The next example, which is run on the inventory-shipped file, prints the first two fields of each input record, with a space between them: $ awk '{ print $1, $2 ...

The $1 stands for the first field, in this case the first column. To print the second column,you would use $2 : awk '{print $2}' information.txt.

Using AWK, print $1 (First column) if the string in the column starts with a specific string? · ' { print $1 }' · '($1 == ^ada) { print $1 }' ...

The awk print $1 command is used to extract the first column(or field) of data from a text input. Let's see with the ...
