TechTip: Trees Are Good for Climbing and More

Aaron Bartell

The “tree” command can quickly show you the structure of an IFS directory, but it’s not installed in PASE by default. Learn how to get it.

Written by Aaron Bartell

My days are in large part spent in the PASE environment on IBM i.

Originally started by Microsoft, the Open Data Protocol (OData) was devised in part as a means of having a standard input and output so that REST APIs based on OData would be consistent in their implementation.
