Bash Read Array From Config File

I was recently needing to read values from a configuration file into bash and had some success with reading json with jq into bash array(s). However I resorted to a non json version which worked well. Something like this.

Config File

1
$cat array-simple.cfg
2
[bucket1]
3
name=bucket name 1
4
exclude=folder1 folder 2
5

6
[bucket2]
7
name=bucket name 2
8
exclude=folder5

Code

1
$ cat array-simple.sh
2
#!/bin/bash
3
while read line; do
4
    if [[ $line =~ ^"["(.+)"]"$ ]]; then
5
        arrname=${BASH_REMATCH[1]}
6
        declare -A $arrname
7
    elif [[ $line =~ ^([_[:alpha:]][_[:alnum:]]*)"="(.*) ]]; then
8
        declare ${arrname}[${BASH_REMATCH[1]}]="${BASH_REMATCH[2]}"
9
    fi
10
done < array-simple.cfg
11

12
echo ${bucket1[name]}
13
echo ${bucket1[exclude]}
14

15
echo ${bucket2[name]}
16
echo ${bucket2[exclude]}
17

18
for i in "${!bucket1[@]}"; do echo "$i => ${bucket1[$i]}"; done
19

20
for i in "${!bucket2[@]}"; do echo "$i => ${bucket2[$i]}"; done

Run

1
$ ./array-simple.sh
2
bucket name 1
3
folder1 folder 2
4
bucket name 2
5
folder5
6
exclude => folder1 folder 2
7
name => bucket name 1
8
exclude => folder5
9
name => bucket name 2
