UNIX case study - 2

I'm writing a script that provides a menu to manipulate records. I'm having a problem, however. The first option I'm writing is simply to display all of the records in a supplied file.

The supplied file ('records') currently contains sample data, this data is:

95671660:Jones:Sarah:45:sales manager
93272658:Smith:John:43:technical manager
98781987:Williams:Nick:35:computer officer
99893878:Brown:Sarah:12:electrician
95673456:Couch:David:26:chef
95437869:Anderson:Sarah:19:CEO

I need to display this data as standard output. It needs to be arranged in 5 columns, each left-justified. The column order is family name (i.e. Jones), first name, telephone number , department number (i.e. 45) and job title. In needs to be sorted in ascending alphabetical order of family name (i.e. Anderson, Brown etc.)

Basically, it should look (something) like this:

Code:

Anderson Sarah 95437869 19 CEO
Brown Sarah 99893878 12 electrician
Couch David 95673456 26 chef
Jones Sarah 95671660 45 sales manager
Smith John 93272658 43 technical manager
Williams Nick 98781987 35 computer officer

I've been trying various solutions using cut and gawk. It's an sh script. Honestly, though, it's getting stupid. Look:

Code:

# Print records option.
1) echo -e "Debug: User has selected print option.\n"
#cut -f2 -d: records | sort
awk '$2 $3 $1 $4 $5 {print}' records
#cut -f3 -d: records
#cut -f1 -d: records
#cut -f4 -d: records
#cut -f5 -d: records
echo -en "\nPress Enter to continue... "
read
;;

It's pretty obvious I haven't a clue how to use (g)awk properly, lol. I'm used to using cut for extracting single columns. I've never had to extract and format a table like this, using unix.

Can anyone help?
