Is it possible to print an array with a * character:
Ex.
echo ${table*[2]}
so that table1[2], table2[2], and table3[2] get printed? I know I cannot make an multidimensional array:
Ex.
table[][]
so I attempting to make multiple one-dimensional arrays.
Ex.
table0[0]
table1[0]
table2[0]
then print...
i=0
j=0
while [[ i < last ]]
do
while [[ j < last ]]
do
print "${table$i[$]}"
j=j+1
done
i=i+1
done
...which errors and declares invalid substitution. I incrementing
