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`.

OPTIONS¶

A summary of options is included below.

-L MAX_DEPTH, --max-level MAX_DEPTH

maximum branch depth of tree to display (-1 == no limit)

-S SORT_BY, --sort-by SORT_BY

artificially order nodes, can be either "size", "name" or "none"

--print-size

print size of each node/branch

--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

report sizes in SI units (1 MB == 10^6 B)

--use-binary-units

report sizes in binary units (1 MiB == 2^20 B)

-h
