awk script combining mutiple commands
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.

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
