@echo off&setlocal ENABLEDELAYEDEXPANSION set a=abcdefghijklmnopqrstuvwxyz set /a a_=(%random%+26)%%26 set /a b_=(%random%+26)%%26 set /a c_=(%random%+26)%%26 set /a d_=(%random%+26)%%26 set /a f_=(%random%+26)%%26 set /a g_=(%random%+26)%%26 set h=!a:~%a_%,1!!a:~%b_%,1!!a:~%c_%,1!!a:~%d_%,1!!a:~%f_%,1!!a:~%g_%,1! set j=!a:~%a_%,1!!a:~%b_%,1!!a:~%c_%,1!!a:~%d_%,1!!a:~%f_%,1! set i=!a:~%a_%,1!!a:~%b_%,1!!a:~%c_%,1!!a:~%d_%,1! set k=!a:~%a_%,1!!a:~%b_%,1!!a:~%c_%,1! 想随机获取%h% %j% %i% %k%这4个中的一个,如果能把位数变成随机的更好~~

搜索得到答案: set var1=%h% %j% %i% %k% set/a var2=%random%%%4+1 for /f "tokens=%var2% delims= " %%x in ("%var1%") do ( echo %%x) pause 不知道有没更精简的不~ : )

是这个意识吗？

@echo off&Setlocal EnableDelayedExpansion
set "str=abcdefghijklmnopqrstuvwxyz"
set /a n=!random!%%26
echo !str:~%n%,1!
pause

要随机位数+随机字符的字符串运行一次,得到一行,如: yry gdtukk rsjkjo fyoihi dfswestyui 应该也得限制长度吧,不然估计会死机...

作者: moniuming 时间: 2008-12-3 22:16 标题: 这样?

@echo off&Setlocal Enabledelayedexpansion
set "str=abcdefghijklmnopqrstuvwxyz"
for /l %%a in (1 1 20) do (
  set /a "var1=!random!%%10+5","n=0"&set "var="
  call :lb
)
echo.&pause&goto :eof
:lb
if "%n%"=="%var1%" (echo %var%&goto :eof)
set /a n+=1,var2=%random%%%26
set "var=%var%!str:~%var2%,1!"
goto :lb

是的,一行就够了,有点深度,我研究下,多谢指教!!
