Hello, hoping someone can help. I'm looking to get a few scripts off the ground to help me with a laborious "log" culling, but my knowledge is a bit limited regarding perl and so am learning as I go. I had been experimenting with grep and while loops e.g. 
while (<IN>) {
  if (m/Server*Example/ig) {
    print OUT $_, "\n";
    print $_;
  }
}

But had been falling short on how to specify each specific part. Out of all the log files I would ideally love to extract the following snippets - System, Box, ByteIn, Bytesout, Description From the log example below the data would be: 
System : system001-server
Box    : HW a2b 1234Mb 123.4, address is 0012.d345.1234 (abc 0012.d123
+.4567)
ByteIn    : 3385567095904
Byteout  : 5816943852464
Description : example_system_server_example

Once the file data had been extracted from the .txt file --> output to a new CSV format file so I could read it into spreadsheets, example - System Box ByteIn Byteout Description: 
system001-server,HW a2b 1234Mb 123.4, address is 0012.d345.1234 (abc 0
+012.d123.4567),3385567095904,5816943852464,example_system_server_exam

This would be the ideal outcome, any help in how to do this properly would be_VERY_ much appreciated. Cas.
