コマンド
- -c ログを削除
- -d ログを出力して終了
- -f <ファイル名> ファイルに保存
- -g ログバッファのサイズを表示
- -s デフォルトのフィルタ仕様を silent に設定します。
ファイルに出力
-f
- Unfortunately, the -f option to logcat appears to be only able to create files on the file system of the android device and not on the development host.
- If you wish to create a file on the device, then specify a writable location (appropriate paths will vary by device and build, but to take a current example):
adb logcat -f /mnt/sdcard/log.txt
