Shell Programming and Scripting

Thanks Gneen for the correction, hadn't thought about that.

Believe

let hline=$((1+($tline/2)))

is what you meant to type. Since adding one to the tline causes the issue to move from odd lines to even lines, and I think what you pointed out was that the line to be split (hline) would have to be 1 more than the true half to get only 2 files.

Again thanks for finding the error in logic.

thanks for the advice guys. unfortunately im not allowed to use SED or AWK to complete this script.
