All commands in this section use the Linux operating system as an example to describe how to copy files.

Assume that bucket bucket-src contains the following objects:

obs://bucket-src/test1.txt
obs://bucket-src/test2.txt
obs://bucket-src/test3.txt
obs://bucket-src/test4.txt
obs://bucket-src/test5.txt
obs://bucket-src/test6.txt
obs://bucket-src/src1/
obs://bucket-src/src1/test7.txt
obs://bucket-src/src2/
obs://bucket-src/src2/test8.txt
obs://bucket-src/src2/src3/
obs://bucket-src/src2/src3/test9.txt

Based on the structure of objects in the bucket, different copy scenarios require different commands.

To copy the test1.txt file from bucket bucket-src to bucket bucket-dest, the command is as follows:
```
./obsutil cp obs://bucket-src/test1.txt  obs://bucket-dest
```
After the copy is complete, the following object is generated in bucket bucket-dest:
```
obs://bucket-dest/test1.txt
```
To copy the content of the test1.txt file in bucket bucket-src to the text.txt file in bucket bucket-dest, the command is as follows:
```
./obsutil cp obs://bucket-src/test1.txt  obs://bucket-dest/test.txt
```
After the copy is complete, the following object is generated in bucket bucket-dest:
```
obs://bucket-dest/test.txt
```
To copy the test1.txt file in bucket bucket-src to the text folder in bucket bucket-dest, the command is as follows:
```
./obsutil cp obs://bucket-src/test1.txt  obs://bucket-dest/test/
```
After the copy is complete, the following object is generated in bucket bucket-dest:
```
obs://bucket-dest/test/test1.txt
```
Run the following command to recursively copy the entire src2 folder in bucket bucket-src to bucket bucket-dest in force mode:
```
./obsutil cp obs://bucket-src/src2  obs://bucket-dest -r -f
```
After the copy is complete, the following objects are generated in bucket bucket-dest:
```
obs://bucket-dest/src2/
obs://bucket-dest/src2/test8.txt
obs://bucket-dest/src2/src3/
obs://bucket-dest/src2/src3/test9.txt
```
To recursively copy all files and subfolders in the src2 folder in bucket bucket-src to bucket bucket-dest in force mode, the command is as follows:
```
./obsutil cp obs://bucket-src/src2  obs://bucket-dest -r -f -flat
```
After the copy is complete, the following objects are generated in bucket bucket-dest:
```
obs://bucket-dest/test8.txt
obs://bucket-dest/src3/
obs://bucket-dest/src3/test9.txt
```
