Recalling and using Linux commands effectively is a crucial skill for Linux enthusiasts, sysadmins, and developers. Fortunately, there's a plethora of useful tools to simplify this process and improve your command-line proficiency.

Whether you are an experienced Linux user or just beginning your journey, these five essential tools are here to make your command-line experience smoother and more enjoyable.

1. history

The history command is useful if you want to keep track of your command-line activity. It provides a chronological record of previously executed commands, which makes it easy to review, reuse, and learn from your past interactions with the terminal.

With the history command, you can quickly recall and re-execute complex or frequently used commands. Moreover, it helps you troubleshoot issues by allowing you to identify what went wrong in previous commands.

You can access your Bash command history by simply typing history in the terminal, and a list of your recent commands, each associated with a unique number, will be displayed.

The history command not only boosts productivity but also serves as an excellent learning resource for Linux newcomers. Additionally, by reviewing your command history, you can better understand how various commands work and gradually increase your command-line proficiency.

2. apropos

The apropos command is a powerful Linux tool designed to help you discover relevant commands based on keywords and descriptions. It is specifically used in scenarios when you know what you want to do but cannot quite remember the exact command.

By typing apropos followed by a keyword or phrase related to your task, you will receive a list of commands and manual pages that match your query. This means you can quickly find the right command without going through lengthy documentation or resorting to online searches.

Whether you are a seasoned sysadmin or a Linux enthusiast, apropos is your go-to guide for navigating the rich Linux command ecosystem.

3. cheat

cheat is another practical tool that helps you create and access cheat sheets for Linux commands directly from the terminal. It allows you to create concise, custom cheat sheets according to your requirements.

With the cheat command, you can create, edit, and view cheat sheets and refer to frequently used commands. This tool encourages efficient command memorization, which makes it a valuable asset for Linux users who want to optimize their command-line productivity.

Additionally, cheat enables you to organize your cheat sheets by category or topic, which makes it easy to locate the commands you need.

4. The fish Shell

fish, short for Friendly Interactive Shell, is a modern and user-friendly alternative to traditional Linux shells like Bash. It is renowned for its intuitive tab completions, auto-suggestions, and syntax highlighting.

fish simplifies your command-line experience by offering context-aware suggestions based on your command history. This helps you discover and use commands more efficiently.

Moreover, fish shell's focus on user-friendliness and convenience makes it an essential tool for Linux users who want a more user-centric and interactive command-line experience.

5. hstr

hstr is a Linux utility that transforms your command history into an interactive, searchable interface. It improves upon the standard command history by offering fuzzy search capabilities, which allow you to find and reuse commands with ease.

With hstr, you can quickly locate and execute previously used commands by typing keywords or phrases associated with those commands. This feature is particularly beneficial when you vaguely remember a command but need to pinpoint it within your extensive history.

Furthermore, hstr supports additional features such as history merging, interactive filtering, and history bookmarks, which makes it a versatile tool for managing and recalling command-line interactions.

It's Time to Master Linux Commands

With these useful tools by your side, Linux commands will no longer be a challenge to remember. From revisiting your command history to discovering relevant commands instantly, these tools make the Linux command line an accessible and enjoyable place.
