I've got an exercise to do in which I have been given a fictional email record in which the owner of the email got invited to a certain place for vacation. The log is large though, so to speed things up, I have to use grep in a certain way to find the address where the owner of the email address is heading.

The basic form of how an address is written as:

name firstName
streetName streetNumber
postalCode(zip) City

Now I know that postal codes usually are 5 ciphers long, so I can start looking for the line with the postal code. Until now, I did it like this:

grep -C2 ^[0-9][0-9][0-9][0-9][0-9] emails

This command gives me all lines that start with 5 ciphers in a row and its surrounding two lines (-C2). With this I was really able to find the address, yet there's still a lot of unnecessary lines that show up around it. I have to specify the search to only get the address.

So I tried searching for a line that starts with 5 ciphers and ends with any letter like this:

grep -C2 ^´[0-9][0-9][0-9][0-9][0-9][A-Z]$´ emails

But it ends up finding nothing... It's probably because it searches for a line that only contains 5 ciphers and a letter. But I don't know how to tell grep to search for a line that only searches for a line that starts with 5 ciphers AND ends with a letter(or even better, a word).

My next best try would be searching for the name and the first name by searching for a line which contains only two words. But I don't know how to do that and I can't find any discussion in which this is explained.

I hope you guys can help me out, please?
