Hi folks,
I am sure this has been asked quite some times, but I did not find
anything inspiring or helpful - in fact not too much at all.
For accelerating a script I need the possibility to set up an unknown
number of arrays and to name them (at least partly) with values of a
variable. It is like defining arrays with names that contain an
increasing number: array$x.
While poking around I found out: This does not work at all, even with
simple variables it does not.
dings=bums
echo $dings
bums
ac=12 dings$ac=wasannersder
-bash: dings12=wasannersder: command not found
I looked very deeply into man bash and any manual and howto I found, but
did not find out any reason why this does not work. It must be one of
the basic principles of expansion and assignment, but I would like to
understand it.
And then the question of multi-dimensional arrays (see above). The
"Advanced Bash Scripting Guide" mentions that it is possible to have
them using indirect referencing - but I did not understand how this
could be done.
Any idea, hint or help? It would be a great relief after two days of
search and research.
Dirk
