KodeKloud Linux Lab 4 Solution | Linux kernel Modules Boot and Filetypes (Step-by-Step)

Going forward, you will need to make use of sudo for running several privileged commands. Understanding system initialization, systemd targets, file types, Linux directory structure, and hardware detection are essential skills for any Linux system administrator. This lab covers all of these important concepts.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
WHAT YOU WILL LEARN
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

How to identify the init process used by a Linux system
How to check and change systemd targets
How to determine file types using the file command
Which directory is recommended for third-party software installation
Where block device files are stored in Linux
How to identify hardware vendors using lspci

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
LAB TASKS COVERED
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Identify the init process used by the system
Find the default systemd target set in the system
Change the system target to multi-user.target
Determine what type of file firefox.deb is located at /root
Determine what type of file sample_script.sh is located at /root
Identify the recommended directory for installing third-party IDE software
Find which directory contains block device files used by lsblk
Identify the vendor name for the Ethernet Controller in the system

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
COMMAND REFERENCE
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

ps -p 1 .................... Check init process (PID 1)
systemctl get-default ...... Display current default systemd target
systemctl set-default multi-user.target ... Change default target to multi-user
systemctl isolate multi-user.target ...... Switch to multi-user target immediately
file /root/firefox.deb ..... Determine type of .deb file
file /root/sample_script.sh Determine type of shell script file
lsblk ...................... List block devices
ls /dev .................... View block device files
lspci ...................... List all PCI devices
lspci | grep -i ethernet ... Find Ethernet controller information
sudo -i .................... Switch to root user (if needed)

Bob's password for sudo operations: caleston123
Standard users do not possess the ability to execute high-level tasks. Therefore, prepend sudo to commands when needed.
