adb-logcat: Display lines that match a regular expression.
$ adb logcat -e ${regular_expression}
try on your machine

The command "adb logcat -e ${regular_expression}" is used in Android Debug Bridge (ADB) to view the system log messages that are output by running processes and applications on an Android device. Here's an explanation of the command and its components:

  1. "adb" is the command-line tool provided by ADB, which allows communication between a computer and an Android device.

  2. "logcat" is a command within ADB used to display the device log messages.

  3. "-e" is an option or flag used to specify a regular expression. Regular expressions are patterns used to match and search for text within a larger body of text. In this case, it is used to filter and display only the log messages that match a specific pattern.

  4. "${regular_expression}" is a placeholder indicating that you should replace it with a specific regular expression. You need to define the regular expression here to filter the log messages you want to see.

For example, if you want to see log messages related to a specific application, you can replace "${regular_expression}" with the application's package name or process ID.

Overall, this command helps to filter and display specific log messages based on a regular expression pattern.
