Linux Shell Scripting

This task takes me through practical steps in learning Linux bash scripting.

---

Task One

Creating Directories

1. I created a folder named shell-scripting.

2. I used the cd command to change into the shell-scripting folder before creating the my_first_shell_script.sh file.

3. Using Vim, I created a file called my_first_shell_script.sh.

4. I used ls -latr to confirm that the file was successfully created.

5. I ran the script using ./my_first_shell_script.sh but got an error: "Permission denied!" because the file wasn't executable, as I noticed in the file listing.

Task Two

Adding Permissions to the File

1. I added executable permission to the file using chmod +x my_first_shell_script.sh.

2. I ran the shell script and noticed that only the folders were created.

Note: I couldn't create the users because I am running Vim and Terminal on macOS, and the useradd command is not supported. This is why it didn't run.

Task Three

Variable Declaration and Initialization

1. In my shell, I was able to create a variable called name and retrieve its value from the terminal.

Adding Comments

# This is a single-line comment in Bash
echo "Hello, you are learning Bash Scripting on DAREY.IO!" # This is also a comment, following a command

# This is another way to create
# a multi-line comment. Each line
# is prefixed with a # symbol.
echo "Here is an actual code that gets executed"

Conclusion

I was able to successfully complete the tasks, including creating directories, adding permissions to files, and working with variables in Linux shell scripting. However, due to the limitations of macOS, I couldn't use the useradd command to create users.
