Linux Terminal CLI, FHS Navigation & File Operations
Navigate the FHS directory tree (/etc, /var, /home, /usr), manage files with ls, cd, cp, mv, rm, and search with grep and find.
Learning Objectives & Filesystem Hierarchy Standard
### Learning Objectives
- Understand the Linux Filesystem Hierarchy Standard (FHS).
- Search and inspect files efficiently using `grep`, `find`, and `awk`.
- Pipe standard output (`stdout`) and errors (`stderr`) using I/O redirection (`>`, `>>`, `2>`, `|`).
---
### Filesystem Hierarchy Standard (FHS)
Linux organizes files in a unified tree starting at the root directory (`/`):
- `/etc`: System-wide configuration files (`sshd_config`, `passwd`).
- `/var`: Variable state data and log files (`/var/log/syslog`).
- `/home`: Personal user home directories.
- `/bin` / `/sbin`: Essential user and system binaries (`ls`, `ip`, `systemctl`).
