copyFile -package:Cabal
Copy a file with its permissions. If the destination file already
exists, it is replaced atomically. Neither path may refer to an
existing directory. No exceptions are thrown if the permissions could
not be copied.

copyFile old new copies the existing file from
old to
new. If the
new file already exists,
it is atomically replaced by the
old file. Neither path may
refer to an existing directory. The permissions of
old are
copied to
new, if possible.
Copy the content and permissions of a file to a new entry in the
filesystem. If a file already exists at the new location, it will be
replaced. Copying a file is not atomic.
This computation throws
IOError on failure. See “Classifying
I/O errors” in the
System.IO.Error documentation for
information on why the failure occured.
Since: 0.1.1
Lifted version of
copyFile with well-typed filepaths.
This will copy any file directly by using a system call
Copy a file with its associated metadata. If the destination file
already exists, it is overwritten. There is no guarantee of atomicity
in the replacement of the destination file. Neither path may refer to
an existing directory. If the source and/or destination are symbolic
links, the copy is performed on the targets of the links.
On Windows, it behaves like the Win32 function
CopyFile, which
copies various kinds of metadata including file attributes and
security resource properties.
On Unix-like systems, permissions, access time, and modification time
are preserved. If possible, the owner and group are also preserved.
Note that the very act of copying can change the access time of the
source file, hence the access times of the two files may differ after
the operation completes.
Truncate the destination file and then copy the contents of the source
file to the destination file. If the destination file already exists,
its attributes shall remain unchanged. Otherwise, its attributes are
reset to the defaults.

Copies one filename to another in binary mode.
Please note that the Unix permission bits on the output file cannot be
set due to a limitation of the Haskell
openBinaryFile function.
Therefore, you may need to adjust those bits after the copy yourself.
This function is implemented using
hBlockCopy internally.
Copies one filename to another in text mode.
Please note that the Unix permission bits are set at a default; you
may need to adjust them after the copy yourself.
This function is implemented using
hLineCopy internally.
copyFile' old new copies the existing file from old
to new. The old file will be tracked as a
dependency. Also creates the new directory if necessary.
copyFileChanged old new copies the existing file from
old to new, if the contents have changed. The
old file will be tracked as a dependency. Also creates the
new directory if necessary.
