Hehe, didn't expect that number sorting actually caused the second storm in the union. It's lively. Also post a piece of previous code to add some fun : @echo off&goto start&rem 数字排序 Numbers are in a.txt, one per line Can sort any integer within 200 digits. (Including negative numbers, positive numbers, 0, and repeated numbers) Disadvantage: For numbers starting with 0, the leading 0 will be ignored in the result ::by 26933062 2007-11-25 :start setlocal EnableDelayedExpansion for /l %%a in (1 1 200) do set lin=0!lin! for /f %%a in (a.txt) do ( set "str=%%a" if "!str:~0,1!"=="-" (set fus=a&set str=!str:~1!&set zf=_) else set zf=+ set str=!lin!!str! set !zf!!str:~-200! !random!!random!!random!!random!!random!!random!!random!=a ) if defined fus call :sort _ /r call :sort + pause&exit :sort for /f "tokens=1,2 delims=_+= " %%a in ('set %1^\|sort %2') do ( for /f "tokens=* delims=0" %%i in ("%%a") do ( if "%1"=="_" (set fuhao=-) else set "fuhao=" if "%%i"=="" (echo !fuhao!0) else echo !fuhao!%%i ) ) goto :eof

It can range from negative numbers to positive numbers, and it will remove duplicate numbers. It cannot correctly handle numbers that start with 0. @echo off setlocal enabledelayedexpansion set str= %random% %random% -%random% %random% %random% -%random% %random% -%random% %random% %random% :: For a line - by - line number in a.txt, use the next line to read, and do not need the previous line :: The number before the previous line set str= %random%... must have a space in front ::for /f %%i in (a.txt) do set str=!str! %%i echo The array before sorting is: %str:~1% :sort set num=m for %%i in (%str%) do if %%i lss !num! set num=%%i set ret=%ret% %num% set str=!str: %num%=! if not "%str%" == "" goto sort echo The array after sorting is: %ret:~1% pause exit

Simplify the terse scheme, and we can modify it if there are deficiencies. @echo off&setlocal enabledelayedexpansion set/p str=Enter a number (separated by spaces) for %%i in (%str%) do ( set str=0000000000%%i set .!str:~-10! !random!=%%i ) for /f "tokens=2 delims==" %%i in ('set .') do set/p=%%i <nul pause>nul

So lively, I'll also add a part. The drawback is that the efficiency is a bit low... @echo off & Setlocal EnableDelayedExpansion for /L %%i in (1,1,5) do ( set skip=.!skip! findstr /rc:"^^!skip!$" file.txt\|sort ) In the for, 5 is specified according to the maximum number of digits. If you don't know, you can also write a for statement to calculate it. I omitted it here.

I didn't understand the moderator's code, can you explain it? It seems that negative number sorting is not supported

It seems that negative numbers are not supported for sorting It's simply to find numbers from 1-digit to 5-digit using findstr according to the number of digits, and then sort them with sort. But the premise is that the numbers are all positive integers and the maximum number of digits is known. Strictly speaking, this is not sorting~

Why add a long string of zeros in front of a number, and then when traversing in the environment variable, the zeros are truncated, and they can be automatically sorted? Please give your advice, great experts.

99 1 888 The sorting result is 1 888 99 If padding with zeros, the result is: 00001 00099 00888 ……

Learned from this forum for 3 days, today I finally can understand this code. In my eyes as a newbie, this way of thinking is very unique. In other people's eyes, maybe not unique, but classic.

&&Unexpectedly, a single stone stirs up thousands of waves. I haven't been to the forum for a few days, and this post has become an essence post and is so popular, which is really beyond my initial expectation. Today, I studied my original code again and have the following highly universal code: @echo off&setlocal enabledelayedexpansion set "str=101 20 14 13 19 18 16 11 5 -7" for %%i in (%str%) do call,set var=!var! n%%i for %%i in (%var%) do set a=%%i&call :lp echo !var:n=! pause>nul&goto :eof :lp for %%i in (!var!) do ( set b=%%i if !b:~1! lss %a:~1% ( set var=!var:%a% =! set var=!var:%%i=%%i %a%! ) )

@echo off&for /f "delims=" %%i in ('sort /+n c.txt') do echo %%i If comparing three-digit numbers, change the n value to 3.
