Basically, I have a random file of users, and I need to sort out which ones have a shell of /bin/bash/ using sed, cut, sort, or awk. This is the file:

I also have to write a pattern matching regular expression that matches 8 characters of lowercase, upper case, numbers and symbols.
I can do basic scripting and what not, I’m just out to lunch on this shit.
Any help would be appreciated.
Cheers
