获取在Bat文件中运行的exe的进程ID

这将启动一个可执行文件并获取PID：

 @echo off for /f "tokens=2 delims==; " %%a in (' wmic process call create "notepad.exe" ^| find "ProcessId" ') do set PID=%%a echo "%PID%" pause 

使用tasklist

 for /f "tokens=2" %%a in ('tasklist^|find /i "Las2xyz"') do (set pid=%%a) 

扩展foxidrive的答案显示OP的呼吁，需要参数：

 set "exe=las2xyz.exe" set "arg1=[ flightpath 2 out 5 lasformat 1 target 0 FIXCLASS 1 step 20 unit *METRIC* fov 20.0 rollfix 1 sn_number *H68_038-003* lsystem *LIDAR_1* DESTSYS 144 minele -100.00 maxele 6000.00 hoff 0.00 eoff 0.00 noff 0.00 bootnr 13110201 leg 1]" set "arg2=C:\Users\Developer-One\Desktop\las2xyz_Data\131102_003243_GPE.sdc" set "arg3=\\192.168.0.102\agis\Macquarie_Barwon_1310\Area_01\sbet_038_13110201.out" set "arg4=131102_003243_cov" for /f "tokens=2 delims==; " %%A in ( 'wmic process call create '"%exe%" "%arg1%" ^, "%arg2%" "%arg3%" - "%arg4%"' ^| find "ProcessId"' ) do set "PID=%%A" echo "%PID%" 

引用参数的内容几乎可以包含除双引号或逗号以外的任何内容。 如果在参数之间使用逗号，那么它必须被转义。

可能有另一种语法允许在参数中使用逗号，但是在参数内不允许使用括号。

那么如果你的命令行不能通过WMIC PROCESS CALL CREATE来传递，怎么办？

有一个解决方案。 但它不漂亮;-)我第一次在使用wmic的时候在转义字符串上发布这个
