Having extensively used AWK and PERL, I don’t agree. AWK works for simple things, but has significant limitations especially for more complex parsing you might do in a dozen lines of PERL. Subroutines don’t return complex structures, Strict mode declaration checking, hashes, foreach style iterators are much less functional or missing in AWK. Multi layer structures are also trivial in PERL (hash table or array composed of child hash or array). Finally, AWK versus GAWK versus NAWK compatibility is an issue.
