adb-logcat:tldr:468f7

The command "adb logcat *:W" is used to show the logs (logcat) from an Android device connected to a computer using the Android Debug Bridge (adb).

In more detail, here's what each component of the command means:

• "adb" stands for Android Debug Bridge, a command-line tool used to communicate with an Android device from a computer.
• "logcat" is a command that displays the logs generated by system and application processes on an Android device.
• "*" is a wildcard character that represents all tags or message types.
• "W" is a log level filter. It stands for "Warning" and indicates that only logs of warning level and above will be displayed.

So, when you run the command "adb logcat *:W", it will show the log messages with a warning level and higher from all tags or message types on the connected Android device.
