bash: assinging array to a dynamic variable

[PryGuy]

Good day, everyone!

I have an array I want to assign to a dynamic variable. If I want to do it for a string - I do:

#!/bin/bash

getVar() {
  eval $1="'$2'"
}

getVar FOO "bar"
echo $FOO
exit 0

But it doesn't work out with arrays... Please help me! Thanks in advance!

you'll probably have to loop through all array items in $2, and assign each item to $1

[PryGuy]

Well, I have this idea also, but how do I call $1 in such case?
The constructs like

с=0
for i in $2; do
  eval ${1[$c]}="'$i'"
  ((c++))
done

do not work...

[PryGuy]

Wow! This worked!

getVar() {
  c=0
  for i in $2; do
    eval $1[$c]="'$i'"
    ((c++))
  done
}

getVar FOO "1 2 3 4 5"
echo ${FOO[1]}
exit 0

declare -a FOO=(1 2 3 4 5)
