description:
  Get time-specific access to logfiles.

  logscan is able to handle rotated and/or gzipped logfiles or to read stdin.
  It supports several formats for time-information in the log, and checks the
  logfiles automatically for them. You can also specify further formats in
  logscan.conf.


positional argument:
  LOGFILE                   If LOGFILE is missing or '-' stdin is read instead.

optional arguments:
  -h, --help                print this help message and exit
  -i, --info                print the number of files, the start-time and end-time
  -c, --timecode TIMECODE   use TIMECODE to parse the log-times (e.g. "%Y-%m-%d %H:%M:%S")
  -g, --grep PATTERN        print only lines where PATTERN was found
  -d, --date DATE           print all log-entries of DATE

arguments for times:
  -d, --date DATE           print all log-entries of DATE
  -t, --time [DATE] TIME    specify a point of time; use it twice to specify
                            a start- and end-time

argruments for durations:
  -p, --plus [WEEKS] [DAYS] [HOURS] [MINUTES] [SECONDS]
  -m, --minus [WEEKS] [DAYS] [HOURS] [MINUTES] [SECONDS]


times (DATE and TIME):
  DATE and TIME could be in any format. Logscan tries hard to interpret the input
  as valid date or time.
  If DATE is omitted for --time logscan uses the date of the last log-entry.
  If DATE is incomplete logscan completes it with the year or the year and month
  of the actual date.


durations:
  To specify a positive duration use --plus, for a negative use --minus.
  All values are interpreted as weeks, days, hours, minutes or seconds -in this
  order starting with days. Alternatively you can flag the values with letters
  matching those keywords.
  So to specify a positive duration of 3 days and 4 minutes you can either do
  "--plus 3 0 4" or --plus 3d 4m.


Which period to print is defined as follows:
  no times and no duration:         from start to eof
  one time and no duration:         from time to eof
  two times and no duration:        from time-one to time-two
  no times and positive duration:   form start to end of duration
  no times and negative duration:   from begin of duration to eof
  one time and positive duration:   from time to end of duration
  one time and negative duration:   from begin of duration to time


time-code-formats:
  logscan checks a log-file automatically for these formats:
  %Y-%m-%d %H:%M:%S
  %b %d %X %Y
  %b %d %X
  %s
  Also a timestamp as total amount of seconds since epoche (1970-01-01 00:00:00 UTC)
  is supported. logscan expects for it a ten-digit decimal with three decimal-places.
  To specify further format-codes use logscan.conf. logscan uses either the first
  format that fits or an explicitly with --timecode given format.
  A list of all available format-codes can be recieved from 'date --help'.
