dpns-rm(1)

NAME

dpns-rm - remove DPNS files or directories in the name server

SYNOPSIS

dpns-rm [-a] [-f] [-i] filename...

dpns-rm [-f] [-i] -r dirname...

DESCRIPTION

dpns-rm removes DPNS files or directories in the name server. For directories either -r or -R must be present. For regular files, it calls dpns_unlink while for directories, it calls dpns_rmdir.

This requires write permission in the parent directory and the file itself. If write permission on an entry is denied, the standard input is a terminal and the -f option is not given, the prompt "override write protection" appears and if the response is not y, the entry is not deleted. Entries directly under a protected directory are never deleted.

path

specifies the DPNS pathname. If path does not start with /, it is prefixed by the content of the DPNS_HOME environment variable.

OPTIONS

The following options are supported:

-a

Remove the metadata information about a file and the metadata information about the replicas that it may have. Remember that this is a metadata-only operation, it does not remove the replicas physically from the disk. Removing metadata entries about replicas without removing the replicas from the disks leads to non-reachable files on disk. Applies only to files, not directories.

-f

Do not give an error message if the file/directory does not exist.

-i

Request acknowledge before removing each individual entry.

-R

Recursive mode (equivalent to -r).

-r

Recursive mode.

EXIT STATUS

This program returns 0 if the operation was successful or >0 if the operation failed.
