# ELF Tool
Small utility that can parse 64bit ELF binaries. Created while reading the fantastic book "Learning Linux Binary Analysis" written by elfmaster.
# Usage
```bash
Usage: elftool [opts]
Opts: -h display this help
-a display the Elf Header, Program Header Table and Section Header Table
-e display the ELF Header
-p display the Program Header Table
-s display the Section Header Table
```
So, for example we can learn about the section header table of /bin/ls:
```bash
cyrill@0x00 ~/elftool > cargo run -- -s /bin/ls
Finished dev [unoptimized + debuginfo] target(s) in 0.01s
Running `target/debug/main -s /bin/ls`
Section Header Table of /bin/ls with 25 entires
