Answer:
dd if=/dev/drive1 of=/dev/backup
Explanation:
Linux operating system is an open-source computer application readily available to system operators. The terminal is a platform in the operating system used to write scripts like bash and directly communicate with the system kernel.
There are two commands used in bash to copy files, the "cp" and "dd". The dd is mostly used to copy files from one storage or partition to another. The syntax of dd is;
dd if= (source partition/directory) of= (target partition/directory)
What will happen is the file will be open by someone else and will be open as read only. I hope this helps!
Answer:
x = int(input ("enter first number: "))
y = int(input ("enter second number: "))
z = int(input ("enter third number: "))
print('%6d %6d %6d' %(x,y,z))
Explanation:
Using python programming language we receive three integers variables (x,y,z) then using string formatting (%6) which specifies that the output should be right justified with a width of 6, the values are printed out.
You'll need a helper variable for this, so depending on your programming language, the solution becomes:
int helper;
helper = arr[i];
arr[i] = arr[j];
arr[j] = helper;
