For Internal Xerox Use Only

1. Usage

PigsInSpace {count ← 10} {-n count | -v volume | -c | -l | -r }*

Print the largest 'count' files on the 'volume'. The volume must be a Cedar volume.

The full file name is printed with its file size in pages.

The 'c' switch means don't list cached file

The 'l' switch means don't list local files

The 'r' switch means don't list root files

2. Discussion

An enumeration is done, and the largest FS files found are printed. ``Root files'' that have a FS name (i. e., the FS BTree, checkpoint and VAM) are enumerated twice: once as a root file and once as an FS file. The enumeration is moderately slow: 2-5 minutes on a full sized T-80 disk partition on a Dorado is normal. This is because the program has to open up every file in the cache to find its size. The machine is somewhat sluggish during this command.
