EXAMPLES:
|
||
1. Create a bucket on Amazon S3 cloud storage.
|
||
$ mc {{.Name}} s3/mynewbucket
|
||
|
||
2. Create a new bucket on Google Cloud Storage.
|
||
$ mc {{.Name}} gcs/miniocloud
|
||
|
||
4. Create a new bucket on Amazon S3 cloud storage in region ‘us-west-2’.
|
||
$ mc {{.Name}} --region=us-west-2 s3/myregionbucket
|
||
|
||
5. Create a new directory including its missing parents (equivalent to ‘mkdir -p’).
|
||
$ mc {{.Name}} /tmp/this/new/dir1
|
||
|
||
6. Create multiple directories including its missing parents (behavior similar to ‘mkdir -p’).
|
||
$ mc {{.Name}} /mnt/sdb/mydisk /mnt/sdc/mydisk /mnt/sdd/mydisk
