NAME

pttree - prints a quick overview of the contents of PyTables HDF5 files.

SYNOPSIS

pttree [ OPTIONS ] filename[:nodepath]

DESCRIPTION

pttree is designed to give a quick overview of the contents of a PyTables HDF5 file by printing a depth-indented list of nodes, similar to the output of the Unix ‘tree‘ function. It can also display the size, shape and compression states of individual nodes, as well as summary information for the whole file. For a more verbose output (including metadata), see ‘ptdump‘.

-L MAX_DEPTH, --max-level MAX_DEPTH

--print-size

--no-print-size
--print-shape

print shape of each node

--no-print-shape
--print-compression

print compression library(level) for each compressed node

--no-print-compression
--print-percent

print size of each node as a % of the total tree size on disk

--no-print-percent
--use-si-units
