The where command shows the call stack for your current process. To print a procedure traceback:
where
To print the number top frames in the traceback:
where number
To start the traceback from frame number:
where -f number
where -h
where -q
To include function args and line info:
where -v
Any of the previous commands may be followed by a thread or LWP ID to view the call stack.
Use the hide command to list the stack frame filters currently in effect.
To hide or delete all stack frames matching a regular expression:
hide [ regexp ]
The regular expression matches either the function name, or the name of the loadobject, and is a sh or ksh file matching style regular expression.
Use unhide to delete all stack frame filters:
unhide 0
Because the hide command lists the filters with numbers, you can also use the unhide command with the filter number:
unhide [ number | regexp ]
