# Create bucket

1gsutil mb -p codes-20180829 -c standard -l us-central1 -b ON --pap enforced gs://sushanth-cs-test

# List bucket

Note : This is a Class A operation

1gsutil ls -r -l gs://sushanth-cs-test/**

# Copying from local to bucket

Below command initiates a parallel upload via rsync and recursively uploads all folder and sub-folders to GCS

1gsutil -m rsync -r -d ./ gs://sushanth-cs-test

Below command initiates a parallel upload excluding the pattern via rsync and recursively uploads all folder and sub-folders to GCS. It excludes node_modules, .git, .cache and Eclipse Java folders

1gsutil -m rsync -r -d -x ".*node_modules.*$|.*\.git.*$|.*\.cache.*$|.*Eclipse Java.*$" ./ gs://sushanth-cs-test/**

If you get Caught non-retryable exception while listing... error like below that because in windows MAX_PATH defaults to 260 characters.

1Caught non-retryable exception while listing file://.\: [WinError 3] The system cannot find the path specified: '.\\3. Java\\Eclipse Java\\eclipse-java-2021-06-R-win32-x86_64\\eclipse\\plugins\\org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_16.0.1.v20210528-1205\\META-INF\\maven\\org.eclipse.justj\\org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64\\pom.properties'
2CommandException: Caught non-retryable exception - aborting rsync

To increase that limit, you have two options,

  1. Update Windows Registry

    1Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled
    2Type: REG_DWORD
    3Value: 1

    Tried this and it works.

  2. Specify UNC Paths. Prefix paths with "\?\". This changes maximum path names to 32,767 characters.

    1\\?\C:\Users\~~~~\Documents

    Did not experiment on this. Good to know there is another option.

# Copying from bucket to local

If you want to download the entire bucket, you can do like this. It will create a folder with the buckets name in the current folder.

1-- Parallel and Recursive flags are mentioned in below command
2gsutil -m cp -r gs://sushanth-cs-test ./

If you want to download to a specific folder, that folder needs to exist in target. Here i have created a new folder called t1

1-- Parallel and Recursive flags are mentioned in below command
2gsutil -m cp -r gs://sushanth-cs-test ./t1
