I wanted to sort numbers in a text file and write the same in another text file for the same I am using the command given below but I am not able to get the output can someone please help me with the same
sort -n test.txt /o output.txt
There is an error message coming up for this as Input file specified two times.
(nice exercise :) )
@echo off
setlocal enabledelayedexpansion
REM convert all numbers to the same lenght by adding leading spaces:
(for /f %%i in (input.txt) do (
REM 12 leading spaces:
set "Z= %%i"
REM take last 12 digits:
echo !Z:~-12!
))>temp.txt
REM sort it:'
sort temp.txt /O temp.txt
REM remove the spaces:
(for /f %%i in (temp.txt) do echo/%%i)>output.txt
del temp.txt
For sure (nice exercise :) ) !!!
Sort numbers in text file using command prompt but not using sort command!!**

delims^=:^ tokens^=^2 you can just do "tokens=2 delims=:" (much easier to read). And you don't need commas if you use findstr /x (or maybe findstr "\<%%L\>" to be safe from stray spaces)
"tokens=2 delims=: " then. I don't know, if find is faster than findstr, but if it is, the generation of _file_.tmp surely negates the advantage.
-nsupposed to be?sortdoes not have such a parameter (seesort /?) If you use another implementation ofsort, please specify.
