Please need help with detail instructions. Thank you

   Unix Shell Scripting and Makefile

1. Write a script safe_rm, which does all of the following:
   .It takes one argument, which is a file name with no wildcard expressions.
   .If this file does not exist in the current directory, report "file does not exist!".
   .If this file do exist, make a copy of it by attaching at the end ".bak", and then remove the original file.
For example if there is a file with the name "foo.c" in the current folder, by running:
./safe_rm foo.c
the program should create a le called "foo.c.bak", which is exactly the same as "foo.c" except
for the name; and the original file "foo.c" should be deleted.
