The pattern ? matches any one character, whereas * matches any string (composed of zero, one or multiple characters). For example, *.o will match any files whose names end in .o. Therefore, the command du --exclude='*.o' will skip all files and subdirectories ending in .o (including the file .o itself). , , . coreutils: Copyright (C) 2024 Free Software Foundation, Inc. 3+: 3 . : . , . ,,info '(coreutils) du invocation'" ; 3 . . , - TODO <>. coreutils 9.5 2024 DU(1)
