Question

Logcat allows filtering logs but it works like that: You define filters and logcat only displays messages which matches filters. But is there a way to display all logs EXCEPT some TAGs defined by filters?

Answer 1

If you are using adb logcat you could pipe it through grep and use it’s inverted matching:
From the grep manpage:

v, –invert-match
Invert the sense of matching, to select non-matching lines.

For example:

$adb logcat | grep --invert-match 'notshownmatchpattern' 

You can extend this by using regular expressions.

Here is an example of such an expression:

"/^(?:emails|tags|addresses)"

This one would check for either of the given to occur, grep would then not list them.
