Many simple cases go with echo instead of find, so that the stupid
"-maxdepth 1 -mindepth 1" phrase can be eliminated.
E.g., following lines are equivalent in sh and t?csh:
% mv bla.*.1 dir/
% echo bla.*.1|xargs -J% mv % dir/
Or even to (override 5000 limit may be necessary):
% echo bla.*.1 dir/|xargs mv
Hope this reduces your typing efforts.
