Details:

Hi,

 Not sure if this is a bug or just pilot error -

In section "5.1       The frm_xfrd Configuration directives" of the frm
manual (see Andy I do occasionally read the manuals ;-) )

The follow var's are referenced -

var:     $CID | $CGI | $DST | $INS | $LFN | $PFN | $RFN |
 
         $NOTIFY | $MDP | $OFLAG | $PRTY | $RID | $SRC |
 
         $USER | $eVar
 
Though later in the manual under the section -
These variables (and others) are referenced.

$RID            request identifier.
$SRC           the source file name. This may be $PFN or $RFN, depending on
the transfer direction. It may also be a url for url-based copy commands.
$TID            original requesting client’s trace identification.
$eVar            any variable that has been passed along with the file name
as          opaque information (i.e., contained in $CGI).

-------
Here is the frm.xfr.copycmd from my config file. 

frm.xfr.copycmd in stats noalloc /etc/xrootd/new-stagein.sh $SRC $DST $CID
$USER $TID

Here is how I handle the variables in new-stagein,sh

local_svr=`/bin/hostname`:${xrdport}
lfn=`echo $1 | /usr/bin/tr -d [:blank:]`
pfn=`echo $2 | /usr/bin/tr -d [:blank:]`
cid=$3
user=$4
tid=$5

Here what I see in a log file created when running the stagein script :

lfn:
/atlas/local/dbenjamin/data12_8TeV.00212809.physics_Egamma.merge.AOD.f481_m1233/data12_8TeV.00212809.physics_Egamma.merge.AOD.f481_m1233._lb0276._0001.1

user: $USER
tid: manager.0:26@aschead02

-------------

I am trying to capture the user name who triggered the frm transfer so that I
can save that information with the extended attributes of the file.

Thanks.
