[文本处理] 批处理怎样把指定参数后面的数字取出并赋值给变量？

@echo off&setlocal enabledelayedexpansion
set line1="run file.txt -t 6 -n 9 c:\test\1.dat"
set line2="run file.txt -n 2 -q 5 c:test\1.dat"
set line3="run file.txt -b 4 c:\test\1.dat"

for %%a in (%line1% %line2% %line3%) do (
	echo;%%a|find "-n" >nul &&call :aa "%%~a"||(echo;命令%%~a中，var=1)
)
pause&exit
:aa
set str=%~1
set str=%str:-n=#%
for /f "tokens=2 delims=#" %%a in ("%str%") do (
	for %%b in (%%a) do (
		echo;命令%~1中，var=%%b
		goto :eof
	)
)
