What is awk print $1?

In this tutorial, we will see about what is meant by awk print $1.

awk is interpreted programming language. It is very powerful and used for text processing.Awk stands for the names of its authors “Aho, Weinberger, and Kernighan”.

awk print $1

As said before, awk can be used for text processing.awk treats tab or whitespace for file separator by default.
Awk actually uses some variables for each data field found.

  • $0 for whole line
  • $1 for first field
  • $2 for second field
  • $3 for third field
  • $n for nth field

so here print $1 represents first field in the file.

Let’s understand with the help of an example.

$ cat > sample.txt

This is sample file
Java is programming language.
This is Java tutorial
I know Java very well.

Let’s run the command now

$awk ‘{print $1}’ sample.txt


If you notice awk ‘print $1’ prints first word of each line.
If you use $3, it will print 3rd word of each line.

$awk ‘{print $3}’ sample.txt


Let’s use csv file now for demonstration

$ cat > countries.csv


Let’s print first column of csv file using awk print $1 command. We need to provide explicit delimeter over here.

$awk -F’,’ ‘{print $1}’ countries.csv


That’s all about awk print $1 command.
