Matching at the end of a string

The unquoted dollar, $, matches the string at the end of the line. The '$' is only the anchor if it is the last character in the regular expression. For example, '0$' matches all the lines that end with 0. It will print employee details of those whose salary ends with the '0' character in the employee database:

$ awk '/0$/{ print }' emp.dat

The output on execution of this code is as follows:
