Net::FTPServer::Full::FileHandle - The full FTP server personality

SYNOPSIS

  use Net::FTPServer::Full::FileHandle;

DESCRIPTION

Top

METHODS

Top

$dirh = $fileh->dir;

Return the directory which contains this file.

$fh = $fileh->open (["r"|"w"|"a"]);

Open a file handle (derived from IO::Handle, see IO::Handle(3)) in either read or write mode.

Return the file or directory status. The fields returned are:

  $mode     Mode        'd' = directory,
                        'f' = file,
                        and others as with
                        the find(1) -type option.
  $perms    Permissions Permissions in normal octal numeric format.
  $nlink    Link count
  $user     Username    In printable format.
  $group    Group name  In printable format.
  $size     Size        File size in bytes.
  $time     Time        Time (usually mtime) in Unix time_t format.

In derived classes, some of this status information may well be synthesized, since virtual filesystems will often not contain information in a Unix-like format.

$rv = $handle->move ($dirh, $filename);

Move the current file (or directory) into directory $dirh and call it $filename. If the operation is successful, return 0, else return -1.

Underlying filesystems may impose limitations on moves: for example, it may not be possible to move a directory; it may not be possible to move a file to another directory; it may not be possible to move a file across filesystems.

$rv = $fileh->delete;

Delete the current file. If the delete command was successful, then return 0, else if there was an error return -1.

If the current file is really a symbolic link, read the contents of the link and return it.
