Android - adb logcat without debug logs

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.

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.

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

To enable logging on some Huawei devices:

• Dial *#*#2846579#*#*

• Select 'ProjectMenu'

• Select 'Background Setting'

• Select 'Log Setting'

• Select 'Log Switch'

• Enable 'LOG on'

• Select 'Log level setting'

• Enable 'DEBUG'

• Press the 'Back' key

• Select 'Dump and Log'

• Enable 'Open Dump and Log'

• Press 'Back' key 5 times to return to home screen.

• Reboot the phone.

LogCat should now work.

logcat won't let you show Debug only but you can show Debug and higher (Debug, Info, Warning, Error, Fatal) with:

adb logcat YourLogTag:D *:S

The *:S suppresses logs from other apps.

You can pipe the result through grep to only show Debug:

adb logcat YourLogTag:D *:S | grep "D YourLogTag"

If you're on zsh like on Catalina OSX instead of bash you may need to perform the following commands:

Use --- noglob adb logcat *:E --- replace the E with whatever, below.

Alternatively you can also use --- adb logcat '*:E' --- (quotes around)

V: Verbose
D: Debug
I: Info
W: Warning
E: Error
F: Fatal
S: Silent

The reason being that Zsh interprets the wildcard as you wanting to expand files ending in that letter without the quotes wrapping around or the noglob prefix.

You can create a filter for a specific application using its package name.
