. To redirect the standard output from a command use the > (greater than) symbol followed by the name of the output file. If the file that you redirect standard output to does not already exist it will be created. For example: grep Smith /etc/passwd > popular . This redirects the standard output from the grep command so that it goes to the file popular . This file will contain all occurrences of the string Smith that were found in the /etc/passwd file. **Caution** . Did You Know? .
