Hello All,

I have a batch file that does two things and it works but on a 9GB file, it takes forever. Does anyone have any ideas how i can improve this from a batch file? Currently using cut, grep, awk, sed from GNU.

The %File_IN% is a 9GB server log where i want to end up with two new files.

%Results_COUNT% is the first file with a count of each log using the class file name

Code: Select all

     85  com.platform.mdm.core.identity.impl.EnterpriseIdentitySyncService 
      1  com.platform.mdm.tcp.client.InProcessMethodInvocationInitiatedTcpTunnelInstanceHandler 
2058567  com.platform.mdm.tcp.messaging.WorkflowBasedIncomingMessageRouterFactory 
    630  com.platform.transaction.TransactionImpl 
    630  com.platform.workflow.io.AbstractLinkOutputSource

%Results_ALL_New% is the second file(s) with all all the raw loglines from %File_IN% that match the patern like com.platform.mdm.tcp.messaging.WorkflowBasedIncomingMessageRouterFactory

Batch file

Code: Select all

echo Get a count of each log line and add results to file
echo.
cut -f6 -d"-" %File_IN% | sort | uniq -c > %Results_COUNT%
Echo Done!
echo.

Echo Done!
echo.

On files that big, it might fasten up the speed if you avoid pipes, writing intermediate results to temporary files.
In addition you should create a result file for the command processed by "for/f" and work on that instead of the command output.

AH, thanks for the help. The first part of the script is done and its dropped the time from 24 hours to ~13 mins. Starting to work on the second part now but let me know if you see any room for improvement? increasing sort above -S 1G does not seem to do anything even-though i have 8GB memory available. also, --parallel=xx does not seem available in GnuWin.

Results:

If split.exe (with -l option) is part of your gnuwin tools, then you could split the big file to smaller parts (and merge the resulting files with another for/f loop adding the integers), so sort would speed up:
But it depends on the algorithm of the gnuwin sort.exe if that will help speeding up your code.

Thanks, its available in GnuWin32

Code: Select all

C:\Tools>split.exe --help
Usage: split.exe [OPTION] [INPUT [PREFIX]]
Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, ...; default
size is 1000 lines, and default PREFIX is `x'.  With no INPUT, or when INPUT
is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
  -a, --suffix-length=N   use suffixes of length N (default 2)
  -b, --bytes=SIZE        put SIZE bytes per output file
  -C, --line-bytes=SIZE   put at most SIZE bytes of lines per output file
  -d, --numeric-suffixes  use numeric suffixes instead of alphabetic
  -l, --lines=NUMBER      put NUMBER lines per output file
      --verbose           print a diagnostic to standard error just
                            before each output file is opened
      --help     display this help and exit
      --version  output version information and exit

SIZE may have a multiplier suffix: b for 512, k for 1K, m for 1 Meg.
