例子：

以下是如何在Ubuntu Linux上运行和使用CHGRP的一些示例。

如果要将名为Companical.txt的文件的所有权更改为组名称私有，则我们可以在下面运行命令。

chgrp Private Confidential.txt

如果要将/Office/Files目录中的所有文件和文件夹的组所有权更改为员工组，则我们可以运行以下命令：

chgrp -hR Staff /office/files

如果我们未登为root帐户，则可能必须使用sudo命令它。

chgrp -hR Staff /office/files

要更改整个目录的所有权和组，包括子目录，请添加-r选项。

Usage: chgrp [OPTION].  GROUP FILE. 
  or:  chgrp [OPTION].  --reference=RFILE FILE. 
Change the group of each FILE to GROUP.
With --reference, change the group of each FILE to that 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)
      --no-preserve-root  do not treat '/' specially (the default)
      --preserve-root    fail to operate recursively on '/'
      --reference=RFILE  use RFILE's group rather than specifying a
                         GROUP value
  -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 and exit
Examples:
  chgrp staff /u      Change the group of /u to "staff".
  chgrp -hR staff /u  Change the group of /u and subfiles to "staff".
