SED / RegEx Puzzle

I have a file, with many of the log lines in like below example, what i'd like to do is basically add a CR after each piece of process information. I figured i'd do this with SED using the below

sed -rn 's/([0-9]+) \(([a-z._0-9]+)\) ([0-9]+) ([0-9]+)/ \2,\1,\3,\4 \n/gp' < file

This partially works, but I still get the Total: 3266 #015 from the log, which appears at the end of each line. I didn't expect this as it doesn't get matched in the regular expression.

I've tested the regular expression on the available websites, and they always look good, and find what i'd expect, its just when i combine with SED i don't quite get the result i was expecting.

Any help or suggestions would be most appreciated,

Thanks

Andy

This is a single line of the stats

Just remove the "Total:"

sed  -rn 's/ +Total:.*//;
          s/([0-9]+) +\(([a-z._0-9]+)\) +([0-9]+) +([0-9]+)/ \2,\1,\3,\4\n/gp'

You can also match the "Total:" optionally:

sed  -rn 's/([0-9]+) +\(([a-z._0-9]+)\) +([0-9]+) +([0-9]+)( *Total:.*)?/ \2,\1,\3,\4\n/gp'
#                                                          ------------^
