Script to Search /usr/lib Files

README.md

check.py

Given a needed.txt file with required dependencies, search thorough these given directories for them:

• /usr/lib
• /usr/lib32
• /usr/lib64

Following this stackoverflow post:

objdump -p /path/to/binary/here | grep NEEDED | awk '{ print $2 }' > needed.txt

check.py

#!/usr/bin/env python
