Question

Describe what each of the following commands do

rm /tmp/f

mkfifo /tmp/f

Answer 1

Here I am explaining the both commands in LINUX/UNIX,see below

rm /tmp/f :-

rm is used for remove a directory or a file,And which deletes the all files or information in the directory or file.

In above command rm is used on the directories called /tmp/f

                tmp(directory) ---> f (directory)

So,it will deletes all the files in the tmp directory.

mkfifo /tmp/f :

FIFO: first in,first out FIFO is method of processing the data ,where the data first received is the first to be sent out after processed.And which one will come first ,that must be executed first.

mkfifo command is used for make a named pipes(FIFO's) with the given NAME's.

mkfifo /tmp/f   -> This command is creating a named pipe at /tmp/f (directory).
