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 section 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
specified 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.
