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.
