China DOS Union

Question: how can I use a DOS batch file to get the current username of the XP system, and then replace administrator in MirrorDir.ini?
The commands I know so far are:
echo %username% display the current username
echo %username%>a.txt append the displayed result to a.txt

But how can I use a batch file to replace administrator in MirrorDir.ini with the current XP system username?

Requirement: as soon as the batch file is run, it should immediately modify MirrorDir.ini.
I don't want to use other software to do it, many thanks.

The contents of MirrorDir.ini are as follows:

LastTask=0

MainDir=C:\Documents and Settings\Administrator\Desktop
ImageDir=d:\0beifen
MainDirHistory=C:\Documents and Settings\Administrator\Desktop
ImageDirHistory=d:\0beifen
Excludes=
StartupRun=1
DeleteOthers=1

The main issue is:

StartupRun=
DeleteOthers=

In these 2 places, the 1 after them was not added.

It seems this echo command can't add the number 1 into the file?

Also, the method I'm using is a bit complicated.

Isn't there any other simpler method?

Everyone, is there no solution?

Many thanks

Or @echo off&setlocal enabledelayedexpansion for /F "delims=" %%a in (MirrorDir.ini) do set a=%%a&set "a=!a:Administrator=%username%!"&>>hanye.txt echo.!a! del /q /f MirrorDir.ini ren hanye.txt MirrorDir.ini
Or directly use third-party commands such as sed or fr, for example
fr MirrorDir.ini -fic:Administrator -t:%username%

Many thanks to the poster above.

I've already found a solution for my method.

echo [CommonSetting]>MirrorDir.ini
echo LastTask=0>>MirrorDir.ini
echo [新任务1]>>MirrorDir.ini
echo MainDir=%userprofile%\桌面>>MirrorDir.ini
echo ImageDir=d:\0beifen>>MirrorDir.ini
echo MainDirHistory=%userprofile%\桌面>>MirrorDir.ini
echo ImageDirHistory=d:\0beifen>>MirrorDir.ini
echo Excludes=>>MirrorDir.ini
echo StartupRun=1 1>>MirrorDir.ini
echo DeleteOthers=1 1>>MirrorDir.ini

echo DeleteOthers=1 1>>MirrorDir.ini
write it as
>>MirrorDir.ini echo DeleteOthers=1

Many thanks to the poster above.

I tried it.

echo DeleteOthers=1 1>>MirrorDir.ini
written as
>>MirrorDir.ini echo DeleteOthers=1

These two actually have the same effect in actual use. No need to modify it.

This is the software I ultimately want: timed backup of desktop files

1, when written as echo.%var%>>a.txt, the last character in %var% must not be a digit
2, so adding a space like echo.%var% >>a.txt solves it, but this will cause an extra space at the end of each line
3, >>a.txt echo.%var% means you don't need to worry whether the last character of %var% is a digit, and there won't be an extra space at the end of the line either
4, your echo.%var% 1>>a.txt is actually just echo.%var% >>a.txt
