There are a few ways to define an array, at least in Bash, and Ksh.
array=(first_member second_member third_member)
if you do it this way, the members are assigned sequentially, meaning they can be referenced by their index, which in this case starts at "0"
# echo ${array[0]}
first_member
# echo ${array[1]}
second_member
# echo ${array[2]}
third_member
Alternatively, you can assign them like this:
# array[2]="hello there"
Now, check the value of of [2]:
# echo ${array[2]}
hello there
To display all of the members of the array, use "*" or "@"
this can be good for for|while|until loops.
# for member in ${array[*]}; do echo $member;done
first_member
second_member
hello there
