Hi all,
I'm just a beginer and I got stucked  I'm trying to create multiple
array with variable in array's name. I would expect to have 3 arrays and
each of them would contain 3 elements like array1=(a b c)  array2=(a b c )
array3=(a b c) ; what means that first element of array1[0]="a" and for
example third element of array3[2]="c". This is the way how I do it :

for (( n=1; n<4; n++ ))
do
array$n=(a b c)
done

...but there is syntax error


That's because array$n isn't a valid name. Use eval:

eval "array$n=(a b c)"

create array in loop with variable in array's name

[pikta]

Hi all, 
I'm just a beginer and I got stucked  I'm trying to create multiple
array with variable in array's name. I would expect to have 3 arrays and
each of them would contain 3 elements like array1=(a b c)  array2=(a b c )
array3=(a b c) ; what means that first element of array1[0]="a" and for
example third element of array3[2]="c". This is the way how I do it : 

for (( n=1; n<4; n++ ))
do
array$n=(a b c)
done

...but there is syntax error and I can not fix it. I know I can declare
these 3 arrays as : 
array1=(a b c)
array2=(a b c)
but this is just a simple example; in fact I want to read from several files
to array$n and I can not go through ... can I declare array's name with some
variable in it's name pls help; thanks in advance for any hint
