+## head-and-tail
+
+### Instructions
+
+Create the script `head-and-tail.sh` wich will show the first and last lines of the file `HeadTail.txt`
+
+- Where to look : https://assets.01-edu.org/devops-branch/HeadTail.txt
+
+- What to use : `curl` and `head` and `tail`
+
+- The output should be exactly like the example bellow but with the expected name
+
+```console
+$./head-and-tail.sh | cat -e
+Hello My username is: <...>,$
+so my passwd is: <...>$
+$
+```
+
+### Hints
+
+With `curl` you can get the content of the file from the url:
+
+```console
+$curl https://assets.01-edu.org/devops-branch/HeadTail.txt
+<...>
+$
+```
+
+`head` print the top N number of data of the given input. By default, it prints the first 10 lines of the specified files:
+
+```console
+$head file
+<first 10 lines>
+$head -1 file
+<first 1 line>
+$
+```
+
+`tail` print the last N number of data of the given input. By default, it prints the last 10 lines of the specified files:
+
+```console
+$tail file
+<last 10 lines>
+$tail -1 file
+<last 1 line>
+$
+```
+
+May you will need to use `pipe (|)` and "&&".
