UNIX for Dummies Questions & Answers

Hi,

I am pretty new to the unix community and have encountered a problem that I am trying to solve. I have 2 files one of which is called passwd file that looks like the following

Sample Output

Code:

daemon:x:1:1:daemon:/usr/sbin:/bin/sh
bin:x:2:2:bin:/bin:/bin/sh
sys:x:3:3:sys:/dev:/bin/sh

and the other a file called group which looks like the following

Sample Output

Code:

gnats:x:41:
shadow:x:42:
utmp:x:43:
video:x:44:john,martin
sasl:x:45:

So using a combination of sort/cut/grep/awk/join/paste/sed I need to create a txt file where the output would be placed and looks like the following based on user is the passwd file having :"bin/bash" on their column. The new file will have the users and groups both in alphabetical order. It should look something like this apparently.

Sample Output

Code:

User: prof
Groups: course prof test

User: student
Groups: course othercourse student

I can also us awk scripting, and sort of know that I can use a pipe to do it, but do not know the corrext syntax it would be to complete the statement. If anyone can help me please it would be greatly appreciated.
