"""Format-agnostic ``nm``-style symbol lister.
|
|
|
|
Prints every symbol found in a binary. For PE files, it prints the
|
|
entries of the *symbol section*; for ELF files, both the static
|
|
(``.symtab``) and dynamic (``.dynsym``) symbols; for Mach-O the
|
|
global symbol table.
|
|
|
|
Example:
|
|
|
|
$ python nm.py /usr/bin/ls
