Awk is a powerful text-processing tool that allows you to manipulate and analyze structured data. The `length` function in Awk is used to calculate the length of a string or the number of fields in a record.
Here's an example of how to use the `length` function in Awk:
```awk
$ echo "Hello, World!" | awk '{ print length }'
```
In this example, the `length` function is used to calculate the length of the input string "Hello, World!". The output will be 13 because there are 13 characters in the string.
You can also use the `length` function with fields in Awk. For example:
```awk
$ echo "apple orange banana" | awk '{ print length($2) }'
```
In this example, the `length` function is used to calculate the length of the second field in the input string "apple orange banana". The output will be 6 because the second field is "orange" and it has 6 characters.
