"How to observe stderr of a process" is a recently asked question seen
on the the observability-discuss forum on opensolaris.org, ending
with:
I've tried "truss", but it outputs only part of the buffers being written.
As always, a simple answer show up very quickly from a community member, in this case James Carlson:
Have you tried the "-w" option on truss? "truss -t\!all -w2" should do what you're asking.
Feel good to have lots of nice people on these lists!
