NAME

       gfrm - remove Gfarm files, directories, or file replicas

SYNOPSIS

       gfrm [ -frRnqv ] [ -I file-section ] [ -h filesystem-node ] [ -D domain-name ] [ -H hostfile ] [ -N num-of-replicas ] [ -j num-of-threads ]
       gfarm-URL ...

DESCRIPTION

       gfrm removes each specified file.  It does not remove directories unless the -r or -R option is specified.  '.' or '..' cannot be removed.

       When the -I option is specified, gfrm removes the specified file section.  File section is an architecture name for executable files, or  a
       fragment index for a regular file.

       With  the -h, -D, or -H option, gfrm removes file replicas of each specified file or file section on the specified filesystem node(s).  All
       file replicas of a file cannot be removed, unless the -f option is specified.

OPTIONS

       -f     Even when all file replicas are specified by the -h, -D, or -H option, forcibly deletes all the file replica.   In  this	case,  the
	      specified file will be deleted.

       -j num-of-threads
	      Specifies  the  number of threads to delete file replicas simultaneously.  This option is only available when gfrm is compiled by an
	      OpenMP C compiler.

       -n     Prints file names to be deleted, but does not delete them.

       -q     Does not print any verbose message.

       -r, -R Removes all entries under the directories specified by the command-line argument recursively.

       -v     Prints verbose messages.

       -h filesystem-node
	      Specifies a filesystem node from which file replicas will be removed.  With the -I option, a file replica of the specified file sec-
	      tion will be removed.

       -D domain-name
	      Specifies a domain name of filesystem nodes on which file replicas will be removed.  With the -I option, a file replica of the spec-
	      ified file section will be removed.

       -H hostfile
	      Specifies a hostfile that lists filesystem nodes on which file replicas will be removed.	With the -I option, a file replica of  the
	      specified file section will be removed.

	      if ``-'' is specified, standard input is used to read the host list.

       -I file-section
	      Specifies  the  file section to be removed.  File section is an architecture name, such as sparc-sun-solaris8, for executable files,
	      and a fragment index for regular files.

       -N num-of-replicas
	      Specifies the maximum number of file replicas.  If files has more number of file replicas than specified, reduce the number of  file
	      replicas.

NAME

       gfrep - replicate Gfarm files

SYNOPSIS

       gfrep  [  -mnqvx  ]  [ -S source-domainname ] [ -D destination-domainname ] [ -h source-hostfile ] [ -H destination-hostfile ] [ -N num-of-
       replicas ] [ -j num-of-threads ] path ...

DESCRIPTION

       gfrep creates specified number of replicas of Gfarm files specified by the path to specified set of destination hosts.  When set of  source
       hosts  are specified, only files stored on the set of source hosts are replicated.  A set of hosts can be specified by a domain name and/or
       a host file.  When both a domain name and a host file are specified, a set of hosts is determined by both conditions.

       If the path parameter is a directory, files under the directory will be copied recursively.

OPTIONS

       -S source-domainname
	      Specifies the domain name of source filesystem nodes from which replicas will be copied.

       -D destination-domainname
	      Specifies the domain name of destination filesystem nodes to which replicas will be copied.

	      If neither this nor the -H option is specified, replicas may be copied to any available host.

       -h source-hostfile
	      Specifies a file which describes hostnames of source filesystem nodes from which the replica will be made.  The source-hostfile con-
	      sists of a filesystem node name on each line.

	      if ``-'' is specified, standard input is used to read the host list.

       -H destination-hostfile
	      Specifies a file which describes hostnames of destination filesystem nodes on which the replica will be made.  The destination-host-
	      file consists of a filesystem node name on each line.

	      if ``-'' is specified, standard input is used to read the host list.

       -N num-of-replicas
	      Specifies the required number of file replicas, counting already existing ones.  If there are a sufficient number of replicas in the
	      destination hosts, neither any copying nor any removal will be done.

	      If this option is not specified, -N 1 is assumed.

       -j num-of-threads
	      Specifies  the number of threads to create file replicas simultaneously.	This option is only available when compiled by an OpenMP C
	      compiler.  By default, it will be the smallest among the number of total files, the number of source hosts, and the number of desti-
	      nation hosts.

       -m     Lets gfrep command do a migrate/move, instead of doing replication.

       -x     Removes file replicas when a set of destination nodes has more file replicas than specified.

       -n     Displays files to be replicated, but does nothing.

       -q     Suppresses non-error messages.

       -v     Displays verbose output.

       -?     Displays a list of command options.

BUGS

       A source host is not always selected within a set of source hosts.
