PachCTL Shell

The HPE Machine Learning Data Management Shell is a special-purpose shell for HPE Machine Learning Data Management that provides auto-suggesting as you type. New HPE Machine Learning Data Management users will find this user-friendly shell especially appealing as it helps to learn pachctl, type commands faster, and displays useful information about the objects you are interacting with. This new shell does not supersede the classic use of pachctl shell in your standard terminal, but is a compelling convenience for power users and beginners alike. If you prefer to use just pachctl, you can continue to do so.

To enter the HPE Machine Learning Data Management Shell, type:

pachctl shell

When you enter pachctl shell, your prompt changes to display your current HPE Machine Learning Data Management context, as well as displays a list of available commands in a drop-down list.

To scroll through the list, press TAB and then use arrows to move up or down. Press SPACE to select a command.

When in the HPE Machine Learning Data Management Shell, you do not need to prepend your commands with pachctl because HPE Machine Learning Data Management does that for you automatically behind the scenes. For example, instead of running pachctl list repo, run list repo:

With nested commands, pachctl shell can do even more. For example, if you type list file <repo>@<branch>/, you can preview and select files from that branch:
