File Permissions and the chmod/chgrp/chown commands

  • The username followed by a dot or colon and no groupname changes the

    user ownership as specified and changes the group ownership to the specified

    user?s login group.

  • If the colon or dot and groupname are specified without a username,

    then only the groupownership is changed. This is effectively the same as

    the chgrp command.


  • If the username is not followed by a dot or a colon, then only the

    user ownership is changed.


  • The

    chgrp command

    The chgrp command is used to change the group ownership of one or more files

    or directories. Its general syntax is :

    chgrp [-Rcfv] groupname foo.txt

    The flags used here are also the same as those in the chmod command. The

    changes in ownership are applied to the groupname and the filename specified.
