Every Unix journey starts with the basics
Understanding and using Unix is very much like learning a new language. And just like a new language, you first need to grasp the basics. Your first mission — learn what the term “Unix command” means.
A Unix command is a string of characters that the Unix operating system recognizes and interprets to perform a particular task. Typically, a Unix command consists of an operation (command itself), options (modify the behavior of the command), and arguments (data upon which the command acts).
Use this knowledge to bravely walk into the realms of Unix. With your head held high, confidently type your first commands. One step at a time, the crypto-landscape of Unix will start to make sense.
The Need for a Unix Commands Cheat Sheet
A Unix cheat sheet is a god-send when you’re just beginning your Unix journey or need a quick refresher. Even seasoned Unix users might need occasional help remembering commands. Therefore the cheat sheet unix commands becomes a mainstay — it quickly offers the top commands you need to master.
The Cheat Sheet Unix Commands You Can’t Ignore
Let’s get down to our main business. There are plenty of Unix commands, but as a beginner or occasional user, you don’t need all of them. Below are the essential Unix commands you should master.
ls – Lists all the files and directories in your present directory.
cd – Stands for change directory, allowing you to move between different directories.
pwd – ‘Print Working Directory’ displays your current directory.
Feel that? That’s the thrill of understanding Unix bit by bit. Now increase the pace, let’s learn how to manipulate data and files in Unix.
File and Data / Text Manipulation Commands
cat – Combine and display files.
cp – Copy files and directories.
mkdir – Make a new directory.
rm – Remove files and directories.
mv – Move or rename files and directories.
Try to see Unix as an adventure game. Each command unlocks new capabilities and takes you a step further in your journey.

3. set prefix
To set the correct partition containing the Grub modules, use the set prefix command followed by the partition path.
grub rescue> set prefix=(hd0,msdos1)/boot/grub
Replace (hd0,msdos1) with the appropriate partition identifier.
4. set root
Similar to the prefix, you need to set the root partition using the set root command.
grub rescue> set root=(hd0,msdos1)
5. insmod
The insmod command is used to load Grub modules, such as normal and linux. Start by loading the normal module:
grub rescue> insmod normal
6. normal
After loading the normal module, execute the normal command to exit the Grub rescue mode and return to the standard Grub menu.
grub rescue> normal
7. boot
If you’ve manually set up the boot parameters using Grub commands, use the boot command to boot the system.
grub rescue> boot
Remember: You must load the required modules and set the boot parameters correctly before using the boot command.
Example: Fixing a Broken Grub Configuration
Let’s walk through an example of how to fix a broken Grub configuration using Grub rescue commands.
Suppose you have a dual-boot system with Windows and Debian installed. You accidentally deleted the Linux partition, and now, when you turn on your computer, you see the Grub rescue prompt.
Here’s how to fix the issue and boot into Windows:
List the partitions: Use the ls command to list all available partitions.
grub rescue> ls
You may see output like this:
(hd0) (hd0,msdos5) (hd0,msdos2) (hd0,msdos1)
Identify the Windows partition: You need to find the partition containing the Windows boot files. Check each partition using the ls command followed by the partition identifier, like this:
grub rescue> ls (hd0,msdos1)
When you find the partition containing the “Boot” folder, proceed to the next step.
Set the root partition: Set the root partition using the partition identifier found in the previous step.
grub rescue> set root=(hd0,msdos1)
Load the ntldr module: Use the insmod command to load the ntldr module, which is required for booting Windows.
grub rescue> insmod ntldr
Set the boot file: Point Grub to the Windows boot file using the ntldr command.
grub rescue> ntldr /bootmgr
Boot the system: Finally, use the boot command to boot into Windows.
grub rescue> boot
Once you’ve successfully booted into Windows, consider reinstalling Grub or another bootloader to regain access to your Linux system. If you need help with reinstalling a Linux distribution like Debian, check out this helpful Debian installation tutorial.
Conclusion
Grub bootloader is an essential component of many Linux systems, providing support for multiple operating systems and filesystems. When faced with Grub-related issues, Grub rescue commands can help you navigate and troubleshoot the problem. By understanding these commands and their applications, you can tackle boot issues and restore your system’s functionality.
Always remember to back up your data and Grub configuration files to avoid potential data loss. Happy computing!
