-exec와 관련된 것으로 기억해서 맨 페이지를 보니 다음과 같이 나오네요.
(번역은 잘 못하겠습니다. OTL)

Execute command;
true if 0 status is returned.
All following arguments to find are taken to be arguments
to the command until an argument consisting of ‘;’ is encountered.
The string ‘{}’ is replaced
by the current file name being processed everywhere it occurs
in the arguments to the command,
not just in arguments where it is alone,
as in some versions of find.
Both of these constructions might need to be escaped (with a ‘\’)
or quoted to protect them from expansion by the shell.
See the EXAMPLES section for examples of the use of the ‘-exec’ option.
The specified command is run once for each matched file.
The command is executed in the starting directory.
There are unavoidable security problems surrounding use of the -exec option;
you should use the -execdir option instead.
