find ./ -name "Thumbs*" -print0 | xargs -0 ls
-print 0 on "find"
"It prints the pathname of the current file to standard output, followed by an ASCII NUL character"
-0 on "xargs"
"Change xargs to expect NUL (``\0'') characters as separators, instead of spaces and newlines.
This is expected to be used in concert with the -print0 function in find(1)."
xargs 와 find 를 조합하라고, -0 와 -print0 를 조합해서 사용하라고, man page에 소상히 적어 두었군요 :)
