break

Exit from a while, for, or do loop.

close(expr)

close(expr, how) {G}

In most implementations of awk, you can only have up to ten files

and one pipe open simultaneously. Therefore, POSIX awk provides

a close( ) function that allows you to close a file or a pipe. It takes

the same expression that opened the pipe or file as an argument.

This expression must be identical, character by character, to the

one that opened the file or pipe—even whitespace is significant.

In the second form, close one end of either a TCP/IP socket or a

two-way pipe to a coprocess. how is a string, either "from" or "to".

Case does not matter.
