+
+The "lcg-info" command is similar to the "lcg-infosites" except that it is used to list either CE's or SEs satisfying a given set of conditions on their attributes and to print, for each of them, the values of a given set of attributes. 
+
+ 1. The first step is to view the list of attributes available for both the matching and printing aspects of ‘lcg-info’ :
+
+
+{{{
+lcg-info --list-attrs
+}}}
+
+
+ 1. "lcg-info"  is very similar to the usage of the "Requirements" tag in a JDL file along with the command "glite-job-list-match". The "lcg-info" command can therefore be useful when constructing the "Requirements" tag in a JDL file. Note that "lcg-info" does not in most (but not all) cases need a VO to be specified. 
+
+
+{{{
+lcg-info --vo vo.llr.in2p3.fr --list-ce --query 'Tag=MPICH' --attrs 'FreeCPUs,Tag'
+}}}
+
+ 1. "lcg-info" can also query the attributes of CE's and searches for the closest CE to the SE "polgrid4.in2p3.fr". 
+
+
+{{{
+lcg-info --list-se --query 'SE=polgrid4.in2p3.fr' --attrs CloseCE
+}}}
