Printing each input line/record

We can print each input record of the input file in multiple ways, as shown in the following example. All the given examples will produce the same result by printing all the input records of the input file.

In our first example, we specify the empty pattern without any action statement to print each input record of the input file, as follows:

$ awk '//' empinfo.txt

In this example, we specify the print action statement only, without giving any pattern for matching, and print each input record of the input file, as follows:

$ awk '{ print }' empinfo.txt

In this example, we specify the $0 default variable, along with the print action statement, to print each input record of the input file, as follows:

$ awk '{ print $0 }' empinfo.txt

In this example, we specify the empty expression along with the print action statement to print each input record of the input file, as follows:

$ awk '//{ print }' empinfo.txt

All of the given examples perform the basic printing operation using AWK. On execution of any of the preceding examples, we will get the following output:
