Can you give another example of $0?

Certainly! Here's another example demonstrating the use of $0 in awk.

Suppose you have a file named data.txt with the following content:

Alice 30
Bob 25
Charlie 35

You can use awk to print the entire line along with a custom message. For example:

awk '{ print "Record: " $0 }' data.txt

Output:

Record: Alice 30
Record: Bob 25
Record: Charlie 35

Explanation:

• The command prints "Record: " followed by the entire line (represented by $0) for each line in the data.txt file.

This shows how $0 can be used to access and manipulate the complete line of input in awk. If you have more questions or need further examples, feel free to ask!
