Re^8: Split tab-separated file into separate files, based on column name (open on demand)

> Yes, but the optional implicit outer loops in Perl are different from the implicit outer loop in Awk — Awk's syntax is built around its implicit outer loop, using PATTERN-RULE pairs, while Perl's implicit outer loops are purely for convenience. I have always just written an outer loop explicitly even in one-liners.

I have trouble understanding what you mean.

AFAICS are awk's PATTERN-RULES nothing more than if(PATTERN) { RULE } in Perl, plus some special defaults (no Rule means print)

Could you give an example where perl -n fails to allow the same semantic like in awk?

The semantics are the same but the syntax is different and the input range operator in Awk only works in pattern syntax; Perl's equivalent `..` and `...` operators work anywhere. The Awk syntax is more elegant for some problems — and completely unusable for most problems better solved in Perl.	[reply] [d/l] [select]
