Synopsis
close filehandle
Closes the file, socket, or pipe associated with the
given filehandle. You don’t have to close
filehandle if you are immediately going
to do another open on it, since
the next open will close it for
you. However, an explicit close
on an input file resets the line counter ($.), while the implicit close done by open does not. Closing a pipe will wait
for the process executing on the pipe to complete and will prevent
the script from exiting before the pipeline is finished. Also,
closing a pipe explicitly puts the status value of the command
executing on the pipe into $?.
filehandle may be an expression
with a value that gives a real filehandle name. It may also be a
reference to a filehandle object returned by some of the
object-oriented I/O packages.
