Re^10: Split tab-separated file into separate files, based on column name (open on demand)

Awk does not have numerically-indexed arrays at all. There is a convention for using digit strings to emulate numeric indexing, and like Perl, Awk will convert numbers to digit strings upon demand, but Awk arrays are Perl hashes.

yes Awk is - similar to JS - using the same datatype for Arrays and Hashes, but ... > Awk does not have numerically-indexed arrays at all. Awk has implicitly numbered arrays like ARGV And `ARGV[1]` corresponds to `$ARGV[0]` in Perl Similarly will awk's `split()` index the first element with `1` in the resulting "array". And the first field from auto-split is `$1` not `$0` , while `perl -a` will put it into `$F[0]` Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

Awk has implicitly numbered arrays like ARGV

And ARGV[1] corresponds to $ARGV[0] in Perl

Similarly will awk's split() index the first element with 1 in the resulting "array".

And the first field from auto-split is $1 not $0 , while perl -a will put it into $F[0]
