File::NCopy(3) User Contributed Perl Documentation File::NCopy(3)NAMEFile::NCopy - Deprecated module. Use File::Copy::Recursive instead.
Copy file, file. Copy file[s] | dir[s], dir
SYNOPSIS
use File::NCopyqw(copy);
copy "file","other_file";
copy "file1","file2","file3","directory";
# we want to copy the directory recursively
copy \1,"directory1","directory2";
copy \1,"file1","file2","directory1","file3","directory2","file4",
"directory";
# can also use references to file handles, this is for backward
# compatibility with File::Copy
copy \*FILE1,\*FILE2;
copy \*FILE1,"file";
copy "file1",\*FILE2;
# we don't specify \1 as the first argument because we don't want to
# copy directories recursively
copy "*.c","*.pl","programs";
copy "*", "backup";
use File::NCopy;
# the below are the default config values
$file = File::NCopy->new(
'recursive' => 0,
'preserve' => 0,
'follow_links' => 0,
'force_write' => 0,
'set_permission' => \&File::NCopy::u_chmod,
'file_check' => \&File::NCopy::f_check,
'set_times' => \&File::NCopy::s_times,
);
set_permission will take two file names, the original to get the
file permissions from and the new file to set the file permissions
for.
file_check takes two parameters, the file names to check the file to
copy from and the file to copy to. I am using flock for Unix
systems.
Default for this is \&File::NCopy::f_check. On Unix you can also use
\&File::NCopy::unix_check. This one compares the inode and device
numbers.
set_times is used if the preserve attribute is true. It preserves
the access and modification time of the file and also attempts to
set the owner of the file to the original owner. This can be useful
in a script used by root, though enyone can preserve the access and
modification times. This also takes two arguments. The file to get
the stats from and apply the stats to.
On Unix boxes you shouldn't need to worry. On other system you may
want to supply your own sub references.
$file = File::NCopy->new(recursive => 1);
$file->copy "file","other_file";
$file->copy "directory1","directory2";
$file = File::NCopy->new(u_chmod => \&my_chmod,f_check => \&my_fcheck);
$file->copy "directory1","directory2";
DESCRIPTION
File::NCopy::copy copies files to directories, or a single file to
another file. You can also use a reference to a file handle if you
wish whem doing a file to file copy. The functionality is very similar
to cp. If the argument is a directory to directory copy and the
recursive flag is set then it is done recursively like cp -R. In fact
it behaves like cp on Unix for the most part. If called in array
context, an array of successful copies is returned, otherwise the
number of succesful copies is returned. If passed a file handle, it's
difficult to make sure the file we are copying isn't the same that we
are copying to, since by opening the file in write mode it gets
pooched. To avoid this use file names instead, if at all possible,
especially for the to file. If passed a file handle, it is not closed
when copy returns, files opened by copy are closed.
copy
Copies a file to another file. Or a file to a directory. Or
multiple files and directories to another directory. Or a
directory to another directory. Wildcard arguments are expanded,
except for the last argument which should not be expanded. The
file and directory permissions are set to the orginating file's
permissions and if preserve is set the access and modification
times are also set. If preserve is set then the uid and gid will
also be attempted to be set, though this may only for for the men
in white hats. In list context it returns all the names of the
files/directories that were successfully copied. In scalar context
it returns the number of successful copies made. A directory
argument is considerd a single successful copy if it manages to
copy anything at all. To make a directory to directory copy the
recursive flag must be set.
cp Just calls copy. It's there to be compatible with File::Copy.
new If used then you can treat this as an object oriented module with
some configuration abilities.
recursive
If used as an object then you can use this to set the recursive
attribute. It can also be set when instantiating with new. The
other attributes must all be set when instantiating the object. If
it isn't specified then directories are not followed.
preserve
Attempt to preserve the last modification and access time as well
as user and group id's. This is a useful feature for sysadmins,
though the access and modification time should always be
preservable, the uid and gid may not.
follow_links
If the link is to a directory and this attribute is true then the
directory is followed and recursively copied. Otherwise a link is
made to the root directory the link points to. eg.
/sys/ is a link to /usr/src/sys/ is a link to /usr/src/i386/sys
then the link /sys/ is actually created in the source directory as
a link to /usr/src/i386/sys/ rather than /usr/src/sys/ since if the
link /usr/src/sys/ is removed then we lost the link even though the
directory we originally intended to link to still exists.
force_write
Force the writing of a file even if the permissions are read only
on it.
EXAMPLE
See SYNOPSIS.
BUGS
When following links the target directory might not exactly the same as
the source directory. The reason is that we have to make sure we don't
follow circular or dead links. This is really a feature though the
result may not quite resemble the source dir, the overall content will
be the same. :)
