The rise in high-level programming languages in system in network administration has affected the utility of grep and diff when used on files written in these languages. We have observed this problem firsthand in our collaborations with network administrators at Dartmouth Computing and in the electric power industry. We are building context-free grep and hierarchical diff to address the limitations of grep and diff respectively. For both of our tools, we give examples of real-world  problems they could address, sketch their design and evaluation, and describe their impact if built well.
