Topic: Shell-procedure creation

Hello, help, please. Very long I sit with this problem, but I can not solve it in any way. It is necessary to implement shell-procedure which requests input sequentially several numbers with signs and displays 2 lists of numbers - positive and negative.  all textbook of methodics, but unfortunately, anything carried out the useful. I ask from you the help.
I apply the code which is available for me at present (found it on open spaces of this forum). Unfortunately, errors are produced:

[$I-lt 0] && echo "$I"
