In this article, we will walk you through the step-by-step process of saving a file in vi on Linux. We will cover various methods, including saving with a specific name, saving and exiting vi, saving and continuing editing, and more. Whether you are a beginner or an experienced Linux user, this guide will provide you with all the information you need to save files in vi.

Step 1: Enter Command Mode

Before you can save a file in vi, you need to enter command mode. To do this, press the Esc key on your keyboard. This will ensure that you are in command mode and ready to execute commands.

Once you are in command mode, you can proceed to the next step to save the file.

Step 2: Save the File

To save the file in vi, you can use the “:w” command. Type “:w” (without quotes) in command mode and press Enter. This command tells vi to write the current file to disk, effectively saving any changes you have made.

For example, if you have made changes to a file named “example.txt”, you can save the file by typing “:w” and pressing Enter. Vi will then save the changes to the “example.txt” file.

Step 3: Save with a Specific Name

If you want to save the file with a specific name, you can use the “:w filename” command. Replace “filename” with the desired name for the file.

For example, if you want to save the file as “newfile.txt”, you can type “:w newfile.txt” in command mode and press Enter. Vi will then save the file with the specified name.

Step 4: Save and Exit vi

If you want to save the file and exit vi at the same time, you can use the “:wq” or “:x” command. Type either “:wq” or “:x” in command mode and press Enter.

For example, if you want to save the file and exit vi, you can type “:wq” or “:x” and press Enter. Vi will save the file and close the editor.

Step 5: Save and Continue Editing

If you want to save the file and continue editing, you can use the “:w filename” command followed by the Enter key. Replace “filename” with the desired name for the file.

For example, if you want to save the file as “newfile.txt” and continue editing, you can type “:w newfile.txt” and press Enter. Vi will save the file with the specified name and keep the editor open for further editing.

Step 6: Save the File Under a Different Name

If you want to save the file under a different name, you can use the “:saveas filename” command. Replace “filename” with the desired name for the file.

For example, if you want to save the file as “newfile.txt”, you can type “:saveas newfile.txt” in command mode and press Enter. Vi will save the file with the specified name.

Step 7: Shortcut Key Combination

If you prefer using shortcut key combinations, you can save the file and exit vi by pressing “Shift + ZZ” simultaneously. This key combination is equivalent to the “:wq” command.

For example, if you want to save the file and exit vi, you can press “Shift + ZZ”. Vi will save the file and close the editor.

Step 8: Save Without Quitting vi

If you want to save the file without quitting vi, you can use the “:sav filename” command. Replace “filename” with the desired name for the file.

For example, if you want to save the file as “newfile.txt” without quitting vi, you can type “:sav newfile.txt” in command mode and press Enter. Vi will save the file with the specified name and keep the editor open.

Step 9: Save and Append Changes to an Existing File

If you want to save the file and append the changes to an existing file, you can use the “:w >> filename” command. Replace “filename” with the name of the existing file.

For example, if you want to save the file and append the changes to a file named “existingfile.txt”, you can type “:w >> existingfile.txt” in command mode and press Enter. Vi will save the changes and append them to the “existingfile.txt” file.

Step 10: Save and Overwrite an Existing File

If you want to save the file and overwrite an existing file without confirmation, you can use the “:w!” command. This command tells vi to save the file and overwrite the existing file without asking for confirmation.

For example, if you want to save the file and overwrite a file named “existingfile.txt” without confirmation, you can type “:w!” in command mode and press Enter. Vi will save the file and overwrite the “existingfile.txt” file.

Step 11: Save and Append Changes to an Existing File without Confirmation

If you want to save the file and append the changes to an existing file without confirmation, you can use the “:w! >> filename” command. Replace “filename” with the name of the existing file.

For example, if you want to save the file and append the changes to a file named “existingfile.txt” without confirmation, you can type “:w! >> existingfile.txt” in command mode and press Enter. Vi will save the changes and append them to the “existingfile.txt” file without asking for confirmation.

Step 12: Preserve Original File’s Timestamp

If you want to save the file and preserve the original file’s timestamp, you can use the “:preserve” or “:keepjumps w” command. This command tells vi to save the file while preserving the original file’s timestamp.

For example, if you want to save the file and preserve the original file’s timestamp, you can type “:preserve” or “:keepjumps w” in command mode and press Enter. Vi will save the file and maintain the original file’s timestamp.

Step 13: Save and Make the File Read-Only

If you want to save the file and make it read-only, you can use the “:w !chmod -w %” command. This command tells vi to save the file and remove the write permission for the file.

For example, if you want to save the file and make it read-only, you can type “:w !chmod -w %” in command mode and press Enter. Vi will save the file and make it read-only.

Step 14: Save and Make the File Executable

If you want to save the file and make it executable, you can use the “:w !chmod +x %” command. This command tells vi to save the file and add the execute permission for the file.

For example, if you want to save the file and make it executable, you can type “:w !chmod +x %” in command mode and press Enter. Vi will save the file and make it executable.

Step 15: Save and Make the File Writable by the Group

If you want to save the file and make it writable by the group, you can use the “:w !chmod g+w %” command. This command tells vi to save the file and add the write permission for the group.

For example, if you want to save the file and make it writable by the group, you can type “:w !chmod g+w %” in command mode and press Enter. Vi will save the file and make it writable by the group.

Step 16: Save and Make the File Writable by Others

If you want to save the file and make it writable by others, you can use the “:w !chmod o+w %” command. This command tells vi to save the file and add the write permission for others.

For example, if you want to save the file and make it writable by others, you can type “:w !chmod o+w %” in command mode and press Enter. Vi will save the file and make it writable by others.

Step 17: Save and Make the File Writable by Everyone

If you want to save the file and make it writable by everyone, you can use the “:w !chmod a+w %” command. This command tells vi to save the file and add the write permission for everyone.

For example, if you want to save the file and make it writable by everyone, you can type “:w !chmod a+w %” in command mode and press Enter. Vi will save the file and make it writable by everyone.

Step 18: Save and Change the Owner to a Specific User

If you want to save the file and change the owner to a specific user, you can use the “:w !chown username %” command. Replace “username” with the desired username.

For example, if you want to save the file and change the owner to a user named “john”, you can type “:w !chown john %” in command mode and press Enter. Vi will save the file and change the owner to the specified user.

Step 19: Save and Change the Group Ownership to a Specific Group

If you want to save the file and change the group ownership to a specific group, you can use the “:w !chgrp groupname %” command. Replace “groupname” with the desired group name.

For example, if you want to save the file and change the group ownership to a group named “developers”, you can type “:w !chgrp developers %” in command mode and press Enter. Vi will save the file and change the group ownership to the specified group.

By following these step-by-step instructions, you can easily save files in vi on Linux. Whether you need to save a file with a specific name, save and exit vi, or make changes to file permissions, vi provides a range of options to suit your needs. With practice, you will become proficient in saving files in vi and be able to efficiently manage your files in the Linux operating system.
