Answer:

The answer is "True".

Explanation:

  • Alias command is normally used for shortening or chain terminal commands with each other. These commands include many shells that are ash, bash, csh, and ksh. The purpose is to use these commands is read and execute commands.  
  • A function is a group of statements that are used to perform a specifics task. In other words, we can say that a function will take values that are passed by the user and somehow manipulate those values for executing commands and function parameters are known as positional parameters.

Suppose that a queue is implemented using a circular array of size 12. What is the value of last after the following operations?
otez555 [7]

Answer:

10

Explanation:

An enqueue operation is a function that adds an element(value) to a queue array. A dequeue operations removes an element from a queue array. Queue arrays follow a first-in-first-out approach, so elements that are first stored in the queue are removed/accessed first(enqueue operations add elements at the rear of the queue array).

The following operations leave 10 elements in the queue of array size 12 after its done:

10 enqueue operations= adds 10 elements

5 dequeue operations= removes 5 elements( 5 elements left in queue)

6 enqueue operations= adds 6 elements(11 elements in queue)

10 dequeue operations= removes 10 elements(1 element left in queue)

8 enqueue operations= adds 8 elements(9 elements in queue)

2 dequeue operations= removes 2 elements(7 elements left in queue)

3 enqueue operations= adds 3 elements(10 elements in queue)

Therefore there are 10 elements in the queue after enqueue and dequeue operations.

podryga [215]

Explanation:

I assume you are on a single host.

To modify the .bashrc for all NEW users, you can edit/modify (with su privilege) the file

/etc/skel/.bashrc

save the file before creating new users.

Be sure to know what you're doing, and test the file before you use it host-wide.

For existing users, you can have them do the modifications/additions individually in case they have already modified their own version.
