jmap -histo with a specific object at Windows

Question

While testing my jar application at Linux I use the command line below to track the usage/memory load of a specific object (eg JButton).

jmap -histo:live <pid> | grep JButton

Which results:

35:            24          11136  javax.swing.JButton
99:            31           2728  javax.swing.JButton$AccessibleJButton

Now I'm trying to do the same with Windows but I cannot find a similar command (like grep) to track a specific object. jmap -histo[:live] <pid> provides a full list of all objects. Does Windows have similar tools for such usage or an alternate way?

You can use [`find "JButton"`](https://technet.microsoft.com/en-us/library/bb490906.aspx). Note that the quotes are required. — Holger, Jun 13 '17 at 06:43
@Holger I just tested it and works just fine. Thank you very much. — Zerthimon, Jun 13 '17 at 07:08

I tested the suggestions from comments and we have an answer now:

jmap -histo:live <pid> | grep JButton

from Linux is equivalent to:

jmap -histo:live <pid> | find "JButton"

or

jmap -histo:live <pid> | findstr JButton

from Windows.
