Bash Array Dynamic Name

Sometimes you want to have dynamic array names to simplify code. Below is one way of making the array name dynamic in a loop.

1
#!/bin/bash
2

3
section1=(
4
 fs-01
5
 fs-02
6
)
7
section2=(
8
 fs-03
9
)
10

11
function snap() {
12
  tag=$1
13
  echo
14
  echo "TAG: $tag"
15
  x=$tag
16
  var=$x[@]
17
  for f in "${!var}"
18
  do
19
    echo "fss: $f"
20
  done
21
}
22

23
snap "section1"
24
snap "section2"

And output like this.

1
TAG: section1
2
fss: fs-01
3
fss: fs-02
4

5
TAG: section2
6
fss: fs-03
