I remember when Linux switched from a. out libraries to elf.

[@HarshKapadia]

@CaribouDataScience oh wow, that's amazing! Thank you for sharing that! How was the transition accepted by the community? Did people already want it? Can you please share some of your experiences around all of it? Thank you!

your machine has objdump but you had a typo. Great work by the way.

Given that an ELF file can have multiple sections, can we represent the section headers as an array of Elf64_Shdr/Elf32_Shdr structures? For example, this is my current mental picture regarding sections and section-headers: Elf64_Shdr Sections[] = { {.sh_name = .bss, .sh_type = ..., .sh_flags = ..., .sh_addr = ..., .sh_offset = ..., .sh_size = ..., .sh_link = ..., .sh_info = ..., .sh_addralign = ..., .sh_entsize = ...}, {.sh_name = .data, .sh_type = ..., .sh_flags = ..., .sh_addr = ..., .sh_offset = ..., .sh_size = ..., .sh_link = ..., .sh_info = ..., .sh_addralign = ..., .sh_entsize = ...}, // Additional sections... }; Is this representation accurate?

@@vaseemakram6692 Yes, you can! I've done something similar: github.com/HarshKapadia2/parse-elf/blob/main/src%2Fpelf.c#L68
