Ooops, missing an END.
Sorry, my bad. :)

Hi Terry,
I was just catching up on some old posts to the list, so you've probably
already resolved this - but I thought I'd let you know a much better way
of doing this:
/*Query if a virtual machine is logged on and exit on CP QUERY USER RC*/
Trace Off /*No need to
trace*/
Address Command /*Always better
than ADDRESS CMS*/
Parse Upper Arg LinuxGuest . /*Get the name of
the target virtual machine*/
If LinuxGuest='' Then Do
Say 'You did not provide the name of a VM to query.'
Exit 45 /*Same RC as CP
QUERY USER will yield for user not logged on*/
End
'PIPE CP QUERY USER' LinuxGuest '| HOLE' /*Is the user
logged on?*/
If Rc=0 Then Say LinuxGuest 'is logged on.' /*RC0=Yes*/
Else Say LinuxGuest 'is not logged on.' /*RC45=No*/
Exit Rc /*Exit on CP QUERY
USER RC, in case we are called by another program*/
Invoke with your "guest" as an argument, so for example if you named
this exec QLINUX and wanted to query LINUX1, you'd execute it as:
QLINUX LINUX1
Once you get familiar with the various commands and return codes
available, you'll find it helps quite a bit to simply check RC's from
commands. :)

Hi
In the pipe command below where GUEST is the name of a Linux that I
PULLED from a previous SAY. I want to use GUEST in the LOCATE can I do
this and if so is the syntax correct? I have tried this but it does not
work unless I put a specific Linux name in the LOCATE. This is just a
test EXEC while I get a feel for all of this.
SAY 'LINUX GUEST ID'
PULL GUEST
'PIPE CP Q NAMES | LOCATE /GUEST/ | SPLIT | LOCATE /GUEST/',
'| > LINUX USERS A'
USERID = 'LINUX USERS A'
PARSE VALUE STREAM(USERID,'C','OPEN READ') WITH OK FILE_HANDLE
IF OK /= 'READY:' THEN
DO
SAY 'NO LINUX USERS LOGGED ON'
END
'CP I CMS'
EXIT /* RETURN TO CMS */
Thank You,
