Why do you need a script? What stops you from using it as a one line command like
Code:
[ $(stat -c"%s" Table1_ins.dat) -gt 90000000000 ] && split -b5000000000 -a1 --verbose Table1_ins.dat TT_table1_ins.dat

This splits by bytes and could split half lines; use -l with an average line length to keep entire lines.
