-print0
print the full file name on the standard output, followed by a null character (instead of the newline charactes that -print uses)
-exec command ;
{} expands to the filename of each file or directory found with find, ; Says that for each found result, the command (in this case ‘grep’) is executed once with the found result
-exec command {} +
run 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.

find . -exec xxx {} ;
Find configuration data
find /etc -type f -exec grep -FHi “ENCRYPTION_PASSWORD” {} +

-t
print each command prior execution
-p
print each command and ask to execute it
-x
