PS: should use "sudo" to see the file. And ~less()~ or ~more()~ will show the file

The following file contains a list of fields about each user:

#+begin_src bash
 head -4 /etc/passwd
#+end_src

#+RESULTS:
| root:x:0:0::/root:/bin/bash                |
| bin:x:1:1::/:/sbin/nologin                 |
| daemon:x:2:2::/:/sbin/nologin              |
| mail:x:8:12::/var/spool/mail:/sbin/nologin |

PS: ~head()~ is used to show only the first four lines.
