命令：chown -r xxxx：xxxx 文件夹

通过chown改变文件的拥有者和群众，修改操作权限要求为管理员。

chown命令详解：

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  
      --dereference      affect the referent of each symbolic link (this is  
                         the default), rather than the symbolic link itself  
  -h, --no-dereference   affect each symbolic link 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 \`/'  
  -f, --silent, --quiet  suppress most error messages  
      --reference=RFILE  use RFILE's owner and group rather than  
                         specifying OWNER:GROUP values  
  -R, --recursive        operate on files and directories recursively  
  -v, --verbose          output a diagnostic for every file processed  
  
  
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 and exit  
  
  
Owner is unchanged if missing.  Group is unchanged if missing, but changed  
to login group if implied by a \`:' following a symbolic OWNER.  
OWNER and GROUP may be numeric as well as symbolic.  
  
  
Examples:  
  chown root /u        Change the owner of /u to "root".  
  chown root:staff /u  Likewise, but also change its group to "staff".  
  chown -hR root /u    Change the owner of /u and subfiles to "root".
