How to delete the spaces and dates at the end of each line in the final output list.txt???

----------------------------------------------------------
c:\my\ab.exe 2007.10.26
d:\cde.com 2007.1.1
c:\f.bat 2007.1.3
----------------------------------------------------------

c:\my\ab.exe
d:\cde.com
c:\f.bat

Sorry, I just found out that scoring is possible. Everyone has worked hard. I'll add more after lifting the restriction.

If the path does not contain the & symbol, it will be very easy to handle. However, if it contains it, it will be more difficult. The following demonstration code borrows from a section of code I posted the other day (click here to view), which can be compatible with other special symbols in the path except the percent sign:

@echo off

for /f "delims=" %%i in (list.txt) do call :pickup "%%i"

pause

goto :eof



:pickup

set "route=%~1"

call :antitone "%route%"

call :intercept "%str%"

call :antitone "%route%"

echo "%str%"

goto :eof



:antitone

set str=

set "var=%~1"

:loop1

if not "%var:~0,1%"=="" set "str=%str%%var:~-1%"

set "var=%var:~0,-1%"

if not "%var%"=="" goto loop1

goto :eof



:intercept

for /f "tokens=1*" %%i in (%1) do set "route=%%j"

goto :eof

After reading everyone's replies, I'm really impressed. ;)
