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`).
