Last Count
Each time Split runs a parameter file, it keeps track of the number of bytes
it read from the input file and saves this information in the parameter file.
Split can then start where it last left off. This is done by clicking the
Offsets button and selecting the Last Count option. This feature may be
used to process only the new data from a file in which new data are being
appended periodically to the data file.
When using the Last Count option, if the Start and Stop
Conditions are specified, they must exist in the newly
appended data or Split will never begin execution. CAUTION
Because Last Count keeps track of the number of bytes in
the file, if you delete data from the beginning of a file, Last
Count will not work properly.
