In Python, a regular string is a string that is interpreted according to the rules of the Python interpreter. This means that special characters, such as newline (\n) or tab (\t), are processed and converted into their appropriate representation. For example, the string "Hello\nWorld" would be interpreted as two separate lines, with "Hello" on the first line and "World" on the second line.
A raw string, on the other hand, is a string that is taken exactly as it is, without any special processing. Raw strings are denoted by prefixing the string with the letter r. For example, the string r"Hello\nWorld" would be taken literally, without the \n being interpreted as a newline character.
The main difference between a regular string and a raw string is that a regular string allows for special characters and escape sequences to be processed, while a raw string does not. Raw strings are often used when dealing with file paths or regular expressions, where backslashes are a common part of the syntax. By using a raw string, you can ensure that the backslashes in the string are taken literally, without being interpreted as escape characters.
Here's an example in Python that demonstrates the difference between a regular string and a raw string:
# Regular string
string1 = "Hello\nWorld"
print(string1)
# Raw string
string2 = r"Hello\nWorld"
print(string2)Hello World Hello\nWorld
As you can see, the regular string string1 is interpreted by the Python interpreter and the newline character (\n) is processed, resulting in "Hello" being printed on one line and "World" being printed on the next line.
In contrast, the raw string string2 is taken exactly as it is written, and the newline character is not processed. The output of string2 is the literal string "Hello\nWorld".

Linux Toolbox is a tool for Linux operating systems, which allow to check the different type of system information. For example - date, time, device owner, disk usages, memory usages, CPU usages and etc. Another feature of Linux Toolbox is - it will show the current monthly calendar for any year, it can manage a huge of contact information, and it can create a notebook.
The sole intention behind the consideration of this project is to generate and manage to show some system information. This project has been developed considering note and contact information keeping the context of the user in mind. Here, the data has been stored in a few text files in the storage.
To develop Linux Toolbox, we use Visual Studio Code IDE for code edit. The Linux Toolbox is a simple GUI-based application that has been developed in Shell Script. It is allowed to show system information, enables a store of notebook and contact information. Those are essentially databases that track all information for a user and a user can avail the benefits of using this application. Here, linux_toolbox.sh is the main file. There is also have a file calendar.sh that can show a month of calendar for the user.
In this application, users can sign-up, log-in and see the monthly calendar. Also, users can use notebooks and add favorite contact information. We worked with Bash language and use Graphical User Interface via the YAD library. In the case of Bash/Shell Script, we have used some functions such as calendar, home, notebook, view_all_note, contact, and etc which have been used to reduce the code space.

fiWe have been able to meet the goals we set for ourselves in this project. Our code worked properly and was able to run Linux Toolbox. Also, the additional functions we added for user interaction all worked the way we initially expected. Each step along the way we tested our code to make sure everything was properly mapped.
After running Linux Toolbox, it will show the Sign-up window for the first time. Once the user has successfully signed up, the user will be shown a login window. And then the user needs to log in to use Linux Toolbox. Here users can use a blank email and password when signing up.
Figure-1: Sign-up and Login Window
After successful login, users will be able to view system information, add notebooks, and manage contact information.

Our goal was to see the monthly calendar, add notes, manage contact, and view system information. In this project, our code worked properly and was able to successfully run Linux Toolbox. Also, the additional functions we added for user interaction all worked the way we initially expected. Each step along the way we tested our code to make sure everything was properly mapped.
Although Linux Toolbox runs properly, there is some limitation for this application.
In this project, we gained a lot of knowledge and experience working with the Linux operating system. We learned how to work Bash language. Also, we learned more about the basic principles of Linux application. Our team members have made improvements in various areas such as developing a structured information pathway for all types of software and understanding more about state machines. Although this is a YAD base project, it was a great experience in developing software. The principle behind constructing a Linux Toolbox is to effectively retrieve and implement any information. All the information related to a particular people can be linked and archived only to be retrieved later when they are required most.
Linux Toolbox is one of the useful applications used to show the system information. This type of software can be used to note down user information and create contact and also manage the contact information.
In the future, we have planned to add more features for Linux Toolbox. For example, users can manage background applications such as kill or end process for Linux/GNU operating system. It would be handy for all Linux users. We have a plan to increase the limit of features. And we will upgrade it with many more facilities in the future.
