Course overview

Uplatz offers this comprehensive training on Linux Utilities. This is video-based online course (self-paced training). You will be awarded Course Completion Certificate at the end of the course.

Linux utilities are a collection of command-line tools and programs that help users perform system administration, file management, process control, networking, and troubleshooting tasks efficiently. These utilities are fundamental to the Linux operating system and allow users to interact with the system through the terminal or shell.

Linux utilities are essential tools that help users manage files, processes, networks, security, and performance in a Linux environment. Whether for personal use, system administration, or software development, mastering these utilities improves productivity, efficiency, and system reliability.

Linux utilities work by executing commands in the terminal, allowing users to manage files, processes, networks, users, and system configurations. These utilities operate through:

• Command-Line Interface (CLI): Users input commands to perform specific tasks.
• Pipelines and Redirection: Commands can be combined using pipes (|) and redirection (>, <) to manipulate output and input.
• Scripting and Automation: Many utilities can be scripted to automate tasks.
• Permissions and Ownership: Commands interact with files and processes based on user privileges and security settings.

• ls – Lists directory contents.
• cp – Copies files and directories.
• mv – Moves or renames files.
• rm – Deletes files or directories.
• find – Searches for files in a directory hierarchy.

• ps – Displays active processes.
• top / htop – Monitors system performance and running processes.
• kill – Terminates processes.
• nice / renice – Adjusts process priorities.

• whoami – Displays the current user.
• id – Shows user ID and group ID information.
• passwd – Changes user passwords.
• useradd / usermod / userdel – Manages user accounts.

• df – Displays disk space usage.
• du – Shows directory size.
• mount / umount – Mounts and unmounts storage devices.
• fdisk / parted – Manages disk partitions.

• ping – Checks network connectivity.
• netstat / ss – Displays network connections.
• wget / curl – Downloads files from the internet.
• ifconfig / ip – Configures network interfaces.

• uptime – Shows system running time.
• vmstat – Monitors system performance.
• iostat – Displays CPU and disk I/O usage.
• free – Shows memory usage.

• cat – Displays file content.
• grep – Searches for patterns in text.
• sed – Stream editor for modifying text.
• awk – Pattern scanning and text processing.

• chmod – Changes file permissions.
• chown – Modifies file ownership.
• sudo – Executes commands with elevated privileges.
• iptables / firewalld – Configures firewall rules.

• tar – Archives files.
• zip / unzip – Compresses and extracts files.
• rsync – Synchronizes files and directories.
• dd – Copies and converts raw data.

• Efficiency: Command-line utilities allow fast execution of tasks without GUI overhead.
• Automation: Many utilities support scripting, reducing manual work.
• Customization: Users can combine multiple commands to create customized workflows.
• System Stability: Tools help monitor and optimize system performance.
• Security: Utilities provide robust access control, encryption, and network security features.
• Resource Optimization: Tools help manage CPU, memory, and disk usage efficiently.
• Flexibility: Available across different Linux distributions with open-source adaptability.
