The File System • The root directory • Other partitions
are “mounted” • Things have their places • Names are case-sensitive
/ ├── bin ├── dev ├── etc ├── home │
└── pi ├── lib ├── media ├── opt ├── root ├── tmp ├── usr └── var
Permissions • Essential for Un*x systems • Owner, group, others
• Read, write, execute
