(info "(find) Directories") says -- Option: -maxdepth levels Descend at most LEVELS (a non-negative integer) levels of directories below the command line arguments. '-maxdepth 0' means only apply the tests and actions to the command line arguments.
-- Option: -mindepth levels Do not apply any tests or actions at levels less than LEVELS (a non-negative integer). '-mindepth 1' means process all files except the command line arguments. OK that is great, but not clear without examples. Something like $ find -name Makefile ./comm/radio/radioscanningtw/maps/Makefile ./comm/air/m750/programs/a/Makefile ./comm/air/routes/programs/Makefile $ find -maxdepth 4 -name Makefile $ find -maxdepth 5 -name Makefile ./comm/radio/radioscanningtw/maps/Makefile ./comm/air/routes/programs/Makefile etc.
