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. -? Displays a list of command options. Gfarm 13 November 2006 GFRM(1)
