+## remake
+
+### Instructions
+
+Create a file `remake.sh`, which will take one argument, the relative path of a directory, and will create new files and directories in it.
+
+If the number of given arguments is not one, your script should print `Error` and exit with the status code 1.
+
+Below the expected behavior of your script: 
+
+```console
+$  bash remake.sh given-path
+$  ls -ltr given-path 
+total 8
+-r--r---w- 1 nprimo nprimo    0 Jan  1 00:01 ciao 
+drwxrwxrwx 2 nprimo nprimo 4096 Jan  2 00:01 mamma
+-r-------- 1 nprimo nprimo    0 Jan  3 00:01 guarda
+-rw-r---w- 1 nprimo nprimo    0 Jan  4 00:01 come 
+dr--r-x-w- 2 nprimo nprimo 4096 Jan  5 00:01 mi
+-r---w---x 1 nprimo nprimo    0 Jan  6 00:01 diverto
+$ 
+```
+
+### Hints
+
+- `mkdir <relative-path>` command is used to create a new directory in the specified `<relative-path>`. For example:
+
+```console
+$  ls -l
+total 0
+-rw-rw-r-- 1 nprimo nprimo 0 Jan 12 14:26 a
+-rw-rw-r-- 1 nprimo nprimo 0 Jan 12 14:26 b
+-rw-rw-r-- 1 nprimo nprimo 0 Jan 12 14:26 c
+$  mkdir d
+$  ls -l 
+total 4
+-rw-rw-r-- 1 nprimo nprimo    0 Jan 12 14:26 a
+-rw-rw-r-- 1 nprimo nprimo    0 Jan 12 14:26 b
+-rw-rw-r-- 1 nprimo nprimo    0 Jan 12 14:26 c
+drwxrwxr-x 2 nprimo nprimo 4096 Jan 12 14:26 d
+$
+```
+
+- `touch <file-path>` command is used to change the modification and/or access time of the specified `<file-path>` to the current time. If the file does not exist yet, a new empty file is created at the specified `<file-path>`.
+
+The flag `-t` allow to specify the time in the format `[[CC]YY]MMDDhhmm[.ss]` instead of the current time.
+
+- `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!
