       cronosplit - split log files into cronolog-compatible files


       cronosplit --template=TEMPLATE [--print-invalid] [--help] [--version] file ...


       cronosplit  is a simple program that reads lines from a set of input log files, which must
       be in Common Log Format or NCSA Combined/XLF/ELF Format and write each lines to an  output
       files,  the  name  of which is constructed using the template specified and timestamp from
       the the line.  The template uses the same format specifiers as the  Unix  date(1)  command
       (which are the same as the standard C strftime library function).


       cronosplit accepts the following options and arguments:

              specifies  the  template  for  the  output  log  files (using the format specifiers
              described below).

              print invalid log file entries to the standard error stream.

              update modification time of output file according to last parsed log entry.

              print additional status messages to the standard error stream.

              print debug messages to the standard error stream.

       --help print a help message and then exit.

              print version information and exit.

Template format

       Each character in the template represents a character in the expanded filename, except for
       date and time format specifiers, which are replaced by their expansion.  Format specifiers
       consist of a `%' followed by one of the following characters:

       %      a literal % character

       n      a new-line character

       t      a horizontal tab character

       Time fields:

       H      hour (00..23)

       I      hour (01..12)

       p      the locale's AM or PM indicator

       M      minute (00..59)

       S      second (00..61, which allows for leap seconds)

       X      the locale's time representation (e.g.: "15:12:47")

       Z      time zone (e.g. GMT), or nothing if the time zone cannot be determined

       Date fields:

       a      the locale's abbreviated weekday name (e.g.: Sun..Sat)

       A      the locale's full weekday name (e.g.: Sunday .. Saturday)

       b      the locale's abbreviated month name (e.g.: Jan .. Dec)

       B      the locale's full month name, (e.g.: January .. December)

       c      the locale's date and time (e.g.: "Sun Dec 15 14:12:47 GMT 1996")

       d      day of month (01 .. 31)

       j      day of year (001 .. 366)

       m      month (01 .. 12)

       U      week of the year with Sunday as first day of week (00..53, where week 1 is the week
              containing the first Sunday of the year)

       W      week of the year with Monday as first day of week (00..53, where week 1 is the week
              containing the first Monday of the year)

       w      day of week (0 .. 6, where 0 corresponds to Sunday)

       x      locale's date representation (e.g. today in Britain: "12/04/96")

       y      year without the century (00 .. 99)

       Y      year with the century (1970 .. 2038)

       Other specifiers may be available depending on  the  C  library's  implementation  of  the
       strftime function.
