Download
All commands in this section use the Linux operating system as an example to describe how to download files.
Assume that bucket bucket-test contains the following objects:
obs://bucket-test/test1.txt obs://bucket-test/test2.txt obs://bucket-test/test3.txt obs://bucket-test/test4.txt obs://bucket-test/test5.txt obs://bucket-test/test6.txt obs://bucket-test/src1/ obs://bucket-test/src1/test7.txt obs://bucket-test/src2/ obs://bucket-test/src2/test8.txt obs://bucket-test/src2/src3/ obs://bucket-test/src2/src3/test9.txt
Based on the structure of objects in the bucket, different download scenarios require different commands.
- To download the test1.txt file from the bucket-test bucket to the local src1 folder, use the following command:
./obsutil cp obs://bucket-test/test1.txt /src1
After the download is complete, the following file is generated on the local PC:
└── src1 └── test1.txt
- To download the test1.txt file from the bucket-test bucket to your local PC, use the following command. If test.txt does not exist locally, the test1.txt file will be downloaded and saved as test.txt. If test.txt already exists, the download will overwrite it with the contents of test1.txt.
./obsutil cp obs://bucket-test/test1.txt /test.txt
After the download is complete, the following file is generated on the local PC:
└── test.txt - To recursively download the entire src2 folder from the bucket-test bucket to the local src1 folder in force mode, use the following command:
./obsutil cp obs://bucket-test/src2 /src1 -r -f
After the download is complete, the following files are generated on the local PC:
└── src1 └── src2 ├── src3 └── test9.txt └── test8.txt
- To recursively download all files and subfolders from the src2 folder of the bucket-test bucket to the local src1 folder in force mode, use the following command:
./obsutil cp obs://bucket-test/src2 /src1 -r -f -flat
After the download is complete, the following files are generated on the local PC:
└── src1 ├── src3 └── test9.txt └── test8.txt
- To recursively download all objects from the bucket-test bucket to the local src0 folder in force mode, use the following command:
./obsutil cp obs://bucket-test /src0 -r -f
After the download is complete, the following files are generated on the local PC:
└── src0 ├── test1.txt ├── test2.txt ├── test3.txt ├── test4.txt ├── test5.txt ├── test6.txt ├── src1 └── test7.txt └── src2 ├── src3 └── test9.txt └── test8.txt
- To exclude the src2 folder (including all of its contents) when downloading the src1 folder from the bucket-test bucket, use the following command:
./obsutil cp obs://bucket-test/src1/ src1 -exclude "*src1/src2*" -r -f -mf
Four objects are successfully downloaded, and the download information contains exclude and the specific content.
./obsutil cp obs://bucket-test/src1/ src1 -exclude "*src1/src2*" -r -f -mf Parallel: 5 Jobs: 5 Threshold: 50.00MB PartSize: auto VerifyLength: false VerifyMd5: false Exclude: *src1/src2* Include: CheckpointDir: xxxx OutputDir: xxxx TempFileDir: xxxx [====================================================] 100.00% tps:87.78 ?/s 4/4 2.39KB/2.39KB 223ms Succeed count: 4 Failed count: 0 Succeed bytes: 2.39KB Metrics [max cost:147 ms, min cost:77 ms, average cost:56.00 ms, average tps:8.85, transferred size:2.39KB]
After the download is complete, the following files are generated on the local PC:
└── src1 ├── src3 └── test9.txt └── test7.txt
