NAME

cronosplit - split log files into cronolog-compatible files

SYNOPSIS

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

DESCRIPTION

cronosplit is a simple program that reads lines from a set of input log files, which must be in Common Log 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).

Options

accepts the following options and arguments:

--template=TEMPLATE: specifies the template for the output log files (using the format specifiers described below).
--verbose: print additional status messages to the standard error stream.
--debug: print debug messages to the standard error stream.
--help: print a help message and then exit.
--version: 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.
