Awk is a powerful and versatile tool in Linux that is used for text processing and manipulation. One of the many useful commands that can be used in conjunction with Awk is the ‘next’ command. The ‘next’ command allows you to skip the current record and move on to the next one.

Here’s how you can use the ‘next’ command with Awk in Linux:

1. First, open a terminal window in Linux.

2. Next, create a sample text file that we can use for demonstration purposes. You can use a text editor like Nano or Vim to create a file. For example, you can create a file named ‘data.txt’ with the following contents:

Tom 25
Jerry 30
Spike 28

1. Once you have created the sample text file, you can use the Awk command to process the data. For example, you can use the following command to print only the records where the age is less than 30:

awk '{ if ($2 < 30) {print $1, $2} }' data.txt

This command will output:

Tom 25
Spike 28

1. Now, let’s use the ‘next’ command to skip the records where the age is less than 30:

awk '{ if ($2 < 30) {next} else {print $1, $2} }' data.txt

This command will output:

Jerry 30

As you can see, the ‘next’ command allows you to skip records based on a certain condition. In this case, we skipped the records where the age is less than 30 and only printed the record where the age is equal to or greater than 30.

Overall, the ‘next’ command in Awk is a handy tool for skipping records in a data set based on specific conditions. It helps you to process data more efficiently and selectively. Next time you are working with data in Linux, remember to make use of the ‘next’ command with Awk to streamline your text processing tasks.
