bat脚本中命令执行的结果赋值给变量

bat脚本中命令执行的结果赋值给变量

rem 查找ip地址举例

for /f "delims=" %%i in ( 'ipconfig /all^| find /i "ipv4" ') do set MYIP=%%i & echo %MYIP%

rem result.txt的文件内容：

rem [INFO] APP DEMO ................................. SUCCESS [  1.111 s]
rem [INFO] APP THIRD ................................ FAILED [  1.222 s]
rem [INFO] MY WEB ................................... SKIPPED [  1.313 s]

rem 查找命令：在文件内容中查找字符串 ".... FAIL " 或者 ".... SKIP " 或者 ".... ERR "，查找结果输出到tmp.txt

set MYFILE="%CD%\result.txt"

findstr "\.\.\.\.\ FAIL \.\.\.\.\ SKIP \.\.\.\.\ ERR " %MYFILE%  >  tmp.txt

rem 查找结果写文件以后，再处理文件中的结果

for /f "tokens=* delims=" %%i in (tmp.txt) do echo %%i

for /f "tokens=* delims=" %%1 in (tmp.txt) do echo %%1

for /f "tokens=1,2 delims=...." %%a in (tmp.txt) do echo %%a %%b

for /f "tokens=1,2,3 delims=...." %%1 in (tmp.txt) do echo %%2 %%3

for /f "tokens=1-3 delims=...." %%1 in (tmp.txt) do echo %%2 %%3

for /f "tokens=* delims=...." %%1 in (tmp.txt) do echo %%1

rem 也可以直接将bat命令执行的结果字符串赋值给变量，省去了中间的写文件和读文件处理的过程

for /f "tokens=1-2 delims=...." %%1 in ( 'findstr "\.\.\.\.\ FAIL \.\.\.\.\ SKIP " %MYFILE% ' ) do (set STATUS=%%2 & echo %%1 , %%2 & echo ======)

rem IF "%STATUS%" EQU "" echo " 查找失败结果为空，未找到失败信息"

IF "%STATUS%" EQU ""  (

  echo " 无失败信息，继续处理"

) else (

  echo "有失败信息，跳到结束"

 GOTO END

)

echo ##########

echo -------- %STATUS%

echo -------- %MYIP%

:END

set MYIP=

set STATUS=

set MYFILE=
