This is pstree-2.36p1 as installed by the latest
package on current/macppc (MacMini).
Running just pstree(1) by itself works fine,
but piping or redirecting the output does not.
For example, 'pstree | cat' or 'pstree | hexdump'
or 'pstree > ps' result in just the newlines.
Attached see a full script(1) of the session.
It happens in both xterm and the console,
but not on any other architecture I have.
It works as expected on i386, amd64, and armv7.
(See dmesg below).
Am I missing something obvious?

Comment:
list processes as a tree
Description:
This is pstree. It is a small program that shows the ps
listing as a tree (as the name implies...). It has several options
to make selection criteria and to change the output style.
For that it uses the output of /bin/ps.
