Using the find -exec Command Option

5. The Delimiter

We need to provide the find command with a delimiter so it'll know where our -exec arguments stop.

Two types of delimiters can be provided to the -exec argument: the semi-colon(;) or the plus sign (+).

As we don't want our shell to interpret the semi-colon, we need to escape it (\;).

The delimiter determines the way find handles the expression results. If we use the semi-colon (;), the -exec command will be repeated for each result separately. On the other hand, if we use the plus sign (+), all of the expressions' results will be concatenated and passed as a whole to the -exec command, which will run only once.
