批处理-从变量中提取特定单词 [英] Batch - extract specific word from a variable

问题描述

我正在寻找使用DOS命令/脚本从段落中提取特定单词的方法.我正在将文本设置为变量.

I am looking to extract a specific word from a paragraph using DOS commands/script. I am setting the text to a variable.

set "Status=matched: 15:19:39 03/15/2016    from=10.18.20.116   oid=.1.3.6.1.4.1.1302.3.12.10.2.0.2 trap= n/a   specific= n/a   traptime=2822 hours 58 minutes 52 seconds   community=NOM   agent=10.18.20.116  version=v2c var1=1016273298 var2=.1.3.6.1.4.1.1302.3.12.10.2.0.2    var3=vmsitescope01  var4=1470979 Active Job Completed with Exit Status 58   var5=Alert Raised on: March 15, 2016 3:19 PM Job: 2726538 Tree Type : Server  Tree Name : ALL MASTER SERVERS Nodes : fmsnbu700 Job Policy: FMS7-DD-Linux-ALL_LOCAL_DRIVES Exit Status: 58 (can't connect to client) Client: ipreavpada01nb New State: Done Alert Policy: Client Job Completion Status OpsCenter Server: FMSOPSCENTER01 Comment:     var6=Client Job Completion Status   var7=   var8=   var9=FMSOPSCENTER01"

我正在尝试提取FMSOPSCENTER01的var9值.

i am trying to extract var9 value which is FMSOPSCENTER01.

我试图在for语句中使用'='作为分隔符，并提取第二个值进行测试.

I am trying to use '=' as a delimiter in a for statement and extracting second value for testing.

for /F "delims==" %G in ('%status%') DO (set "State=%H")

但是它抛出客户:这是意外的."

But its throwing a "Client: was unexpected at this time."

我们将不胜感激.

推荐答案

@echo off
setlocal EnableDelayedExpansion

set "Status=matched: 15:19:39 03/15/2016    from=10.18.20.116   oid=.1.3.6.1.4.1.1302.3.12.10.2.0.2 trap= n/a   specific= n/a   traptime=2822 hours 58 minutes 52 seconds   community=NOM   agent=10.18.20.116  version=v2c var1=1016273298 var2=.1.3.6.1.4.1.1302.3.12.10.2.0.2    var3=vmsitescope01  var4=1470979 Active Job Completed with Exit Status 58   var5=Alert Raised on: March 15, 2016 3:19 PM Job: 2726538 Tree Type : Server  Tree Name : ALL MASTER SERVERS Nodes : fmsnbu700 Job Policy: FMS7-DD-Linux-ALL_LOCAL_DRIVES Exit Status: 58 (can't connect to client) Client: ipreavpada01nb New State: Done Alert Policy: Client Job Completion Status OpsCenter Server: FMSOPSCENTER01 Comment:     var6=Client Job Completion Status   var7=   var8=   var9=FMSOPSCENTER01"

for %%a in (!Status!) do (
   if "!var!" equ "var9" (
      set "var9=%%a"
      goto break
   ) else (
      set "var=%%a"
   )
)
:break
echo var9 = %var9%

在此方法中，普通的 for 命令用于按空格或等号(或逗号或分号，即FOR命令的值集中的默认定界符)分隔Status变量中的所有标记.;然后，只需将令牌放在"var9"之后即可.

In this method a plain for command is used to separate all tokens in Status variable by space or equal-sign (or comma or semicolon, the default delimiters in the set of values of FOR command); then, just take the token after the "var9" one.

编辑2018/04/27 :添加了新方法

下面的新方法允许获取所有 var#变量的值:

The new method below allows to get the value of all var# variables:

@echo off
setlocal EnableDelayedExpansion

set "Status=matched: 15:19:39 03/15/2016    from=10.18.20.116   oid=.1.3.6.1.4.1.1302.3.12.10.2.0.2 trap= n/a   specific= n/a   traptime=2822 hours 58 minutes 52 seconds   community=NOM   agent=10.18.20.116  version=v2c var1=1016273298 var2=.1.3.6.1.4.1.1302.3.12.10.2.0.2    var3=vmsitescope01  var4=1470979 Active Job Completed with Exit Status 58   var5=Alert Raised on: March 15, 2016 3:19 PM Job: 2726538 Tree Type : Server  Tree Name : ALL MASTER SERVERS Nodes : fmsnbu700 Job Policy: FMS7-DD-Linux-ALL_LOCAL_DRIVES Exit Status: 58 (can't connect to client) Client: ipreavpada01nb New State: Done Alert Policy: Client Job Completion Status OpsCenter Server: FMSOPSCENTER01 Comment:     var6=Client Job Completion Status   var7=   var8=   var9=FMSOPSCENTER01"

set "Status=%Status: var=" & set "var%"

echo var5="%var5%"
echo var9="%var9%"
