Create a file named answer and give the following command:
$ > answers.0102 < answer cat
Explain what the command does and why. What is a more conventional
way of expressing this command?
Reading the command line from left to right, it instructs the shell to redirect
standard output to answers.0102, to redirect standard input to come from
answer, and to execute the cat utility. More conventionally, the same com-
mand is expressed as
$ cat answer > answers.0102
or simply
$ cp answer answers.0102
