chgrp

Changes the user group of a file in the LSF data management cache.

Options

Change user group after stage out.

bdata chgrp [-dmd cluster_name] -g user_group_name "[host_name:]abs_file_path"

bdata chgrp [-dmd cluster_name] -g user_group_name "[host_name:]abs_folder_path/[*]"

Change user group after stage in.

bdata chgrp [-dmd cluster_name] -g user_group_name -tag tag_name

Description

Note: The CACHE_ACCESS_CONTROL = Y parameter must be configured in the lsf.datamanager file to use the bdata chgrp command. Only the owner of the file, folder, or data tag can change the group access with the bdata chgrp command.

Change group after stage out

Use the bdata chgrp -g group_name command and specify the name of a data file or folder that is already staged in to the cache. The chgrp command changes the user group of a transferred data file and the directory it is in. The file must be in the transferred state or idle state for the command to succeed.

If you specify a folder, either recursive (abs_folder_path/) or non-recursive (abs_folder_path/*), the folder must be in the transferred state or idle state. The user group of both the folder and its contents are changed. The top-level folder permissions are set to 0770 (rwxrwx---). The permissions of other directories under the top-level directory are set to 0750 (rwxr-x---).

When you use the asterisk character (*) at the end of the path, the data requirements string must be in quotation marks.

If you specify an optional host name (host_name:abs_file_path), the bdata chgrp command changes the user group of the files or folders that are staged in from the specified host.

Change group after stage in

Use the bdata chgrp -g group_name command and specify a tag name to change the group of all the files in the cache that is associated with the tag to the group name specified by group_name. The group of the tag directory and its contents is changed. The command sets the permissions of the top-level tag directory to 0770 (rwxrwx---). The permission of other directories in the top-level tag directory is set to 0750 (rwxr-x---).

The command is equivalent to the chmod ug+r, o-rwx command, and sets the owner and group read permissions of all files (not directories).
