Help with cmd while using ps

Hi i am new to shell scripting and any help is really appreciated.
my requirement is in,

Code:

ps -e -o pid,uname,cmd

how can i split and take only the cmd part from it.
I tried awk but the issue is when the cmd is returning a lengthy command which itself has some spaces it is truncating the value.for example,

Code:

 ps -e -o pid,uname,cmd

returns below

Code:

 2001 root     /sbin/mingetty /dev/tty6
 2002 root     /sbin/udevd -d
 2003 root     -bash
 2004 root     /sbin/dhclient -1 -q -lf /var/lib/dhclient/dhclient-eth0.leases -pf /var/run/dhclient-eth0.pid eth0

when using awk in ps to fetch only cmd it is truncating value as below,

Code:

 ps -e -o pid,uname,cmd | awk '{ print $3 }'

Code:

 /sbin/mingetty
 /sbin/udevd
 -bash
 /sbin/dhclient

Expected value is

Code:

 /sbin/mingetty /dev/tty6
 /sbin/udevd -d
 -bash
 /sbin/dhclient -1 -q -lf /var/lib/dhclient/dhclient-eth0.leases -pf /var/run/dhclient-eth0.pid eth0

edit by bakunin: please use CODE-tags for commands, data and terminal output. You see for yourself that it looks better and more readable.
