samba - Oct 2010 - smbstatus questions

Hello list,

I'm running a samba 3.5.3 CTDB cluster, found the output is different

Q1:  What does the "0:" mean in pid column? There was no such stuff in
non-CTDB smbstatus output.

<snip>
samba_01:~ # smbstatus -S 2>/dev/null

Service      pid     machine       Connected at
-------------------------------------------------------
ben          0:21363   samba         Mon Oct 25 17:59:35 2010
ben          0:21442   samba         Mon Oct 25 17:59:39 2010

<snip>

Q2: How to parse smbstatus to capture service column and pid column? as in
case of homes share the service is named as username, while domain username
may contain whitespace(s)?

<snip>
samba_01:~ # smbstatus -S 2>/dev/null

Service      pid     machine       Connected at
-------------------------------------------------------
ben                     0:21363   samba         Mon Oct 25 17:59:35 2010
benjamin linus       0:21442   samba         Mon Oct 25 17:59:39 2010   
<<
"benjamin[space]linux"
james  ford            0:21550   samba         Mon Oct 25 18:00:29 2010
<< "james[space][space]ford", awk/cut can't handle this
well, they only keep
one space.

<snip>

I need these column to close specific shares with smbcontrol, but fail to
capture them. Is there any alternative?

Regards
-David

That's the node number. If you connect to another node, that
number will change.

Not really, sorry. You might want to send a patch to
smbstatus that makes the output machine-parseable.

awk can handle this, but I like sed. You may try this sed one liner.

smbstatus -S 2>/dev/null |sed -ne 's/^\(.*[[:alnum:]]\)[[:space:]]\{1,
\}\([[:digit:]]\{1,2\}\:[[:digit:]]\{1,20\}\)[[:space:]]\{1,\}\([[:alnum:]]*\)
[[:space:]]\{1,\}\(.*\)$/\1_ at _\2_ at _\3_ at _\4/p'

It only works for ctdb. You may change _ at _ with another delimeter like \t or 
\; ;-) .
