关于chown命令：

系统管理员使用Chown命令以更改Linux文件系统上的文件和目录的所有权。
它允许超级用户更改和限制对Linux系统上的文件和目录的访问权限。

例子：

以下是如何运行和使用ubuntu Linux的智能的一些示例。

运行以下命令设置john成为Confidential的所有者。

chown john Confidential

设置Confidential的所有者为john，所有组为private

chown john:private Confidential

如果我们未登为root帐户，则可能必须使用sudo命令。

sudo chown john:private Confidential

要更改整个目录的所有权和组，包括子目录，请添加-r选项。

sudo chown -R john:private directories

使用-help选项：

Usage: chown [OPTION].  [OWNER][:[GROUP]] FILE. 
  or:  chown [OPTION].  --reference=RFILE FILE. 
Change the owner and/or group of each FILE to OWNER and/or GROUP.
With --reference, change the owner and group of each FILE to those of RFILE.
  -c, --changes          like verbose but report only when a change is made
  -f, --silent, --quiet  suppress most error messages
  -v, --verbose          output a diagnostic for every file processed
      --dereference      affect the referent of each symbolic link (this is
                         the default), rather than the symbolic link itself
  -h, --no-dereference   affect symbolic links instead of any referenced file
                         (useful only on systems that can change the
                         ownership of a symlink)
      --from=CURRENT_OWNER:CURRENT_GROUP
                         change the owner and/or group of each file only if
                         its current owner and/or group match those specified
                         here.  Either may be omitted, in which case a match
                         is not required for the omitted attribute
      --no-preserve-root  do not treat '/' specially (the default)
      --preserve-root    fail to operate recursively on '/'
      --reference=RFILE  use RFILE's owner and group rather than
                         specifying OWNER:GROUP values
  -R, --recursive        operate on files and directories recursively
The following options modify how a hierarchy is traversed when the -R
option is also specified.  If more than one is specified, only the final
one takes effect.
  -H                     if a command line argument is a symbolic link
                         to a directory, traverse it
  -L                     traverse every symbolic link to a directory
                         encountered
  -P                     do not traverse any symbolic links (default)
      --help     display this help and exit
      --version  output version information an
