All commands in this section use the Linux operating system as an example to describe how to perform synchronous upload operations.

Assume that a local folder is in the following structure:

└── src1
    ├── src2
        ├── test1.txt
        └── test2.txt
    ├── src3
    └── test3.txt

Assume that bucket bucket-test contains the following objects:

obs://bucket-test/src1/
obs://bucket-test/src1/src2/
obs://bucket-test/src1/src2/test1.txt
obs://bucket-test/src1/src3/

Based on the structure of the preceding local folder and objects in the bucket, different synchronous upload scenarios require different commands.

To synchronize the test3.txt file in the local src1 folder to the root directory of bucket bucket-test, the command is as follows:
```
./obsutil sync /src1/test3.txt  obs://bucket-test
```
After the synchronization is successful, the test3.txt file is directly uploaded to the bucket because there is no test3.txt in bucket bucket-test. Then, objects in the bucket are as follows:
```
obs://bucket-test/test3.txt
obs://bucket-test/src1/
obs://bucket-test/src1/src2/
obs://bucket-test/src1/src2/test1.txt
obs://bucket-test/src1/src3/
```

To synchronize all files and subfolders in the local src1 folder to the src1 folder in bucket bucket-test, the command is as follows:

./obsutil sync /src1  obs://bucket-test/src1

After the synchronization, the objects in the bucket are as follows:

obs://bucket-test/src1/
obs://bucket-test/src1/test3.txt
obs://bucket-test/src1/src2/
obs://bucket-test/src1/src2/test1.txt
obs://bucket-test/src1/src2/test2.txt
obs://bucket-test/src1/src3/
