determine pid from ps -ef | grep something

# 8  
ps -ef | grep "/var/lib/dpkg/lock" | awk '{print $1}'

will give the PID.

Do a
ps -ef

and verify that that is the process you wanted to kill before killing it.

the result of your help command line returned "ubuntu" ???

is that a process name ?

if so,

is it possible to kill ubuntu ?
when you kill a process, is it possible to kill it by its name or
how to know the pid of a process when you have the name of it ?

That is not the prcess name but the UID or the user name

yu should get the PID with this

ps -ef | grep "/var/lib/dpkg/lock" | awk '{print $2}'

if i'm not too stupid, i understood that being logged as ubuntu on the live cd,

the /var/dpkg/lock file was used by me with (linux user account name "ubuntu"). The $1 value is "ubuntu", the $2 should be the pid of the process that is using it, is it right ?

You are correct, $1 is the user. If you logged in as ubuntu, then it is you.
$2 is the PID of your process that is using the file /var/dpkg/lock

If things are not clear, do man ps

the reason why my user account is ubuntu is because i boot on live cd of ubuntu (of course)
unless i make my own ubuntu live cd (which i don't even know anything at it)
every time you use a live cd of it, your default user account will be stated as ubuntu

it is stunning the number of processes that i get using ps -e or -ef on mac os x compared to the number with ubuntu live. but it 's understandable because i used the last version 9 of ubuntu and you can't be as at ease on a live than on a desktop hdd boot installed system.

i got result: 3058, then i killed

then i got error:
bash: kill: (3058) - Aucun processus de ce type
(no such process)
