text and file utility in windows

I need to do things like: taking the first x lines of text file and save it int开发者_JAVA百科o another text file, what kind of text utilities can I use in windows?

Use a decent text editor like Notepad++ or Vim.

If you aren't afraid of using the command line, I'd suggest taking a look at Gnuwin32, which is a port of many useful *nix utilities for Windows.

It contains heavyweight such as Sed, Awk, Grep etc., which are more than suited for any kind of text surgery.

if you want to write a batchfiles that extracts the first 10 lines of file myInputFile.txt to myOutputFile.txt use

  head.exe --lines=10 myInputFile.txt > myOutputFile.txt

head.exe is one of severeal GnuUtilities for MsWindows.
