私は Wine を使って Windows コマンドラインプログラム (アクセス権がない) を実行します。明らかに、標準出力に何かを書いていますが、その出力をキャプチャしようとしていますが、リダイレクトできません。
stdoutまたはstderrをファイルにリダイレクトするかどうかにかかわらず、プログラム出力は依然としてコンソールに印刷され、ファイルに書き込まれません。 stderrをリダイレクトするとワイン出力は消えますが、プログラム出力はまだ画面に印刷されます。
wine program.exe > out # File is empty, program output printed on screen
wine program.exe 2> out # Wine output gets redirected to file, program output still printed on screen
両方ともリダイレクトすると、出力は画面に印刷されず、ファイルに書き込まれません。
編集する:Windowsでは動作は似ていますが、両方ともリダイレクトすると、すべてがまだ画面に印刷されます。
以下は、完全な出力を含むいくつかの例です。
$ wine program.exe
fixme:winediag:start_process Wine Staging 1.9.23 is a testing version containing experimental patches.
fixme:winediag:start_process Please mention your exact version when filing bug reports on winehq.org.
output by program.exe
fixme:msvcrt:__clean_type_info_names_internal (0x100aaa54) stub
出力をリダイレクトしようとすると、これが発生します。
$ wine program.exe > out 2>&1
$ cat out
fixme:winediag:start_process Wine Staging 1.9.23 is a testing version containing experimental patches.
fixme:winediag:start_process Please mention your exact version when filing bug reports on winehq.org.
fixme:msvcrt:__clean_type_info_names_internal (0x100aaa54) stub
つまり、プログラムのコンソール出力が完全に失われます。プログラムはまだうまく機能し、期待どおりにいくつかのファイルを作成します。確認次元でpngcrushで同じことを行い、期待した結果を得ました。リダイレクトなし:
$ wine pngcrush_1_8_10_w32.exe test.png out.png

他のプログラムが機能しないのはなぜですか?
