Edit - Unix & Linux Stack Exchange

You are not logged in. Your edit will be placed in a queue until it is peer reviewed.

We welcome edits that make the post easier to understand and more valuable for readers. Because community members review edits, please try to make the post substantially better than how you found it, for example, by fixing grammar or adding additional resources and hyperlinks.

Note that in practice in most shells, (a;b) is already the same as (a;exec b) as shells optimize out the fork for the last command in a subshell. The only exceptions seem to be bash and mksh. Using exec helps to guarantee it.
