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

Assume that a local folder is in the following structure:

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

Based on the preceding folder structure, different upload scenarios require different commands.

To upload the test3.txt file in the local src1 folder to the root directory of bucket bucket-test, the command is as follows:
```
./obsutil cp /src1/test3.txt  obs://bucket-test
```
After the upload completes, the following object is generated in the bucket:
```
./obs://bucket-test/test3.txt
```
To upload the test3.txt file in the local src1 folder to the root directory of bucket bucket-test and rename it to aaa.txt, the command is as follows:
```
./obsutil cp /src1/test3.txt  obs://bucket-test/aaa.txt
```
After the upload completes, the following object is generated in the bucket:
```
./obs://bucket-test/aaa.txt
```
To upload the test3.txt file in the local src1 folder to the src folder in bucket bucket-test, the command is as follows:
```
./obsutil cp /src1/test3.txt  obs://bucket-test/src/
```
After the upload completes, the following object is generated in the bucket:
```
./obs://bucket-test/src/test3.txt
```
To recursively upload the entire local src2 folder to the root directory of bucket bucket-test in force mode, the command is as follows:
```
./obsutil cp /src1/src2  obs://bucket-test -r -f
```
After the upload completes, the following objects are generated in the bucket:
```
obs://bucket-test/src2/
obs://bucket-test/src2/test1.txt
obs://bucket-test/src2/test2.txt
```

To recursively upload the entire local src1 folder to the src folder in bucket bucket-test in force mode, the command is as follows:

./obsutil cp /src1  obs://bucket-test/src -r -f

After the upload completes, the following objects are generated in the bucket:

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

To recursively upload the all files and subfolders in the local src1 folder to the src folder in bucket bucket-test in force mode, the command is as follows:

./obsutil cp /src1  obs://bucket-test/src -r -f -flat

After the upload completes, the following objects are generated in the bucket:

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

To upload the file1 file to the bucket-test bucket, and resume the upload if the upload fails, run the following commands:

./obsutil cp /file1  obs://bucket-test/file -f

The upload fails. The command output is as follows:

./obsutil cp /file1 obs://bucket-test/file -f

Run the preceding command again to resume the upload. The command output is as follows:

obsutil cp /file1 obs://bucket-test/file -f

To incrementally upload all files from the local src1 folder to the src directory of bucket bucket-test, the command is as follows:

./obsutil cp /src1  obs://bucket-test/src -f -r -u

Four objects are successfully uploaded, one of which is a new object. The command output contains Skip count.

./obsutil cp /src1 obs://bucket-test/src -f -r -u

Run the following command to exclude the src2 folder (including all files and folders contained) when uploading the src1 folder:

./obsutil cp /src1  obs://bucket-test/src -exclude "*src1/src2*" -f -r -mf

Five objects are successfully uploaded, and the upload information contains exclude and the specific content.

./obsutil cp /src1  obs://bucket-test/src -exclude "*src1/src2*" -f -r -mf

After the upload completes, the following objects are generated in the bucket:

obs://bucket-test/src/src1/
obs://bucket-test/src/src1/src3/
obs://bucket-test/src/src1/test3.txt

Resumable upload is available only for large files. Specifically, the file size is greater than 5 GB or the file size is greater than the threshold (50 MB by default).
