Question

我希望使用DOS命令/脚本从段落中提取特定单词。我正在将文本设置为变量。

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var9值，即FMSOPSCENTER01。

我正在尝试使用'='作为for语句中的分隔符并提取第二个值进行测试。

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

但它抛出一个“客户：此时出乎意料。”

一些帮助将不胜感激。

Answer 1

@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，使用普通for命令通过空格或等号（或逗号或分号，FOR命令的值集合中的默认分隔符）分隔Status变量中的所有标记;然后，只需在＆＃34; var9＆＃34;之后取得令牌。之一。

编辑2018/04/27 ：添加新方法

下面的新方法允许获取所有var#变量的值：

@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%"

Answer 2

我建议另一种方法：

not null

Answer 3

@ECHO OFF
SETLOCAL
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 "var9=%status:"=%"
set "var9=%status:&=%"
set "var9=%var9:* var9=%"
set "var9=%var9:~1%"
IF "%var9: =%" neq "%var9%" (
 REM need to remove space and eveything after
 FOR /L %%a IN (1,1,25) DO IF "!var9:~%%a,1!"==" " SET "var9=!var9:~0,%%a!"&GOTO done
)
:done
ECHO "%var9%"

set "var9=%status:"=%"
SET "var9="%var9: =" "%""
FOR %%a IN (%var9%) DO (
 SET "varx=%%~a"
 IF "!varx:~0,5!"=="var9=" SET "var9=!varx:~5!"&GOTO done2
)
:done2
ECHO "%var9%"

第一个set会移除status的引号，并将结果分配给var9。

然后从&删除var9。

下一个set更改“任意字符 空间 var9”到没有

下一个set删除=（假设第一个“ Space var9”是关键字符串）

接下来，我们测试“var9 = xxx”后面是否有任何内容。如果是这样，那么寻找空间，抓住子串并强制终止循环。我假设要重试的字符串长度<25个字符。

然后还有第二个例程就足够了。

第一个set会移除status的引号，并将结果分配给var9。

下一个set更改'空间'到'“空间”'并在结果的每一端放置引号。结果是字符串变成了一系列带引号的字符串。

接下来，依次处理每个引用的字符串。如果前5个字符是'var9 ='，则删除前5个字符并终止循环。

请注意，此解决方案需要delayedexpansion，并且可能会对某些符号表现出敏感度。

Answer 4

是的，我知道这个问题既老又已经回答了。这是另一种方法。字符串中的撇号必须与另一个撇号一起逃脱。对于来自文件或其他流的数据，这不应该是一个问题。

@ECHO OFF
