In Unix, resources have names. They are visible
in a name space,
organized
into directories. The names can be enumerated by opening and reading a
directory. Information about them can be determined with stat. Their
contents can be read by open and read. They can be changed with open and
write.
And if each resource has a directory (possibly organized in a
multiple-level hierarchy) containing several files that describe
attributes of that resource, what are you to do when you want to print a
report listing a summary of some information about those resources, one
per line?
