Drawbacks in organising and finding files in hierarchies have led researchers to explorenon-hierarchical and search-based filesystems, where file identity and belonging is pred-icated by tagging files to categories. We have implemented a chdir() shell extension en-abling navigation to a directory using a search expression. Our extension is light-weightand avoids modifying the file system to guarantee backwards compatibility for applicationsrelying on normal hierarchical file namespaces.
