Edit/Solution: execute ./adb logcat in the platform-tools directory.
Original Question:
I know that there's a way to display the LogCat for an Android device/emulator in Terminal on my Mac, but I'm not sure what the command is. This is mostly due to my incompetence with UNIX commands.
Here are my previous failures:
adb logcat
adb.exe logcat
FULL_PATH_TO_PLATFORM_TOOLS/adb logcat
FULL_PATH_TO_PLATFORM_TOOLS/adb.exe logcat
Ah, just adb logcat should work. You may need to do an explicit path if the Android SDK tools directories aren't in your PATH, but that should do it.
If you have NPM, you could install module:
$ npm install -g logcat
that will provide you to start monitoring colored logcat in console and //127.0.0.1/.
$ logcat
Here is description
In Terminal Emulator:
logcat > /sdcard/logfile.txt
This will put the logcat content in /sdcard/logfile.txt (your sd card main directory) obviously.
