我的 ~/bin 中的所有脚本都以“#!/bin/sh”作为第一行，但如果没有 sh，这些脚本将无法运行。当我将所有个人数据转移到 ntfs 分区并在主目录中创建指向它们的符号链接后，出现了此问题。我想我已经在所有受影响的文件夹中正确设置了权限（774 到 bin 中的目录和文件，664 到所有其他文件），并将此条目添加到 /etc/fstab 中：
UUID=5BE8B8E020325D09 /mnt/DATA ntfs-3g auto,users,permissions 0 0
问题就是这样的：
saga@terminal:~$ syncit a b
bash: /home/saga/bin/syncit: Permission denied
saga@terminal:~$ sh ~/bin/syncit a b
<works correctly>
知道这里发生了什么吗？
ls -l 的输出：
对于 /mnt/DATA/bin/：

我将数据移至 sda10
答案1
/mnt/DATA装有noexec旗帜。作为快速修复，/mnt/DATA无需重新安装noexec，即
mount -o remount,exec /mnt/DATA
为了持久性，请修改相应的条目，/etc/fstab以便默认情况下不设置此标志。
