bash 脚本中的 chmod 问题

我有一个脚本来格式化驱动器、设置权限 (777)、复制文件、更改权限 (555) 以及卸载和弹出影院 DCP 的驱动器。目前一切正常，但我遇到了 chmod 问题。文件以适当的权限从源驱动器复制到目标驱动器，因此我不确定错误是什么。脚本和输出如下：

脚本

#! /bin/bash

#Format Drive

sudo umount /dev/sda1 
sudo parted -s /dev/sda mktable msdos 
sudo parted /dev/sda mkpart primary ext3 1 100% 
sudo wipefs -a /dev/sda1 
sudo mkfs.ext3 -I 128 -L "DCP" /dev/sda1

#Update /etc/fstab

sudo mount -a

#Mount Drive

sudo mount /dev/sda1 /media/mynamehere/

#Set Permissions

sudo chmod -R 777 /media/mynamehere/DCP

#Copy Files to Target Drive

sudo rsync -av ~/Desktop/Source_Folder/ /media/mynamehere/DCP/

#Set Permissions

sudo chmod -R 555 /media/mynamehere/DCP

#Unmount Disk

sudo umount /dev/sda1

#Eject Disk

sudo eject /dev/sda1

答案1

从你的输出：

chmod: cannot access '/media/mynamehere/DCP': No such file or directory

很简单，该目录DCP只有在您创建它之后才存在（使用下一行中的 rsync）。

由于您以 root 身份运行每个命令，因此chmod 777提前运行应该不会产生任何影响（正如脚本其余部分成功运行的事实所证明的那样）。
