Copy(V1.3,2.x,3.x) (in the C: directory))
NAME
Copy - Copy files.
SYNOPSIS
Copy From To ALL QUIET BUF=BUFFER CLONE DATES
NOPRO COM FLAGS QUICK
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.
Double quotes "" can be used to refer to the current
directory.
If you copy a file, you may give that file the same
name or a different name as the original. If the
destination has the same name as the original then the
new copy will replace it.
Copy can duplicate many copies of a file to the same
directory if dirrerent names are used. It can also
duplicate files to many different directories.
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. As an example, the
command:
Copy l#? TO Ram:
will copy all files beginning with an 'l' to the Ram:
directory.
In 1.3 you CANNOT use wildcards for Directory names,
only file names. 2.x/3.x allows this.
1.3 will not let you copy a file to a directory that
does not exist. In 2.x/3.x COPY will create a directory
if one does not exist.
If you copy a file to the same directory it cannot
have a file with that same name of the protection bit is
set on the file being copied to.
The from statement is not needed as long as the
source and target files are in the appropriate order. If
the orders are changed (Copy To filename FROM filename),
the FROM is required.
If you don't specify a directory, but the TO keyword
is used, then the current directory is copied to the
destination. For instance, COPY TO Work: will copy the
entire contents of the current directory to Work:.
Devices such as PRT: and SPEAK: can be designated as
the destination of any file being copied.
2.x/3.x Only: You can chose multiple FROM files as
well as multiple TO files.
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). This is
the same as using both the DATE and COM keywords.
DATE
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.
NOREQ
Normally, whenever you try to copy to a directory
that does not exist a requestor will pop up asking you to
insert it. If you do not want that little requestor,
then use this keyword. This is useful for when you want
to write a script for someone else who does not have a
device you want to try to copy to (such as a printer or a
speech device- speech devices were removed from the
Workbench with 2.0).
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 the Shell instead
of the CLI.
Set copyflags=CQ
SetEnv copyflags=CQ
The settings shown above is perhaps the most common:
it enables copying datestamps, protection bits, and the
QUICK option.
EXAMPLE
1. To perform an update from one directory to another
without using copyflags, use:
Copy NewDir OldDir FLAGS=O
2. To copy a file called TheFile to OtherFile in the
same dir:
Copy TheFile Otherfile
or
Copy TheFile to Otherfile
or
Copy To Otherfile From TheFile
3. To copy all the files from Df0: to Work:
Copy Work: df0:
4. To copy all files and subdirectories from df0: to
Work:
Copy Df0: Work: ALL
5. Copy all the files in the current directory to
Ram:
Copy "" Ram:
6. To Copy a file called Dudes in the current
directory to a file with the same name to a directory
called :WildWest/Cowboys, which is on the same disk:
Copy Dudes :WildWest/Cowboys
7. To Copy selected files from the current directory
to the Stuff: directory.
Copy "" Stuff:
