1 .txt file contains abc 1234 def 2.txt file contains efg ? How can I replace the ? in 2.txt with the 1234 from 1.txt so that 2.txt becomes efg 1234 The 1234 here is a variable.. I hope everyone can solve this difficult problem that has bothered me for more than half a year. I'd be extremely grateful.

Actually, although the OP described the problem clearly, the conditions given are a bit too few. Just doing what you described in the post above is not hard, but it depends on what the contents of your 1.txt and 2.txt are. @echo off&setlocal for /f "tokens=*" %%a in (1.txt) do set aa=%%a <nul set/p= %aa:~10,4%>>2.txt The problem in the post above can be solved like this. I don't think the contents of your 1.txt and 2.txt are only this little, right???

There are many ways to do it. You can take the 1234 in 1.txt as a parameter for call to implement it.

Here I will only deal with the text format you gave: 1234 is a variable, the length of the variable can change, and the number of spaces before and after the variable can also change @echo off sed "1s/abc\(.\)def/\1/" 1.txt> temp1.txt sed "/?/r temp1.txt" 2.txt\|sed "1N;s/?.\n\(.\)/\1/"> temp2.txt del temp1.txt type temp2.txt pause [ Last edited by amao on 2007-2-3 at 02:33 AM* ]
