-exec command ;
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 action; you should use the -execdir option instead.

-exec command {} +
This variant of the -exec action runs the specified command on the selected files, but the command line is built by
appending each selected file name at the end; the total number of invocations of the command will be much less than the
number of matched files. The command line is built in much the same way that xargs builds its command lines. Only one
instance of `{}’ is allowed within the command. The command is executed in the starting directory.
