File::Copy (Perl in a Nutshell, 2nd Edition)

8.98. File::Copy

Copies or moves files or filehandles from one location to another. Returns 1 on success, 0 on failure, or sets $! on error.

copy

copy (source, dest[, buffsize])

Copies source to dest. Takes the following arguments:

source: The source string, FileHandle reference, or FileHandle glob. If source is a filehandle, it is read from; if it's a filename, the filehandle is opened for reading.
dest: The destination string, FileHandle reference, or FileHandle glob. dest is created if necessary and written to.
buffsize: Specifies the size of the buffer to be used for copying. Optional.

cp (source, dest[, buffsize])

Like copy, but exported only on request:

use File::Copy "cp"

move

move (source, dest)

Moves source to dest. If the destination exists and is a directory, and the source is not a directory, then the source file is renamed into the directory specified by dest. Return values are the same as for copy.

mv (source, dest)

Like move, but exported only on request:

use File::Copy "mv"
