Lesson 6 - Chapter 4: Linux Basics Flashcards
What is one of the most popular GUIs for Ubuntu Linux called?
Unity
What’s the basic file system for virtually all Linux distros?
Extended file system (ext)
What are the 2 most commonly used file systems for Linux?
- ext3
- ext4
(both are 64-bit file systems with journaling support)
How is ext4 better than ext3? (4)
- speed
- max file size
- max partition size
- allowed
- Faster, more efficient
- Larger maximum file size (16 TB vs 2 TB)
- Larger maximum partition size (1 EB vs 32 TB)
- More subdirectories allowed per directory (64,000 vs 32,000)
What’s the main reason you would choose an ext3 file system instead of ext4?
so you can share that ext3 partition with Windows (useful for multiboot system so it’s accessible by Windows)
What’s an ISO file?
an image file for a bootable DVD
After you downloaded an ISO file to create a virtual machine or multi-boot system, what 3 options do you have for installing it?
- Use the virtual machine manager software to attach the ISO as a virtual drive
- If the PC has an optical drive, use a DVD-burning app to burn the ISO file to a blank DVD
- If the PC doesn’t have an optical drive, create a bootable flash drive with a utility using the ISO file
What do you do after the initial steps to create a virtual machine/multi-boot system? (2 ways)
- Virtual machine = Create a new virtual machine with defaults
- Install on physical PC = boot from DVD/USB, install OS on a different partition if the PC already contains an OS
Where do you go to manage startup apps?
a utility called Startup Applications
How do you access the Startup Applications utility to control startup apps?
from the Show Applications screen (click the 9 dots in the lower left corner)
What tool manages Ubuntu’s system updates?
Software Updater
(accessible from Show Applications 9 dot icon)
Where do you go to control how often to check for updates and how they should be handled?
Software Updater > Settings
What is Linux’s command prompt called?
Terminal
What’s the shortcut to open the Terminal?
Ctrl+Alt+T
What is Samba?
Samba is an open-source application that enables systems with different OS on the same LAN to communicate and share files
Does Samba come with most Linux distros?
No you have to download it
Is Samba GUI-based or command-line-based?
Samba is a command-line based app but the Samba Server Configuration Tool GUI is available to help you avoid remembering all the commands
Why is malware rare for Linux desktops particularly Ubuntu? (3)
- the OS is not that popular
- Linux’s user base is more tech-savvy means less security mistakes
- Linux’s file security settings discourage malware being installed/damage from it
Is there anti-malware and anti-virus software available for Linux?
Yes, doesn’t hurt to deploy them to be extra safe
What’s one of the most popular methods of file-level backup for Linux?
the rsync command (short for Remote Sync)
How does the Remote Sync (rsync) backup work? Is it GUI or command-line based? What type of backup does it do?
It’s a command-line operation and uses an incremental backup system that can be automated in scripts
Are there GUI backup utilities available for Linux?
Yes
(Deja Dup, Grsync, Timeshift, Back in Time, UrBackup)
Why is rsync popular with admins?
You can back up to an external drive or another remote system and automate the process with scripting
What’s the max file size for ext4?
16 TB
What’s the max file size for ext3?
2 TB
What’s the maximum partition size for ext4?
1 EB
What’s the maximum partition size for ext3?
32 TB
How many subdirectories are allowed for ext 4 and ext3?
ext4 - 64,000
ext3 - 32,000
Both ext3 and ext4 are compatible with Windows. T or F?
False, only ext3 is compatible with Windows
What does recursive mean? (the -r option) in Linux
It means it takes into consideration all of the directory’s contents
What is the -a option and why is it preferred over the -r recursive option?
On top of being… it also….
(5)
On top of being recursive, it also preserves attributes such as symbolic links, file ownerships, permissions, and modification times
What does the -v option mean?
Verbose, it prints out what you’re doing
