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:

mysql:x:117:123:MySQL Server,:/var/lib/mysql:/bin/false

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

grep “/bin/bash” /etc/passwd | awk -F “:” ‘{print $1}’

does that work for you?
