Code:
cp -n or cp -no

Flag doesn't work.
Which Flag should I use?
PHP Code:
Try `cp --help' for more information.
cp: invalid option -- n
Try 
`cp --help' for more information.
[root@]# cp --help
Usage: cp [OPTION]... [-T] SOURCE DEST
  or:  cp [OPTION]... SOURCE... DIRECTORY
  or:  cp [OPTION]... -t DIRECTORY SOURCE...
Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY.

Mandatory arguments to long options are mandatory for short options too.
  -a, --archive                same as -dR --preserve=all
      --backup[=CONTROL]       make a backup of each existing destination file
  -b                           like --backup but does not accept an argument
      --copy-contents          copy contents of special files when recursive
  -d                           same as --no-dereference --preserve=link
  -f, --force                  if an existing destination file cannot be
                                 opened, remove it and try again
  -i, --interactive            prompt before overwrite
  -H                           follow command-line symbolic links
  -l, --link                   link files instead of copying
  -L, --dereference            always follow symbolic links
  -P, --no-dereference         never follow symbolic links
  -p                           same as --preserve=mode,ownership,timestamps
      --preserve[=ATTR_LIST]   preserve the specified attributes (default:
                                 mode,ownership,timestamps), if possible
                                 additional attributes: context, links,
                                 xattr, all
  -c                           same as --preserve=context
      --no-preserve=ATTR_LIST  don'
t preserve the specified attributes
      
--parents                use full source file name under DIRECTORY
  
-R, -r, --recursive          copy directories recursively
      
--remove-destination     remove each existing destination file before
                                 attempting to open it 
(contrast with --force)
      --
sparse=WHEN            control creation of sparse files
      
--strip-trailing-slashes remove any trailing slashes from each SOURCE
                                 argument
  
-s, --symbolic-link          make symbolic links instead of copying
  
-S, --suffix=SUFFIX          override the usual backup suffix
  
-t, --target-directory=DIRECTORY  copy all SOURCE arguments into DIRECTORY
  
-T, --no-target-directory    treat DEST as a normal file
  
-u, --update                 copy only when the SOURCE file is newer
                                 than the destination file 
or when the
                                 destination file is missing
  
-v, --verbose                explain what is being done
  
-x, --one-file-system        stay on this file system
  
-Z, --context=CONTEXT        set security context of copy to CONTEXT
      
--help     display this help and exit
      --
version  output version information and exit

By default, sparse SOURCE files are detected by a crude heuristic and the
corresponding DEST file is made sparse 
as well.  That is the behavior
selected by 
--sparse=auto.  Specify --sparse=always to create a sparse DEST
file whenever the SOURCE file contains a long enough sequence of zero bytes
.
Use --
sparse=never to inhibit creation of sparse files.

The backup suffix is `~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
The version control method may be selected via the --backup option or through
the VERSION_CONTROL environment variable.  Here are the values:

  none, off       never make backups (even if --backup is given)
  numbered, t     make numbered backups
  existing, nil   numbered if numbered backups exist, simple otherwise
  simple, never   always make simple backups

As a special case, cp makes a backup of SOURCE when the force and backup
options are given and SOURCE and DEST are the same name for an existing,
regular file.
