NAME

lcg_util - Python interface to the LCG_UTIL  

SYNOPSIS

import lcg_util
from lcg_util import * not supported
 

DESCRIPTION

The util module permits you to access the lcg_util client interface from python programs. The util module is a swig wrapping of the standard C interface. For detailed descriptions of each function see the individual man page of each function.

There follows a series of examples of how to use selected functions and how to retrieve the information returned by them: Examples are to copy a file to SE and register it in replica catalog or lfc, finding the GUID for given surl or lfn, copy and register file from one SE to another, Unregister and register a file in LFC residing on an SE.

 

EXAMPLE

#!/usr/bin/python

"""
# Copy a file to Storage element and register in the the LFC.
"""

import sys
import lcg_util

src='file:/etc/hosts'
dest='grid2.irb.hr'
guid="212fa800-9d65-11da-a746-0800200c9b13"
lfn='/grid/dteam/fnaz/testfile'
vo='dteam'
relativepath='fnaz/testfile'
nstreams=1
config=''
insecure=0
verbose=1
actual_guid=""
for i in range(0,37):
        actual_guid=actual_guid + " "

output= lcg_util.lcg_cr(src,dest,guid,lfn,vo,relativepath,nstreams,'',insecure,verbose,actual_guid)
print "teststatus: ",output
print "actual_guid: ",actual_guid
