Improved version of @robinst

read_properties()
{
  file="$1"
  while IFS="=" read -r key value; do
    case "$key" in
      '#'*) ;;
      *)
        eval "$key=\"$value\""
    esac
  done < "$file"
}

Changes:

• Dynamic key mapping instead of static
• Supports (skips) comment lines

A nice one is also the solution of @kurumi, but it isn't supported in busybox

And here a completely different variant:

eval "`sed -r -e "s/'/'\\"'\\"'/g" -e "s/^(.+)=(.+)\$/\1='\2'/" $filename`"

(i tried to do best with escaping, but I'm not sure if that's enough)
