Get package name and corr. data from file

I've been banging my head lately,trying to parse dumpsys output.

Here is the output:

I want to get the package name and the corresponding extras={} for each of them.

For example:

pkg:com.android.systemui
extras={
  .....
 }

So far I've tried:

dumpsys notification | awk '/pkg=/,/\n}/'

But without any success.

I'm a newbie to awk,and if possible I want to do it with awk or perl.Of course,any other tool like sed or grep is fine by me too,I just wanna parse it somehow. Can anyone help me?

If you have GNU awk, try the following:

awk -v RS='(^|\n)NotificationRecord\\([^=]+=' \
  'NF { print "pkg:" $1; print gensub(/^.*\n\s*(extras=\{[^}]+\}).*$/, "\\1", 1) }' file

• -v RS='(^|\n)NotificationRecord\\([^=]+=' breaks the input into records by lines starting with NotificationRecord( up to and including the following = char.

  • In effect, that means you get records starting with the package names (com.android.systemui, ...`)

• NF is a condition that only executes the following block if it evaluates to nonzero; NF is the count of fields in the record, so as long as at least 1 field is present, the block is evaluated - in effect, this skips the implied empty record before the very first line.

• print "pkg:" $1 prints the package name, prefixed with literal pkg:.

• gensub(/^.*\n\s*(extras=\{[^}]+\}).*$/, "\\1", 1) matches the entire record and replaces it with the extras property captured via a capture group, effectively returning the extras property only.
