hi munalemj the above code secion you refered is the par which allows us to redirect the output from appearing on screen to /dev/null which is equivalent of destroying what ever is received as output.

the reason for doing this is because we are more interested in the return state of the program instead of the output.

also 2> /dev/null allows us to redirect the error stream to /dev/null.

error stream is outputs which are marked as error.

Would you be able explain a bit or leave comments for newbies to understand please…
E.g. what does the below line of code do.. especially the 1 >>/dev/null and 2>/dev/null

until expr $as – 1 >>/dev/null 2>/dev/null
