# dlopen-notes(1)

## NAME

dlopen-notes.py

## SYNOPSIS

**dlopen-notes.py** \[-r\] \[-s\] \[-f \[FEATURE1,FEATURE2\]\] \[-h\] filename \[filename ...\]

## DESCRIPTION

Read .note.dlopen notes from ELF files and report the contents.

ELF binaries store link-time dependencies in their headers, which can be parsed by various tools. There is no machine-readable metadata about dependencies loaded at build time via [**dlopen**(3)](/dlopen/3.md) available by default. The ELF Dlopen Metadata specification aims to fill this gap by defining a common format. See https://systemd.io/ELF\_DLOPEN\_METADATA/.

This tool allows parsing such a note, and printing out the result in various formats.
