Introduction
This page is specific to S3 remote types (eg acacia and AWS) it does not apply to the more specialised banksia service. If you need more sophisticated policies and lifecycles, you can use the generated ones shown here as a starting point but will have to use awscli to add any customisations. Please refer to Acacia access and identities and Using policies for more details.
Setup
An acacia project can be added to your list of pshell remotes by using an arbitrary remote name (eg project123) and supplying the access/secret pair after you select the remote and login. An example is given below:After this, the usual file and folder commands will be available.

Info
The info command on a bucket.
Policies
Simple S3 policies can also be automatically created for you, noting that:
...
| Note |

You can use the pshell command "info mybucket" to examine the active policies on that bucket. |

usernames (user1, user2, user3, and user4) readonly access to a project bucket called p0002-sfx.Note: if a user (eg user1) attempts to list buckets they will see nothing. However, if they attempt to list objects inside the bucket it will show the objects inside p0002-sfx/ - see Note 4. | Code Block |

Note: if a user attempts to list buckets they will see nothing. However, if they attempt to list objects inside the bucket it will show the objects inside my-bucket/ - see Note 4. |

Lifecycles
Simple S3 bucket lifecycles can also be automatically created for you affecting multi-part uploads and versioning.
| Note |
|---|
Use the pshell command "info mybucket" to check if there are any current lifecycle rules as you the following may overwrite them with the following examples. |
| Expand |
|---|
|
a basic bucket lifecycle that cleans up failed | enable multi-part and expired version cleanup after 30 days |
|
| Code Block |

pshell> lifecycle my-bucket +mv |
|

|
deletes | delete expired non-current objects after 30 days |
|
. |
| Code Block |

pshell> lifecycle |
mybucket

If versioning is enabled on a bucket, then you will have the option to review and restore deleted objects in the window before the lifecycle cleanup policy permanently removes them. | Panel |

| Code Block |

pshell> lifecycle my-bucket --review

pshell> lifecycle my-bucket/folder1 --restore
Restoring deletions: bucket=my-bucket, prefix=folder1
restoring: folder1/my_file.txt
