linux – 在bash脚本中使用引号和空格的awk

导读：我在接收到的snmp陷阱中的bash变量集中输出以下内容： echo $var Nov 27 16:20:34 witness logger: trap: vars: DISMAN-EVENT-MIB::sysUpTimeInstance = 0:6:10:29.06,SNMPv2-MIB::snmpTrapOID.0 = SNMPv2-SMI::enterprises.11.2.29.2.90.0.10000002,SNMPv2

我在接收到的snmp陷阱中的bash变量集中输出以下内容：

echo $var

Nov 27 16:20:34 witness logger: trap: vars: DISMAN-EVENT-MIB::sysUpTimeInstance = 0:6:10:29.06,SNMPv2-MIB::snmpTrapOID.0 = SNMPv2-SMI::enterprises.11.2.29.2.90.0.10000002,SNMPv2 SMI::enterprises.11.2.29.2.90.1 = "Finished Number",SNMPv2-SMI::enterprises.11.2.29.2.90.2 = "Filter Cirteria: [called='3333']",SNMPv2-SMI::enterprises.11.2.29.2.90.3 = "Cleared",SNMPv2     SMI::enterprises.11.2.29.2.90.4 = "major Over-Flow alert on Finished Number for ['3333']",SNMPv2 SMI::enterprises.11.2.29.2.90.5 = "The Corresponding Metric Value is: 0.5",SNMPv2- SMI::enterprises.11.2.29.2.90.6 = "Over-Flow",SNMPv2-SMI::enterprises.11.2.29.2.90.7 = "Tue Nov 27 16:20:05 CET 2012"

我试图在变量中获得以下输出：

var1 = "Tue Nov 27 16:20:05 CET 2012"
var2 = "Finished Number"
var3 = "The Corresponding Metric Value is: 0.5"
var4 = "Cleared"
var5 = "major Over-Flow alert on Finished Number for ['3333']"

我想通过awk这样做

基于snmp OID：enterprises.11.2.29.2.90.4,enterprises.11.2.29.2.90.5,11.2.29.2.90.6等…

但似乎无法仅提取引用内容的内容“”

解决方法

看起来你想要匹配双引号内的所有字符串,这是用grep最简单的方法：

$echo $var | grep -o '"[^"]*"'

"Finished Number"
"Filter Cirteria: [called=3333]"
"Cleared"
"major Over-Flow alert on Finished Number for [3333]"
"The Corresponding Metric Value is: 0.5"
"Over-Flow"
"Tue Nov 27 16:20:05 CET 2012"

说明：

-o只??打印匹配行的部分.

"     # Match opening double quote
[^"]* # Match anything not a double quote
"     # Match closing double quote

希望这有助于您入门.
