Basically it just means find is going to pass the files it found to what ever command you specify. In your example, find going to locate core files and send them as output to the rm command. It's just a fancy way to find stuff and delete it at the same time.

find(n) [incr Tcl] find(n)
__________________________________________________________________________________________________________________________________________________
NAME
find - search for classes and objects
SYNOPSIS
itcl::find option ?arg arg ...?
_________________________________________________________________
DESCRIPTION
The find command is used to find classes and objects that are available in the current interpreter. Classes and objects are reported first
in the active namespace, then in all other namespaces in the interpreter.
The option argument determines what action is carried out by the command. The legal options (which may be abbreviated) are:
find classes ?pattern?
Returns a list of [incr Tcl] classes. Classes in the current namespace are listed first, followed by classes in all other names-
paces in the interpreter. If the optional pattern is specified, then the reported names are compared using the rules of the "string
match" command, and only matching names are reported.
If a class resides in the current namespace context, this command reports its simple name--without any qualifiers. However, if the
pattern contains :: qualifiers, or if the class resides in another context, this command reports its fully-qualified name. There-
fore, you can use the following command to obtain a list where all names are fully-qualified:
itcl::find classes ::*
find objects ?pattern? ?-class className? ?-isa className?
Returns a list of [incr Tcl] objects. Objects in the current namespace are listed first, followed by objects in all other names-
paces in the interpreter. If the optional pattern is specified, then the reported names are compared using the rules of the "string
match" command, and only matching names are reported. If the optional "-class" parameter is specified, this list is restricted to
objects whose most-specific class is className. If the optional "-isa" parameter is specified, this list is further restricted to
objects having the given className anywhere in their heritage.
If an object resides in the current namespace context, this command reports its simple name--without any qualifiers. However, if
the pattern contains :: qualifiers, or if the object resides in another context, this command reports its fully-qualified name.
Therefore, you can use the following command to obtain a list where all names are fully-qualified:
itcl::find objects ::*
