Question

使用./script执行脚本时，我看到了 local：-n：无效选项

我的测试脚本：cat script

#!/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

的子shell中执行它时

bash script

它正在运作......

echo $SHELL
/bin/bash

我使用较旧的bash版本测试了它，并且两种方式都正常工作:( 在本地都是建立命令

type local
local is a shell builtin
