About iCommands

iCommands are a set of commands for Unix and Windows that are used in the iRODS system. Before you can use iRODS iCommands, you must first install iCommands and configure your environment. If you have already set up your environment, skip this step.

To share data with a user, you must give the user at minimum read permission to the parent directory that contains the file and any other parent folders within the folder hierarchy.

To share files and folders in the DE, see Sharing and Unsharing Data Files and Folders in the DE.

The following table contains some of the more common iCommands:
