将文件一个位置复制到另一个位置

Question

以下是shell脚本中提到的代码

SOURCE="/my/folder"
DESTINATION="/my/destination"

cp -r "$SOURCE/subdir/"* "$DESTINATION/another_sub/"

代码给我一个错误

/my/folder: no such a file or directory 

此代码有什么问题。我也直接在终端上检查了文件夹是否可以正常工作，但是使用Shell脚本却无法正常工作

如何在Linux操作系统中将文件从一个源位置复制到另一个目标位置。

按照您的 源 的以下代码和命令，到 目标 位置。

ubuntu@staging-docker:~/copyfile$ ls
copy.sh  destination_dir  source_dir
ubuntu@staging-docker:~/copyfile$ tree
.
├── copy.sh
├── destination_dir
└── source_dir
    └── source_file.txt

2 directories, 2 files

ubuntu@staging-docker:~/copyfile$ cat copy.sh

#!/bin/bash
source_location='/home/ubuntu/copyfile/source_dir/source_file.txt'
Destination_location='/home/ubuntu/copyfile/destination_dir'
`cp -r $source_location $Destination_location`

ubuntu@staging-docker:~/copyfile$ sh copy.sh

ubuntu@staging-docker:~/copyfile$ tree
.
├── copy.sh
├── destination_dir
│   └── source_file.txt
└── source_dir
    └── source_file.txt

2 directories, 3 files
ubuntu@staging-docker:~/copyfile$

ubuntu@staging-docker:~/copyfile$ mkdir source_dir
ubuntu@staging-docker:~/copyfile$ mkdir destination_dir
ubuntu@staging-docker:~/copyfile$ ls
destination_dir  source_dir
ubuntu@staging-docker:~/copyfile$ cat > source_dir/source_file.txt
This is a source file
ubuntu@staging-docker:~/copyfile$ tree
.
├── destination_dir
└── source_dir
    └── source_file.txt

2 directories, 1 file
ubuntu@staging-docker:~/copyfile$ cp source_dir/source_file.txt destination_dir/.
ubuntu@staging-docker:~/copyfile$ tree
.
├── destination_dir
│   └── source_file.txt
└── source_dir
    └── source_file.txt

2 directories, 2 files
ubuntu@staging-docker:~/copyfile$

Answer 2

/my/folder: no such a file or directory 

此错误表明它无法从根/中找到该文件夹​​。

尝试

SOURCE="./my/folder"
DESTINATION="./my/destination"

如果脚本在与文件夹相同的目录中运行。或使用

SOURCE="~/my/folder"
DESTINATION="~/my/destination"

如果文件夹位于用户的主文件夹之外。
