psstree 0.2.0

list process' PSS sorted descendingly within their parent-child hierarchy. can also do same for disk-space usage

PSS-tree

# python -m psstree --help

usage: __main__.py [-h] [--expand] [--raw] [--du PATH]

gets process' PSS via /proc/<PID>/smaps(_rollup), sorts it descendingly within their parent-child hierarchy, and displays it in an interactive TUI with collapsible sections. alternatively can do the same for disk-space usage given a root-path


options:
  -h, --help  show this help message and exit
  --expand    [TUI only] expand all collapsible sections at start
  --raw       disable TUI and dump formatted repr directly to stdout
  --du PATH   report disk space instead, for given root-path

# python -m psstree --raw
