NAME
gfimport_text - divide and register a text file
SYNOPSIS
gfimport_text [ options ] file
DESCRIPTION
gfimport_text is a sample program for dividing a text file to file
fragments by the line and registering it to the Gfarm filesystem.
OPTIONS
- -H hostfile
- specifies a list of filesystem nodes. The hostfile consists of a hostname of a filesystem node in each line. The file is almost uniformly divided into file fragments.
- if ``-'' is specified, standard input is used to read the host list.
- -f fragment-file
- specifies a fragment-file that consists of a fragment size in byte and a filesystem node separated by a white space in each line.
- if ``-'' is specified, standard input is used.
- -o gfarm-URL
- specifies an output file.
- -? displays a list of command options.
EXAMPLES
- IMPORTING BY SPLITTING TO SPECIFIED NUMBER OF FRAGMENTS
- The following is an example using gfimport_text to import a source_file as gfarm:file by splitting to 8 fragments.
- gfsched -N 8 | gfimport_text -H - -o gfarm:file source_file
- IMPORTING BY SPLITTING TO SPECIFIED NUMBER OF FRAGMENTS FOR PARTICULAR
- PROGRAM
The following is an example using gfimport_text to import a source_file as gfarm:file by splitting to 8 fragments to be processed by gfarm:prog program. - gfsched -N 8 -p gfarm:prog | gfimport_text -H - -o gfarm:file source_file
- IMPORTING INTO SAME DISPOSITION WITH AN EXISTING GFARM FILE
- The following is an example using gfimport_text to import a source_file as gfarm:file into same disposition with existing file gfarm:template.
- gfsched gfarm:template | gfimport_text -H - -o gfarm:file source_file
