Block 1 Lab 1 — Finding What You Need, Fast

Scenario

You've just SSH'd into rhel-prod-01 — a server you don't manage day-to-day. The on-call alert says the httpd service is failing. You have no runbook. You need to find the config file, recent logs, and anything that's changed in the last hour. This lab is that workflow.

Objectives

#	Objective
1	Orient yourself — understand where you are and what's on the server
2	Find the httpd config file using find and locate
3	Identify recently changed files (last 60 minutes)
4	Search for error patterns in log files with grep
5	List large files consuming disk space in /var
6	Knowledge check — filesystem triage concepts

Supported Commands

Command	Purpose
pwd	Print working directory
whoami	Current user
hostname	Server hostname
ls [-la] [-lt] [path]	List files; -l long, -a hidden, -t sort by time
find <path> [options]	Find files: -name, -type, -mmin, -size, -user
locate <pattern>	Fast filename search via database
grep [-r] [-i] [-l] <pattern> <path>	Search file contents
du -sh <path>	Disk usage summary of a directory
cat <file>	Print file contents
head / tail [-n] <file>	First/last N lines of a file
