windows - Batch Delete a line in a text file? -


I am pulling my hair by finding a simple example of a dose batch file which removes the first line of several thousand txt Save files with files and original file names. After a batch process by another program, I have to add the removed line (a text string that includes "X, Y, Z") at the beginning of each file after external processing.

You use more + 1 to leave the first line of the file can do. You can then pipe it temporarily (you can not edit the text file in the place):

  for% (* .txt) in% x (plus + 1% X "& gt; tmp   

You can then use the same technique to add the first line again:

 % for% (* .txt) in x (* .xx, x, y, z and type "% x")> tmp and move / u tmp "% x")   

Use them in a batch file, % signals two Get here:

  @echo off for %% x (* .txt) (for more + "%% x in (* .txt) Run your utility here (Exo, Y, Jade, gt; Tmp type "% x" & gt; X% is OK, apparently  more  does not work with very large files, which makes me wonder I & rsquo; tmp Move / y tmp "%% x")   

Alternatively, if your file does not have empty rows, then it should work (though it resembles CSV from me collected) :

 For the % x x (* .txt) (*. / F "skip = 1 delims =" %% l in ("%% x") ((; gt; & gt; TMP resonance. %% l) / y tmp "%% x")
