Answer 1

I created the scripts in Kali Linux since I don't have Fedora Server Virtual Machine. But you need not worry as the steps provided will work in any Linux Operating System.

At first, I created the directory 'labs' with the command: mkdir labs in the root directory or the home directory.

We create the lab1 file , we use the command touch lab1 . Now we create the script.

The first line of a bash script should always sstart with a #!/bin/bash which denotes that the script will use the interpreter as the bash shell. THis is very much important in create an linux script.

Now, we take the user input with the following command read -p "Enter your name:" name which takes the takes and put it in the variable 'name'

The same is done for inputs address and number
Now we echo the values of $name, $address and $number to the info.txt file which is created along.


We are done with the script now, it gets created with the inputs given by us.
lab1.sh file:

#!/bin/bash

read -p "Enter your name: " name

read -p "Enter your address: " address

read -p "Enter your phone number: " number

echo "$name" >> info.txt

echo "$address" >> info.txt

echo "$number" >> info.txt

Here is the screenshot to the script and the output:

chmod -x make this script executable
chmod 777 makes the file/script read, write, and execute permission for all the users.

2) We use echo $USER print the logged in user and id -u to print numberic id.

Make sure to use #!/bin/bash at the start of the program.

With the help of echo command, we print the result.

lab1.sh file

#!/bin/bash
echo "Username:$(echo $USER)"
echo "User ID:$(echo $(id -u))"

Always remember to give permissions to files and foldes with the chmod commnad in linux.
