This specifies the FIFO option.
When the vales of the specified key fields are equal, the firstly input records are output first. This option is effective in the sort option. When omitted, the output order is not necessarily first-in first-out. When specified at the same time as the Merge option (-m), the Copy option (-c), the Summation field option (-g), and the Suppression option (-u), the specification of the first-in first-out (FIFO) option is disregarded.
Format
-f
Note
The FIFO option (-f) takes priority over environment variable BSORT_FIFO.
