
set service "HTTPS445" protocol tcp src-port 0-65535 dst-port 445-445 
set service "MOBILEIRON-TLS" protocol tcp src-port 0-65535 dst-port 9997-9997 
set service "MOBILEIRON-TLS" + tcp src-port 0-65535 dst-port 9998-9998 

我将这段代码保存到一个名为test1的文件中，并从命令行运行以下命令：

awk -F " " 'BEGIN {OFS=","} {print $3,$5,$7,$9}' test1

虽然它基本上是有效的，但是包含在“”中的空格被awk视为有效空格。输出：

"RDP",tcp,0-65535,3389-3389
"LDAPS",tcp,0-65535,636-636
"SOAPS",tcp,0-65535,444-444
"KEYS-ADMIN",tcp,0-65535,9000-9000
"WSUS-MDM",tcp,0-65535,8530-8530
"WSUS-MDM",tcp,0-65535,8531-8531
"WSUS-MDM",tcp,0-65535,8531-8531
"HTTPS-MDM",tcp,0-65535,8443-8443
"IPSEC,4500",udp,0-65535
"IPSEC,4500",tcp,0-65535
"IPSEC,4500",tcp,0-65535
"OKFTP",tcp,0-65535,2169-2169
"Bomgar,protocol,src-port,dst-port
"Cisco,protocol,src-port,dst-port
"Cisco,2",tcp,0-65535
"Cisco,2",udp,0-65535
"Cisco,2",udp,0-65535
"Cisco,2",udp,0-65535
"Cisco,2",50,0-65535
"Cisco,2",udp,0-65535
"Cisco,2",udp,0-65535
"Cisco,2",udp,0-65535

理想情况下，我希望awk忽略“”中的空格。我想我可以把它添加为正则表达式？我用“！”吗以某种方式不确定。任何帮助都将不胜感激。

实现最终结果的方法可能有很多种（甚至可能是

awk

包含在内的方法）：

另一种可能的方法是使用

sed

：

sed 's/\("[^"]*"\)* \("[^"]*"\)*/\1,\2/g' test1

…或通过管道连接到

awk

：

sed 's/\("[^"]*"\)* \("[^"]*"\)*/\1,\2/g' test1 | awk -F ',' 'BEGIN {OFS=","} {print $3,$5,$7,$9}'

输出：

"RDP",tcp,0-65535,3389-3389
"LDAPS",tcp,0-65535,636-636
"SOAPS",tcp,0-65535,444-444
"KEYS-ADMIN",tcp,0-65535,9000-9000
"WSUS-MDM",tcp,0-65535,8530-8530
"WSUS-MDM",tcp,0-65535,8531-8531
"WSUS-MDM",tcp,0-65535,8531-8531

"IPSEC - 4500",tcp,0-65535,1433-1433

"Bomgar 8200",tcp,0-65535,8200-8200

awk解决方案是在了解后发现的。

看，我需要一段时间，但我最终明白了诀窍！左侧和右侧的组隐藏了带引号的空格，ok，并且由于您附加到每个组的

*

量词，当前字段之间的空格也会更改。。。聪明。@GBOFI，事实证明我的方法比它需要的要复杂一点（我假设），但很高兴你学到了一些东西。我发布了一个更新的解决方案，专门针对awk：）
