NAME
Copy - Copy files.
SYNOPSIS
Copy From To/a ALL/s QUIET/s BUF=BUFFER/k CLONE/s DATES/s
NOPRO/s COM/s FLAGS/k QUICK/s
DESCRIPTION
COPY duplicates the contents of the file or files (if
wildcards or a directory is given) of its FROM argument to
the file or directory specified in its TO argument,
overwriting any existing file or files of the same names.
FILE SPECIFICATION
The From argument may be a file, a directory or a wildcard
pattern. You can use a dot '.' as either the From or To
directory to indicate the current directory.
If the From argument is a directory or a pattern, the To
argument is assumed to be a directory or destination
replacement pattern. If the directory specified in the To
argument does not exist, it will be created for you.
If you include wildcard characters in the To argument, these
are taken to be a request to use a pattern substitution for
the destination filename. The expected syntax is:
<optional_prefix>*<optional_postfix>
You may specify neither, one, or both of these optional
tags. If you exceed the length of an AmigaDOS filename (30
characters as of this writing) the name will be silently
truncated. You can also indicate which portion of the From
filename you want to be replaced by using the wildcard
characters in the source pattern. The rule followed is that
any constant (i.e., non-wildcarded) portion of the
source pattern is discarded. As an example, the
command:
Copy l* start*end
will copy all files beginning with an 'l'. The destination
names these will be copied to will be formed by removing the
'l', and sticking 'start' on the front, and 'end' on the
back. So, for example, the file 'LXXX' would be copied to
the file 'startXXXend'. If the start or end patterns are
omitted, these are regarded as null strings.
OPTIONS
ALL Copies ALL the files from the source directory to the
destination directory or device. This will recursively
descend all subdirectories found in the From directory,

and create them (if they do not already exist) in the
To directory. Without this switch, only the first
level of the directory hierarchy will be duplicated.
QUIET
Performs a Copy without reporting what it is doing.
This is useful for doing copies in the background, when
you do not wish to be disturbed by informative
messages. Note that errors will still be reported.
BUF=BUFFER
This allows you to specify the number of 512 byte
buffers used during the copy. Unlike the Commodore
Copy, which uses a fixed number of buffers if this
option is not specified (currently, 200 buffers),
the ARP Copy sets its internal buffer size
intelligently as a function of how much memory your
system contains and the size of the file to be copied.
Using this option overrides this intelligent behavior.
CLONE
This instructs Copy to duplicate the date, comments and
protection bits (except the archive bit) of the
original file. The default is to Copy only the
protection bits. (also see Environment, below).
DATES
This option instructs Copy to duplicate the datestamp
(also see Environment, below).
NOPRO
By default, Copy duplicates the protection bits of the
file(s) (except the archive bit). Using this option
will override this behavior, and cause the file to be
created with the current system default protection
(also see Environment, below).
COM This forces Copy to duplicate the comment for the file.
The default is not to duplicate the comment (also see
Environment, below).
QUICK
This ARP addition is a highly useful option which will
duplicate files only if the destination file does not
exist or is not the same. Copy uses the Datestamp,
Filesize, Protect bits, and also the Filenote (but only
if you have enabled copying filenotes) to determine
whether or not the file is the same. Since a byte by
byte compare is not done, it is possible to fool Copy.
However, in normal operation of the Amiga, this
dramatically speeds up Copies between directories and is
perfectly safe (also see Environment, below).

FLAGS
You can override the current setting of your
environment flags using this keyword. Any option
specified on the command line overrides the default
settings specified by the copyflags environment
variable. This keyword takes a string of the same type
used for the copyflags variable. For a discussion of
these flags, see Environment, below.
ENVIRONMENT
If you prefer a behavior for copy other than the default,
you can specify this behavior permanently by setting a value
for the copyflags environment variable. This variable takes
a string of characters composed of the following:
N Always copy filenotes (see COM, above).
C Always copy original datestamp (see DATES, above).
Q Always copy QUICK (see QUICK, above).
P Never copy protection flags (see NOPRO, above).
O This flag does not correspond to any command line
arguments. When this flag is set, Copy will only
duplicate files which already exist in the destination
directory, it stands for 'OLD', and essentially
performs an update operation. This is extremely useful
when trying to update old software with new software.
These flags can be overridden by using a command line
option, or by using the FLAGS keyword to specify new ones.
Note also that case is not significant. You can set the
copyflags variable using Set, SetEnv, or directly from the
command line if you are using Ash (the Arp Shell) as shown
below:
Set copyflags=CQ
SetEnv copyflags=CQ
copyflags=CQ ; This only works in ASH
The settings shown above is perhaps the most common: it
enables copying datestamps, protection bits, and the QUICK
option.
EXAMPLE
To perform an update from one directory to another without
using copyflags, use:
Copy NewDir OldDir FLAGS=O
