cronosplit - split log files into cronolog-compatible files
--template=TEMPLATE [--print-invalid] [--help] [--version]
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
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
command (which are the same as the standard C strftime library function).
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
- update modification time of output file according to last
parsed log entry.
- print additional status messages to the standard error
- print debug messages to the standard error stream.
- print a help message and then exit.
- print version information and exit.
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
- a literal % character
- a new-line character
- a horizontal tab character
- hour (00..23)
- hour (01..12)
- the locale's AM or PM indicator
- minute (00..59)
- second (00..61, which allows for leap seconds)
- the locale's time representation (e.g.:
- time zone (e.g. GMT), or nothing if the time zone cannot be
- the locale's abbreviated weekday name (e.g.: Sun..Sat)
- the locale's full weekday name (e.g.: Sunday ..
- the locale's abbreviated month name (e.g.: Jan .. Dec)
- the locale's full month name, (e.g.: January ..
- the locale's date and time (e.g.: "Sun Dec 15 14:12:47
- day of month (01 .. 31)
- day of year (001 .. 366)
- month (01 .. 12)
- 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)
- 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)
- day of week (0 .. 6, where 0 corresponds to Sunday)
- locale's date representation (e.g. today in Britain:
- year without the century (00 .. 99)
- year with the century (1970 .. 2038)
Other specifiers may be available depending on the C library's implementation of
