Requirements

Your system must have Python 3.6.x or greater installed, and boto3 if accessing S3 resources such as acacia or aws.

Note
A prepackaged python executable for pshell is available from here.

Running

From the command line, you can start pshell as follows:

Code Block
python3 pshell

Remotes

pshell maintains a list of registered remote servers and the current connection state. The active remote is shown in the left part of pshell's command prompt:

Code Block
portal:> remote portal [ not connected ] * public [ not connected ] aws [ not connected ]

You can query the configuration of a particular remote as follows:

Code Block
portal:/>remote portal --info name = portal type = mflux protocol = https server = data.pawsey.org.au port = 443 domain = ivec

New remotes can be added for an additional Mediaflux server (similar to the default portal and public) or for an S3 resource. For further information, see: pshell and S3 remotes.

Logging in

Authenticate to a remote using the appropriate credentials. In the case of the data portal it will be your Pawsey credentials. In the case of an S3 resource it will be your key and secret pair. If the login was successful, the connection status of the remote will be updated.

Code Block
portal:>login Username: sean Password: portal:/>remote portal [ authenticated ] * public [ not connected ] aws [ not connected ]

You can now navigate (cd, ls) and transfer files (put, get) between your local filesystem and your remote storage resource.

Command syntax

The command line client implements a subset of the standard SFTP commands.

Remote filesystem commands: cd, ls, pwd, mkdir, rmdir

Local filesystem commands: lcd, lls, lpwd

Transfer commands: get, put
