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
