当使用./script执行脚本时，我会看到local：-n：无效选项
我的测试脚本：cat script个

# !/bin/bash
declare -Ax BINS_TO_ARCH_FILE=(
 ["file1"]="test/file1"
 ["file2"]="test/file2"
 ["file3"]="test/file3"
);
function archive-bz2()
{
  local -n DO_NOT_USE_THIS_NAME="$1";
  for path_to_archive in "${!DO_NOT_USE_THIS_NAME[@]}"; do
    echo "path_to_archive: $path_to_archive";
  done
}
archive-bz2 BINS_TO_ARCH_FILE

但是当我在一个带有

bash script

它正在工作...

echo $SHELL
/bin/bash
bash --version

我也用旧的bash版本测试了它，两种方式都工作得很好：（在两种方式上，local都是build in命令

type local
local is a shell builtin
