Companies manually manage Linux users, permissions, and ownership on servers. One wrong chmod or missing chown causes security breaches. This project automates and simulates real enterprise Linux server administration.
- OS: Ubuntu Linux
- Language: Bash
- Tools: useradd, chmod, chown, ps, df, free
- Version Control: Git + GitHub
