/usr/bin/ptdump

Jupyter all-spark-notebook image content combining the upstream jupyter/docker-stacks layer chain (base-notebook, minimal-notebook, scipy-notebook, pyspark-notebook, all-spark-notebook) into a single APK with the scientific Python stack, Apache Spark, R, and Spark/R kernels on top of jupyter-base-notebook.

From jupyter-all-spark-notebook 7.6.1_git20261106-r0 (enterprise-packages), captured 2026-11-08 by running ptdump --help (exit 0). permalink

usage: ptdump [-h] [-v] [-d] [-a] [-s] [-c] [-i] [-R RANGE] filename[:nodepath]

The ptdump utility allows you look into the contents of your PyTables files. It lets you see not
only the data but also the metadata (that is, the *structure* and additional information in the
form of *attributes*).

positional arguments:
  filename[:nodepath]   name of the HDF5 file to dump

options:
  -h, --help            show this help message and exit
  -v, --verbose         dump more metainformation on nodes
  -d, --dump            dump data information on leaves
  -a, --showattrs       show attributes in nodes (only useful when -v or -d are active)
  -s, --sort            sort output by node name
  -c, --colinfo         show info of columns in tables (only useful when -v or -d are active)
  -i, --idxinfo         show info of indexed columns (only useful when -v or -d are active)
  -R RANGE, --range RANGE
                        select a RANGE of rows (in the form 'start,stop,step') during the copy of
                        *all* the leaves. Default values are 'None, None, 1', which means a copy
                        of all the rows.
