tirwhan,


I'm sorry. The question I meant to ask was as
follows:


The 3 CSV files which I am using as input do not have
identical server names.


File A
Server,Avg CPU,P95 CPU,Avg Mem Util,P95 Mem Util
WSOMQAVPRA05,93.75,95.87,66.67,68.13
wsomdavpra03,90.39,94,65.77,68.51
wsomddvfxa01,39.22,92.19,82.59,88.25


File B
Server,Avg CPU,P95 CPU,Avg Mem Util,P95 Mem Util
WSOMQAVPRA05,34.78,100,55.1,67.6
wsomdavpra03,69.04,98.55,84.07,89.73
wsomddvfxa01,92.44,97.54,67.72,71.69
wsompapgtw05,48.77,96.9,92.1,93.55


File C
Server,Avg CPU,P95 CPU,Avg Mem Util,P95 Mem Util
WSOMQAVPRA05,93.13,98.11,68.95,73.47
wsomdavpra03,68.85,97.56,76.35,98.23
wsomddvfxa01,46.97,96.29,88.23,94.02
wsompapgtw05,30.66,93.74,39.89,71.35


What I am trying to do is for each Server (in Column
1) I want to get the Avg CPU (in Column 2) from each
of the 3 files. In the files above this would produce


File OUT
WSOMQAVPRA05,93.75,34.78,93.13
wsomdavpra03,90.39,69.04,68.85
wsomddvfxa01,39.22,92.44,46.97
wsompapgtw05,0,48.77,30.66


Notice in File OUT for Server Name (wsompapgtw05),
since wsompapgtw05 does not appear in File A, the
value is replaced with '0'. How can I get perl to
place a '0' in the output file when a particular
server name appears in at least 1 of the input files,
but not in all of the input files?
