Good day,

I would like to shorten the following test.txt file by batch and only transfer certain columns to a new testnew.txt.

test.txt:

1;2;3;4;5;

testnew.txt:

1;3;5;

I know I can do this using the following batch code:

FOR / F "tokens = 1,2,3,4,5 delims =;" %%a in ("% source%") do echo %%a;%%c;%%e;

But how can I save it in my target file now?

Use redirection, either `1>` or `1>>`. – Compo May 25 '20 at 15:00
Like @Compo said, just add `>> filename.txt` to the end of the echo. `>>` redirects output and appends it to a new line of the file whilst `>` creates a new file and overrides files with the name – Nico Nekoru May 25 '20 at 17:31

like so: FOR / F "tokens = 1,2,3,4,5 delims =;" %%a in ("%source%") do echo %%a;%%c;%%e; >>%target% – Julius May 25 '20 at 19:40
Check `for /?` for the correct syntax. Don't try to guess it. – Stephan May 26 '20 at 19:15
