Solution

1. cat < file1 >> file2 cat < file1 will usually write the file file1 to screen, but as you\'re redirecting the output using >> operator, which means the output of the previous command is concatenated to file2.

So, the answer is: (a). file1 content is appended to file2.

2. (a). echo new > /test/part1 will write the string new to the file /test/part1. is False.

(b). echo new >> /test/part1 will append the string new to the content in the file /test/part1. is True.

(c). echo new | test/part1 this will lead to an error, as the second part is not a command. False.

(d). /test/part1 < echo new will lead to an error. False.

3. (d) Background process can start a new subshell. True.

4. (b) Double quotes.

5. (a). Every unix process terminates with an exit value. True. And all the remaining options are false.
