Linux Commands for DevOps & Cloud Engineers - Beginner's

Discover what Linux is and how the root file system organizes into a tree, with key directories like /bin, /home, /var, /root, /dev, and /proc, plus basic terminal navigation.

Navigate the linux terminal like a pro using pwd, ls, and cd to move through directories, view hidden files with ls -la, and use tab completion and tilde shortcuts.

Boost productivity in the terminal by using keyboard shortcuts like Ctrl-C to stop a running command, Ctrl-L to clear the screen, and Tab autocomplete for files, folders, and commands.

Learn to create files and folders using touch and mkdir, including multiple files and nested directories with -p, verify results with ls, and understand how touch updates file timestamps.

Delete files safely with rm -i, and verify with ls. Remove directories with rm -r or rmdir (empty only); for non-empty folders use rm -rf, but never run as root.

Master Linux file copying with the cp command, including recursive folder copies (-R), backup essentials, and overwrite prompts (-i) for safer deployments.

Learn how to move and rename files and folders in Linux using the mv command, including overwrite behavior and combining move and rename in a single command.

Explore viewing file content in the Linux terminal with cat, more, less, head, and tail, including real-time tail -f for log monitoring and basic file creation with echo.

Learn to create and edit configuration files on linux using vim and nano, including insert mode, saving with vim commands, and nano shortcuts.

Identify the current user and verify permissions with whoami and id to understand sudo access. Learn how user IDs and groups like ubuntu and sudo enable root privileges.

Master sudo and root access in Linux to manage users and permissions for cloud and devops tasks, including granting sudo privileges and switching users via the sudoers file.

Decode linux file permissions with ls -l and apply chmod, chown, and umask to manage owner, group, and others, and understand defaults like 666/777 and 0022 or 0002.

Learn how to manage Linux user groups and access control by checking groups, creating users and groups, adding users to groups, and securing folders with chown and chmod 770.

Learn to install software on Ubuntu using apt, apt-get, and dpkg; compare their differences and practice installing, removing, and purging packages in an EC2 environment.

Learn how to check if nginx is installed on your system using apt, dpkg, and which. Verify the running status with systemctl and uninstall with apt remove nginx.

Boost your DevOps workflow by mastering essential Linux shell utilities like pwd, date, cal, history, grep, find, cat, and awk for logs and debugging.

Explore essential linux networking commands for devops and cloud engineers, including ping, traceroute, hostname, ip a, nslookup, and dig, to diagnose connectivity and dns issues.

Download files with wget or curl, save outputs, then inspect ports with netstat or ss to verify server availability and service status.

Monitor your linux servers and ec2 instances by using top, htop, df, du, and free to track cpu, memory, disk space, and process activity in real time.

Learn to compress and archive files using tar, gzip, and zip, including creating and extracting archives of logs, backups, and configuration files, and verify sizes on a remote server.
