I want to check this "tockeck.pgn":

If I typ this in the command prompt:

Code: Select all

pgn-extract -nosetup tocheck.pgn -nothers.pgn > nosetup.pgn

Two output pgn files are created "nosetup.pgn" & "others.pgn"

But the two games are in the "nosetup.pgn" output
And the "others.pgn" output database is emty.

Do I do something wrong or is this a bug in pgn-extract?

The command is -nosetuptags, at least on my computer.

[Jonathan003]

Thanks abulmo2

If I type this:

Code: Select all

pgn-extract -nosetuptags tocheck.pgn -nsetup.pgn > nosetup.pgn

Two output pgn files are created nosetup.pgn containing the two games
And setup.pgn which is empty.

So something still goes wrong

Try --nosetuptags (long options are given with 2 dashes). I use it all the time, and works for me on linux.

pgn-extract --nosetuptags input.pgn -o nosu.pgn -n su.pgn

[Jonathan003]

Thanks chesscobra.

This also works:
pgn-extract --nosetuptags tocheck.pgn -nsetup.pgn > nosetup.pgn
or this
pgn-extract --nosetuptags tocheck.pgn -onosetup.pgn -nsetup.pgn


It is strange that I don't get an error message, but a wrong ouput if I type:
pgn-extract -nosetuptags tocheck.pgn -nsetup.pgn > nosetup.pgn

[chesskobra]

I think there is no error in the way you called. When you pass -nosetuptag (with 1 dash), it is treated as the -n option with file name osetuptag. Then later when you pass -n other.pgn, it overrides -n osetuptag. But since --nosetuptags is not passed and no other filter is passed, it matches all games, and other.pgn is empty. If you passed -n other.pgn -nosetuptag, then you would get osetuptag as the empty file. I have not tested and haven't looked at the code, but most likely this is what is happening.
