How to create table without awk command ?

[kahpeng]

Hi there, I'm new to linux programming. I've read a similar post about my problem but the solution given by the other members is using awk command. I have to solve the same problem without using awk commands. Anybody can help me with the sed commands if I'm not mistaken will do the same thing ?

Question: I need to create a table out from /etc/passwd file with following format:-

User Name User User Group ID Home
--------------- ------- --------------- -----------
John 234 23 /home/john

Any kind soul out there can help me ? Thanks a lot.

{ printf "%-20s\t%s\t%s\t%s\n" "UserName" "UserID" "GroupID" "Home"
	while IFS=: read -r un p uid gid j h s;do
		printf "%-20s\t%d\t%d\t%s\n" "$un" "$uid" "$gid" "$h"
	done</etc/passwd;}
