ztail
Instructions
Write a program called ztail that has the same behaviour as the system command tail, but which takes at least one file as argument.
-
The only option to be handled is
-c. This option will be used in all tests. -
For this program the "os" package can be used.
-
For the program to pass the tests the convention for the return code of program in Unix systems should be followed (see os.Exit).
-
Handle the errors and output the same error messages as
tail. -
For more information consult the man page for
tail.
Note:
This program is gonna be tested against tail, be sure to check all the different error messages with different permutations of the arguments.
