@pv -r0 -d1000 进程>nul 2>nul&&shutdown -s -t 10

借助第三方工具pv.exe，每1秒钟检测一次，检测到之后提示10秒后关机。
pv.exe：http://bbs.bathome.net/thread-1864-1-1.html

当然如此，已经说明pv是第三方工具，需要下载。- -|||||||||||||

pv xx.exe 2>nul||start "" "a.exe"

pusofalse

@echo off
for /l %%a in (1 0 1) do (
     pv a.exe 2>nul||start "" "a.exe"
     pv -r0 -d1000 -x a.exe 2>nul
)
复制代码

先检测a.exe是否运行，若无，则运行a,exe。若有，继续向下执行：

pv -r0 -d1000 -x a.exe 2>nul
-d1000: 每1000ms检测一次a.exe
-x 等待程序结束: 若发现a.exe运行中，则继续循环检测，一直到a.exe被结束才执行下面的语句goto loop

Modes:
  -s       --summary   show usage for the specified MODULE
  -h,-?    --help      display this help information
Actions:
  -k       --kill      kill process
  -a       --activate  brings process main window in the foreground
  -c       --close     close (send WM_CLOSE) to the PROCESS
  -p[nihr] --priority  set priority to "Normal", "Idle", "High", "Real Time"
    [ba]               "Below Normal" and "Above Normal" only on W2K or higher
Output Options:
  -e,      --extend    show additional information if available
  -l,      --long      show command line (can also be a filter)
  -q,      --quiet     supress headers and produce a tab-separated list
  -b       --bare      show process ID only ()
Input Options:
  -f,      --force     never prompt
  -i,      --id        use process ID instead of the PROCESS name
Filters:
  -l[mask] --long      include processes with command line matching mask
  -w[mask] --window    show processes with visible windows matching mask,
                       -e includes in search also invisible windows
  -u[mask] --usage     show processes using modules that matches mask
  -t[root] --tree      display process tree starting starting from the root
Extra Information Options:
  -g       --getenv    get startup environment for the  PROCESS
  -m       --module    show modules used by specified PROCESS
Execution Options:
  -d[time] --delay     delay time in milliseconds before executing command
  -r[err]  --repeat    repeat command in a cycle, while (%ERRORLEVEL% > err)
  -n       --number    %ERRORLEVEL% = negated number of matched processes
  -x[a]    --exit      wait for the process completion (exit)
                        'a' flag waits for all processes, -d sets time-out
  -@[file_name]        read arguments from specified file or from
                       standard input after processing the command line
Arguments can contain '*' and '?' wildcards.
Use return code (%ERRORLEVEL%) in batch files:
    0 - process found (negated number of processes if -n is specified)
    1 - empty result set, 2 - programm error
Examples:
  pv myprocess.exe        get process ID for myprocess.exe.
  pv -e                   get extended list of running processes.
  pv -k sleep*            kill all processes starting with "sleep"
  pv -m -e explorer.exe   get extended information about explorer's modules
  pv -u oleaut*.dll       list of all processes that use matching dll
  pv -ph w*.exe           set priority to hight for all matching processes
  pv explorer.exe -l"*/S" looks for explorer process with /S switch
  pv -r0 -d2000 calc.exe "2>nul" checks every 2 seconds if calc.exe is running
