logcat:tldr:2759d

The command "logcat --regex ${regular_expression}" is used to filter logcat output on an Android device based on a regular expression.

Here's a breakdown of the command:

• "logcat" is a command-line tool in Android that displays log messages from the device's system and applications. It is primarily used for debugging purposes.
• "--regex" is an option that tells logcat to use a regular expression for filtering the log messages.
• "${regular_expression}" is a placeholder for the actual regular expression. You should replace it with the specific regular expression you want to use for filtering. Note that regular expressions are a powerful tool for pattern matching and can help you search for specific log messages that match a particular pattern or condition.

For example, if you want to filter logcat output to display only log messages related to a specific tag (e.g., "MyApp"), you can use the following command: logcat --regex ".MyApp."

This command will display all log messages containing the tag "MyApp" in the output. The ".*" before and after the tag represent any characters appearing zero or more times, allowing for flexibility in the log message structure.
