We're working from the command prompt so it's useful to know how best to find files. The command we're going to take a sneeky peeky at is 'find'

find / -name myfile.log

Breakdown;
find - the command
/ - where we're searching. If we only wanted to search in the /etc/ folder the command would look like this 'find /etc/ -name myfile.log'
-name - tell the OS we are looking for the name of a file
myfile.log - the name of the file you're searching for

More to come
