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 [ regular-expression ]
The regular-expression matches either the function name or the name of the load object and uses sh or ksh syntax for file matching.
Use the unhide command 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 | regular-expression ]
