Level Goal

there are 2 files in the homedirectory: passwords.old and passwords.new. the password for the next level is in passwords.new and is the only line that has been changed between passwords.old and passwords.new
NOTE: if you have solved this level and see ‘Byebye!’ when trying to log into bandit18, this is related to the next level, bandit19

Solution

we will use the diff command to get the differences between the two files

as we can see the change is at line 42, and the password for user bandit18 is kfBf3eYk5BPBRzwjqutbbfE887SVc5Yd
