After going to the CS lab someone helped me figure out the problem. I needed to be in a certain working directory at first, and I wasn't. After switching to that directory all I needed was the command:
../UnixCourse/fileAsst/*.txt
and that took care of it for me. Thanks to everyone that helped and I hope this helps someone else.

Which of the following modes of replication requires a very low latency network connection and ensures data remains in synch wit

Snowcat [4.5K]

Answer:

b. Synchronous replication

Explanation:

Replication of data in storage partitions or in a number redundant array of independent disk drives helps to promote redundancy, as implied, and faulty tolerance to reduce loss of data.

There are two categories of replication and they are synchronous and asynchronous replication.

Synchronous replication requires low latency network site to mirror data, while asynchronous replication mirrors data in large metropolitan area in high latency networks.

You want to create a directory called ~/Documents/papers, but you’re not sure that the ~/Documents directory exists. What comman

SCORPION-xisa [38]

Answer: e) mkdir -p ~/Documents/papers

Explanation:

As the question says we want to create a directory called ~/Documents/papers, but we are not sure whether it exist or not so we would type the command for making directory starting with mkdir.

Here mkdir means make directory. Followed by mkdir we will use -p. Here p is used to create all the directories for getting us the directory we want and its advantage is that it would ignore all the errors if the directory already exist.

Followed by the name of the directory that we want to create.

So the desired answer for the given condition would be mkdir -p ~/Documents/papers

What will the following code display? #include using namespace std; void doSomething(int); int main() { int x{2}; cout <<

Leno4ka [110]

Answer:

The code will display the following on the screen:-

Explanation:

The output is like this because x{2} assigns the value 2 to the integer x.First the value of x is printed on the screen that is 2 and that newline is used to go to the next line.After that function is called doSomething with x passed as the argument. doSomething function assigns the value zero to the variable passed and prints it on the screen.So the next line is 0.Since x is passed by value so no changes will appear in the original argument.Hence the last line printed is 2.

Using recursion, write a program that asks a user to enter the starting coordinates (row, then column), the ending coordinates (

Luden [163]

Answer:

The program in Python is as follows

def Paths(row,col):

if row ==0 or col==0:

return 1

return (Paths(row-1, col) + Paths(row, col-1))

row = int(input("Row: "))

col = int(input("Column: "))

print("Paths: ", Paths(row,col))

Explanation:

This defines the function

def Paths(row,col):

If row or column is 0, the function returns 1

if row ==0 or col==0:

return 1

This calls the function recursively, as long as row and col are greater than 1

return (Paths(row-1, col) + Paths(row, col-1))

The main begins here

This prompts the user for rows

row = int(input("Row: "))

This prompts the user for columns

col = int(input("Column: "))

This calls the Paths function and prints the number of paths

print("Paths: ", Paths(row,col))
