help command don't work

[rocck]

i had installed kubuntu 8.04-kde4 edition
but
when i input
the command
sudo kate /etc/apt/sources.list

it shows

p@ubuntu:~$ sudo kate /etc/apt/sources.list
sudo: kate: command not found


why?

[arabian]

原因是sudo的路径里面没有/usr/lib/kde4/bin

sudo /usr/lib/kde4/bin/kate
