Thank you very much,Penpen. You've done me a great favor !

See this or this ... Antonio Thanks, but that's too slow,when I type 123456, it takes about one minute. I worte some code, but the function is not strong, it needs to enter with space, and can not rule out duplicate items. The advantage is more faster.I type “1 2 3 4 5 6”,it takes about 8 seconds. ...

Sorry, I did't have a clear description about my question,in fact, I want to use batch to list the all combination of the 6 numbers

Just enter any 6 numbers , How many different combinations can they make?
for example, I input 3numbers "1\3\2",there could be "123 132 213 231 312 321"
How about "6" numbers ,Could you help me ?

Hi.Aacini I am very interested in your question.So I wrote some code as follow But my English is not very good, so there might be some misunderstanding about your problem, please forgive me @echo off setlocal enabledelayedexpansion set /p tok=tokens=: for /f %%a in ('findstr .* test.txt^|find /v /c ...

Or,try this code




My friend told me : Alway try to avoid using “find\findstr”.

Edit your post fugitive, that method is shown by einstein1969, not me. [Offtopic] By the way, is the poem written by you fugitive? [/Offtopic] Thanks for reminding. haha……I learned from both of you “Tokens” ignore space character in front of line,and einstein 1969 's code does not need to calculate...

How about this one,The code is more complex, but not used "find". @echo off for /f "delims=" %%a in ('dir /ad /b /s target') do call :check "%%a" pause&exit /b :check set "ept=" for /f "delims=" %%b in ('dir /a /b "%~1"') do set ept=no ...
