       To  analyze  a  binary  log file using standard tools, you must first convert it to ASCII. traffic_logcat
       does exactly that.

-oPATH,--output_filePATH

       Specifies where the command output is directed.

       -a,--auto_filename

       Automatically generates the output filename based on the input filename. If the input is from stdin, then
       this option is ignored.  For example:

          traffic_logcat -a squid-1.blog squid-2.blog squid-3.blog

       generates:

          squid-1.log squid-2.log squid-3.log

       -f,--follow

       Follows the file, like tail(1)-f-C,--clf

       Attempts to transform the input to Netscape Common format, if possible.

       -E,--elf

       Attempts to transform the input to Netscape Extended format, if possible.

       -S,--squid

       Attempts to transform the input to Squid format, if possible.

       -2,--elf2

       Attempt to transform the input to Netscape Extended-2 format, if possible.

       -T,--debug_tags-w,--overwrite_output-h,--help
              Print usage information and exit.

       -V,--version
              Print version information and exit.

       NOTE:
          Use only one of the following options at any given time: -S, -C, -E, or -2.

       If no input files are specified, then traffic_logcat reads from the standard input (stdin). If you do not
       specify an output file, then traffic_logcat writes to the standard output (stdout).

       For example, to convert a binary log file to an ASCII file, you can use the traffic_logcat  command  with
       either of the following options below:

          traffic_logcat binary_file > ascii_file
          traffic_logcat -o ascii_file binary_file

       The binary log file is not modified by this command.
