Linux Bash script to read samba config

I'm trying to create a bash script that will read the samba config, loop through the different "sections" and act if a variable is set

Here is an example config:

[global]
    workgroup = METRAN
    encrypt passwords = yes
    wins support = yes
    log level = 1 
    max log size = 1000
    read only = no
[homes] 
    browsable = no
    map archive = yes
[printers] 
    path = /var/tmp
    printable = yes
    min print space = 2000
[music]
    browsable = yes
    read only = yes
    path = /usr/local/samba/tmp
[pictures]
    browsable = yes
    read only = yes
    path = /usr/local/samba/tmp
    force user = www-data

Here is kinda what I want to do (I know this syntax a real language, but it should give you the idea:

#!/bin/sh
#
CONFIG='/etc/samba/smb.conf'
sections = magicto $CONFIG    #array of sections
foreach $sections as $sectionname       #loop through the sections
  if $sectionname != ("homes" or "global" or "printers")
    if $force_user is-set
       do something with $sectionname and with $force_user
    endif
    else
       do something with $sectionname
    endelse
  endif
endforeach

Solution

This will read each section and get key,value pair.

#!/bin/bash
CONFIG='/etc/samba/smb.conf'
for i in homes music; do
    echo "$i"
    sed -n '/\['$i'\]/,/\[/{/^\[.*$/!p}' $CONFIG | while read -r line; do
        printf "%-15s : %s\n" "${line%?=*}" "${line#*=?}"
    done
done

Output

homes
browsable  : no
map archive : yes
music
browsable  : yes
read only  : yes
path       : /usr/local/samba/tmp

Explanation

sed -n '/\['$i'\]/,/\[/{/^\[.*$/!p}'

1) /\['$i'\]/,/\[/ Matches the section name between [] until the next [

2) {/^\[.*$/!p} Matches the start of line ^ followed by [ and zero or more characters .* until end of line $ and if matches don't print !p
${line%?=*} Trim string from the end (right) until first = and any char ?
${line#*=?} Trim string from the start (left) until first = and any char ?
