A completely UNIX project from 42. In this project I attempt to recreate the utility software nm.
The objective of this software is to list all symbols contained in binary files, and filter and sort them accordingly to the options passed on arguments.
My version only supports ELF binaries x86 and x86_64.
There is no mandatory options. But, as printing all symbols without ordering nor filtering seemed a little bit like cheating. Therefore I chose to implement the same default comportement as the original nm. Doing so, I used the standard of ELF to read the headers and find the symbol names, values and types.
-a: Displays all symbols, including debugging symbols.-g: Only displays external symbols.-u: Only displays undefined symbols.-r: Sorts the symbols in inverse order.-p: Doesn't sort the symbols at all.
-h: Displays a help message-v: Displays the current version of the project
