Re: Any chance of multi-dimensional arrays?

[Eduardo Bustamante]

Hey, calm down. People are just trying to help.

Also, this question has already been asked previously. Please read this:

http://lists.gnu.org/archive/html/bug-bash/2011-09/msg00062.html

(To put you in context, Chet Ramey is the current maintainer of bash).

It's not really an important feature. Bash is already doing too much for a
*shell* language (yes, note that a shell language isn't the same as a
scripting language).

There are a lot of general purpose languages (not shell languages), that
support multi-dimensional arrays. And these languages can call external
tools just fine. Python, Perl, Ruby, ... pick one. Even Awk has faked
support for multi-dimensional arrays.

Don't take me wrong though. Bash is really good, for what it was meant. If
you need complex data structures, or complex text processing, bash isn't
really the best tool for the job.

Just do yourself a favor, and start learning a new language. One that
supports custom data structures. That already has support for
multi-dimensional arrays.


P.S.: If you still have problems understanding the difference between a
shell, and a general purpose language:
