"sent" to a reject file is somewhat ambiguous, do you mean write a copy of the line to the reject file or delete it from the original and write it to the reject file?

You can use the split shell command to split the file into manageable chunks if it is too big for awk. See the man file for split: -

Code:
man split

wcscspn - search a wide-character string for any of a set of wide characters SYNOPSIS
#include <wchar.h> size_t wcscspn(const wchar_t *wcs, const wchar_t *reject); DESCRIPTION

The wcscspn() function returns the number of wide characters in the longest initial segment of wcs which consists entirely of wide-charac- ters not listed in reject. In other words, it returns the position of the first occurrence in the wide-character string wcs of any of the characters in the wide-character string reject, or wcslen(wcs) if there is none.
