Android - adb logcat without debug logs

Question

I don't want to see debug logs from adb logcat command. There are tons of debug logs from my phone and I don't want to see them.

adb logcat --help says " *:I " will output only info logs but is there any option to filter all logs except debug.

Answer 1

From the docs here, when you specify a log level filter, it will show all messages at that level and higher. The levels are specified as:

The tag of a log message is a short string indicating the system component from which the message originates (for > example, "View" for the view system).

The priority is one of the following character values, ordered from lowest to highest priority:

• V: Verbose (lowest priority)
• D: Debug
• I: Info
• W: Warning
• E: Error
• F: Fatal
• S: Silent (highest priority, on which nothing is ever printed)

...

The following filter expression displays all log messages with priority level "warning" and higher, on all tags:

adb logcat *:W 

So with this in mind, passing the filter you mentioned *:I will log everything but Verbose and Debug logs.

Unless your intention is to show Verbose as well as the other log levels, I don't think you can do that because specifying Verbose includes anything above Verbose.

If that is the case, it might be useful for you to filter on a specific tag instead of a specific log level, or some combination of both.

Answer 2

adb logcat *:I will display all logs with priority INFO and higher.

The priority is one of the following character values, ordered from lowest to highest priority:

• V — Verbose (lowest priority)
• D — Debug
• I — Info
• W — Warning
• E — Error
• F — Fatal
• S — Silent (highest priority, on which nothing is ever printed)

The above information is available in Write and View Logs with Logcat
