I want to download all bucket files using gsutil in my django non-rel gae app.
gsutil -m cp -R gs://"BUCKET NAME" .
Replace "BUCKET NAME" with the name of your bucket(no quotes) and don't forget the period at the end. If you want to specify a folder replace the period with the destination folder.
-m to perform a parallel (multi-threaded/multi-processing) copy
-R to copy an entire directory tree

I have a google cloud bucket which has 7 subfolders named subset0 to subset7. I want to copy all of them to google colab. Right now I am using code like
!gsutil -m cp -r gs://mybucket/datafolder/subset0 datafolder/
to copy each folder separately. I am not sure how I can write a for loop to copy all folders without repeating the same line 7 times. Thanks a lot!!
As #FerreginaPelona mentioned in the comments, you can use gsutil -m cp -r gs://mybucket/datafolder/subset* datafolder/ if your gs://mybucket/datafolder/ only contains subset0 to subset7 and no other subfolders.
However, if your source bucket path has other subfolders and you only want to specify your needed subfolders, you may put your subfolders in a list and use a for loop as shown below.
from google.colab import auth
auth.authenticate_user()
# Download the file from a given Google Cloud Storage bucket.
subfolder_list = ["subset0","subset1","subset2","subset3","subset4","subset5","subset6","subset7"]
for subfolder in subfolder_list:
!gsutil -m cp -r gs://mybucket/datafolder/{subfolder} /datafolder
I am trying to download a full bucket from my Google Cloud Storage. I am using gsutil and the CLOUD SHELL Terminal.
My current piece of code receives and error: "CommandException: Destination URL must name a directory, bucket, or bucket
subdirectory for the multiple source form of the cp command."
The code is:
gsutil -m cp -r gs://googleBucket D:\GOOGLE BACKUP
where googleBucket is the bucket and D:\GOOGLE BACKUP is the directory to my desired download location. Am I missing something here?
Any help is appreciated.
P.S. I am in no way tech savvy, and most of this is new to me.
download this way first
gsutil -m cp -r gs://googleBucket .
The . downloads it to current directory. Do an ls and you will see the download
Then go to the 3 dots and download locally. The 3 dots is to the right of open editor.
I want to create a folder in GCP bucket with date as suffix:
I am trying this
gsutil mkdir gs://bucket_name/raw/data_"$(date +"%m-%d-%y")"
I also tried this:
dt="$(date +"%m-%d-%y")"
mkdir data_$dt
gsutil cp -r data_$dt gs://bucket_name/raw/
But in this getting error :
CommandException: No URLs matched
is there any other way?
Folders doesn't exist in Cloud Storage. The folder representation on the console is simply a human representation.
All the blobs are stored at the root of the bucket. The file name contain the path (that you name folder) and the effective name. Thus, if you add a file with a path, you see directories. If you remove it, all the directories disappeared.
Because of this, you can't filter on a file pattern, only on the path prefix.
So, the solution if you want to do this is to create a placeholder file
dt="$(date +"%m-%d-%y")"
mkdir data_$dt
touch data_$dt/placeholder
gsutil cp -r data_$dt gs://bucket_name/raw/
I have a problem downloading entire folder in GCP. How should I download the whole bucket? I run this code in GCP Shell Environment:
gsutil -m cp -R gs://my-uniquename-bucket ./C:\Users\Myname\Desktop\Bucket
and I get an error message: "CommandException: Destination URL must name a directory, bucket, or bucket subdirectory for the multiple source form of the cp command. CommandException: 7 files/objects could not be transferred."
Could someone please point out the mistake in the code line?
To download an entire bucket You must install google cloud SDK
then run this command
gsutil -m cp -R gs://project-bucket-name path/to/local
where path/to/local is your path of local storage of your machine
The error lies within the destination URL as specified by the error message.
I run this code in GCP Shell Environment
Remember that you are running the command from the Cloud Shell and not in a local terminal or Windows Command Line. Thus, it is throwing that error because it cannot find the path you specified. If you inspect the Cloud Shell's file system/structure, it resembles more that of a Unix environment in which you can specify the destination like such instead: ~/bucketfiles/. Even a simple gsutil -m cp -R gs://bucket-name.appspot.com ./ will work since Cloud Shell can identify the ./ directory which is the current directory.
A workaround to this issue is to perform the command on your Windows Command Line. You would have to install Google Cloud SDK beforehand.
Alternatively, this can also be done in Cloud Shell, albeit with an extra step:
Download the bucket objects by running gsutil -m cp -R gs://bucket-name ~/ which will download it into the home directory in Cloud Shell
Transfer the files downloaded in the ~/ (home) directory from Cloud Shell to the local machine either through the User Interface or by running gcloud alpha cloud-shell scp
Your destination path is invalid:
./C:\Users\Myname\Desktop\Bucket
Change to:
/Users/Myname/Desktop/Bucket
C: is a reserved device name. You cannot specify reserved device names in a relative path. ./C: is not valid.
There is not a one-button solution for downloading a full bucket to your local machine through the Cloud Shell.
The best option for an environment like yours (only using the Cloud Shell interface, without gcloud installed on your local system), is to follow a series of steps:
Downloading the whole bucket on the Cloud Shell environment
Zip the contents of the bucket
Upload the zipped file
Download the file through the browser
Clean up:
Delete the local files (local in the context of the Cloud Shell)
Delete the zipped bucket file
Unzip the bucket locally
This has the advantage of only having to download a single file on your local machine.
This might seem a lot of steps for a non-developer, but it's actually pretty simple:
First, run this on the Cloud Shell:
mkdir /tmp/bucket-contents/
gsutil -m cp -R gs://my-uniquename-bucket /tmp/bucket-contents/
pushd /tmp/bucket-contents/
zip -r /tmp/zipped-bucket.zip .
popd
gsutil cp /tmp/zipped-bucket.zip gs://my-uniquename-bucket/zipped-bucket.zip
Then, download the zipped file through this link: https://storage.cloud.google.com/my-uniquename-bucket/zipped-bucket.zip
Finally, clean up:
rm -rf /tmp/bucket-contents
rm /tmp/zipped-bucket.zip
gsutil rm gs://my-uniquename-bucket/zipped-bucket.zip
After these steps, you'll have a zipped-bucket.zip file in your local system that you can unzip with the tool of your choice.
Note that this might not work if you have too much data in your bucket and the Cloud Shell environment can't store all the data, but you could repeat the same steps on folders instead of buckets to have a manageable size.
By using gcloud shell I have downloaded all my bucket but i couldn't find the downloaded files.
I used the command
gsutil -m cp -R gs://bucket/* .
P.S. Please don't make -1 on that post if I asked something wrong let me know in comments and I will learn how to ask a question correctly and save your time. Thanks
You used the command gsutil cp, as documented here:
https://cloud.google.com/storage/docs/gsutil/commands/cp
The parameters for this command are:
gsutil cp [OPTION]... src_url dst_url
So you used Option gsutil -m for to perform a parallel (multi-threaded/multi-processing) copy.
Then you also added -R to traverse all directories in your bucket
As "destination URL" you entered a "." which specified the current working directory.
So your files should be located in your home directory, or in any directory where you switched to using the cd command inside your command window.
It would download to the directory you were in when you ran the command. If you never changed the directory using $cd ... command, then it should be at the root. On a Mac, that would be Macintosh > Users > YourName.
