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.

6. (c). 3.

7. (b). Counts the number of 1s in binary representation.
