This command doesn't actually exist as part of Tcl, but Tcl
will invoke it if it does exist. If the Tcl interpreter
encounters a command name for which there is not a defined
command, then Tcl checks for the existence of a command
named uuuunnnnkkkknnnnoooowwwwnnnn. If there is no such command, then the
interpreter returns an error. If the uuuunnnnkkkknnnnoooowwwwnnnn command
exists, then it is invoked with arguments consisting of the
fully-substituted name and arguments for the original non-
existent command. The uuuunnnnkkkknnnnoooowwwwnnnn command typically does things
like searching through library directories for a command
procedure with the name _c_m_d_N_a_m_e, or expanding abbreviated
command names to full-length, or automatically executing
unknown commands as sub-processes. In some cases (such as
expanding abbreviations) uuuunnnnkkkknnnnoooowwwwnnnn will change the original
command slightly and then (re-)execute it. The result of
the uuuunnnnkkkknnnnoooowwwwnnnn command is used as the result for the original
non-existent command.
