Description
iCommands is a collection of commands for Unix and Windows that are used in the iRODS system to interact with the CyVerse Data Store. Many commands are very similar to Unix utilities. For example, to list files and directories, you use ls in Linux, but in iCommands you use ils.
While iCommands are great for all transfers and for automating tasks via scripts, they are the best choice for large files (2-100 GB each) and for bulk file transfers (many small files). For a comparison of the different methods of uploading and downloading data items, see Downloading and Uploading Data.
Using iCommands with your CyVerse username and password allows you access to all files that have been shared by other users; however, you can download data sets that have been made public without a CyVerse account.
