+“The best TDD can do, is assure that code does what the programmer thinks it should do. That is pretty good BTW.”

+## easy-perm
+
+### Instructions
+
+Create a file `easy-perm.sh`, which will change the default permissions for the `example.txt` and `example2.txt` files inside the folder `easy-perms`, to the ones bellow:
+
+Now
+
+Expected Output:
+
+```console
+$ ls -l easy-perm
+total 8
+-rwxr--rw- 1 user user 689 dez 13 16:14 example2.txt
+-rw-r--r-- 1 user user 348 dez 13 16:14 example.txt
+$
+```
+
+### Hints
+
+-`chmod` The chmod, or change mode, command allows an administrator to set or modify a file’s permissions. Every UNIX/Linux file has an owner user and an owner group attached to it, and every file has permissions associated with it. The permissions are as follows: read, write, or execute.
+
+This is what the default permissions looks like when you create a file.
+
+```console
+$ touch example.txt
+$ ls -l example.txt
+-rw-rw-r-- 1 user user 348 dez 13 15:31 example.txt
+$
+```
+
+This is what it looks like if you want to give permissions to read, write and execute to every group.
+
+```console
+$ chmod 777 example.txt
+$ ls -l example.txt
+-rwxrwxrwx 1 user user 348 dez 13 15:31 example.txt
+$
+```
+
+> You have to use Man or Google to know more about commands flags, in order to solve this exercise!
+> Google and Man will be your friends!
