Deleting First Few Lines:

Use 'tail -nnn' (where 'nnn' is the number of lines in the file *minus* the
number of lines at the beginning you want to delete), with output re-
directed to another file.

Deleting Last Few Lines:

Use 'head' instead of tail

Bad News:

Unfortunately, not all UNIX's have both 'head' and 'tail'
