The best Linux terminal commands: A practical guide for developers and system administrators

As a developer, system administrator, or tech enthusiast, mastering the Linux terminal is an essential skill. The terminal offers powerful tools and commands that help you work efficiently, automate scripts, and perform complex tasks. In this article, we discuss the best Linux terminal commands that you can use daily to optimize your workflow.

Why the Linux terminal is important

The Linux terminal is an essential part of every Linux distribution. It provides a text-based interface to execute commands, manage files, monitor processes, and more. Unlike graphical user interfaces (GUIs), the terminal is often faster and more flexible, especially for automated tasks and scripts. By learning the best Linux terminal commands, you can significantly increase your productivity.

Basic Linux terminal commands

Let's start with some basic commands that every user should know:

• ls - List all files and folders in the current directory.
• cd - Change the current directory. For example, use cd /var/www to navigate to the /var/www folder.
• pwd - Print the current directory.
• mkdir - Create a new folder. For example, mkdir project creates a folder named "project".
• rm - Delete a file or folder. Use rm -r for recursively deleting folders.
• cp - Copy a file or folder. For example, cp file.txt /backup/ copies file.txt to the /backup folder.
• mv - Move or rename a file or folder. Use mv file.txt newfile.txt to rename a file.
• cat - Display the contents of a file. For example, use cat file.txt.
• less - View a file page by page. Useful for large files.
• grep - Search for text in a file. For example, grep "searchterm" file.txt.
• find - Search for files and folders at a specific location. Use find /path/to/search -name "*.txt" to find all .txt files.
• which - Show the path to an executable file. For example, which python.
• whereis - Locate the binary, source code, or man page of a command.

Advanced Linux terminal commands

In addition to the basic commands, there are also some advanced commands that complete your toolkit:

• chmod - Change the access permissions of a file or folder. For example, chmod 755 script.sh gives execution permissions to the script.
• chown - Change the owner of a file or folder. Use chown user:group file.txt to change the owner and group.
• tar - Archive files. For example, tar -czvf archive.tar.gz /path/to/files creates a compressed tar archive.
• rsync - Synchronize files between directories or servers. For example, use rsync -avz /source/ /destination/.
• ssh - Establish a secure connection to a remote server. For example, ssh user@host.
• scp - Copy files between local and remote systems. Use scp file.txt user@host:/path/.
• tmux - Keep sessions active, even if your connection is interrupted. Start a new session with tmux new -s sessionname.

Useful tools for faster commands

There are various tools and utilities that can help you work faster and more efficiently with the terminal:

• oneliner: A tool that helps you generate shell commands from plain text. Useful for beginners who want to learn quickly. More information: github.com/dorochadev/oneliner.
• cheatshh: A CLI cheatsheet that lets you quickly copy commands to your clipboard. More information: github.com/AnirudhG07/cheatshh.
• bash: The Bourne-Again SHell is the standard shell on most Linux distributions. More information: gnu.org/software/bash.
• bun exec: A runtime to execute shell commands or script files. More information: bun.com/docs/runtime/shell.

Practical tips for using the Linux terminal

Here are some tips to get the most out of the Linux terminal:

• Use tab completion to automatically complete commands and file paths.
• Make use of aliases to shorten frequently used commands. For example, alias ll='ls -la'.
• Combine commands with && to run them sequentially. For example, cd /var/www && ls.
• Learn how to run processes in the background with & and how to manage them with jobs, fg, and bg.
• Use history to view and reuse previous commands.

Conclusion

The Linux terminal is a powerful tool that you shouldn't miss as a developer, system administrator, or tech enthusiast. By learning and applying the best Linux terminal commands , you can significantly improve your workflow. Start with the basic commands and gradually work your way up to advanced techniques. Use tools such as oneliner and cheatshh to speed up learning and make your terminal experience even more efficient.
