NAME

       dsort - Sort contents of FILE chronologically.

SYNOPSIS

       dsort [OPTION]... [FILE]...

DESCRIPTION

       Sort contents of FILE chronologically.  If FILE is omitted read from stdin.

       The first date/time value per line is the sort key.  Dates without times account for a smaller value than
       any date/time on the same day.  Times without dates  account  for  a  smaller  value  than  any  date  or
       date/time.  If a line contains no dates or times or date/times it is sorted towards the front.

       Recognized OPTIONs:

       -h, --help
              Print help and exit

       -V, --version
              Print version and exit

       -i, --input-format=STRING...
              Input  format,  can  be  used  multiple  times.  Each date/time will be passed to the input format
              parsers in the order they are given, if a date/time can be read successfully with  a  given  input
              format specifier string, that value will be used.

       --default=DT
              For  underspecified  input use DT as a fallback to fill in missing fields.  Must be a date/time in
              ISO8601 format.  If omitted the default value is the current date/time.

       -e, --backslash-escapes
              Enable interpretation of backslash escapes in the input format specifier strings.

       --from-zone=ZONE
              Interpret dates on stdin or the command line as coming from the time zone ZONE.

       -r, --reverse
              Reverse the sort order.

       -u, --unique
              Print at most one line per date/time value.

FORMAT SPECS

       Format specs in dateutils are similar to posix' strftime().

       However, due to a broader range of supported calendars dateutils must employ different rules.

       Date specs:
         %a  The abbreviated weekday name
         %A  The full weekday name
         %_a The weekday name shortened to a single character (MTWRFAS)
         %b  The abbreviated month name
         %B  The full month name
         %_b The month name shortened to a single character (FGHJKMNQUVXZ)
         %c  The count of the weekday within the month (range 00 to 05)
         %C  The count of the weekday within the year (range 00 to 53)
         %d  The day of the month, 2 digits (range 00 to 31)
         %D  The day of the year, 3 digits (range 000 to 366)
         %F  Equivalent to %Y-%m-%d (ymd's canonical format)
         %j  Equivalent to %D
         %m  The month in the current calendar (range 00 to 19)
         %Q  The quarter of the year (range Q1 to Q4)
         %q  The number of the quarter (range 01 to 04)
         %s  The number of seconds since the Epoch.
         %u  The weekday as number (range 01 to 07, Sunday being 07)
         %U  The week count,  day of week is Sun (range 00 to 53)
         %V  The ISO week count,  day of week is Mon (range 01 to 53)
         %w  The weekday as number (range 00 to 06, Sunday being 00)
         %W  The week count,  day of week is Mon (range 00 to 53)
         %y  The year without a century (range 00 to 99)
         %Y  The year including the century
         %Z  The zone offset in hours and minutes (HH:MM) with
             a preceding sign (+ for offsets east of UTC, - for offsets
             west of UTC)

         %Od The day as roman numerals
         %Om The month as roman numerals
         %Oy The two digit year as roman numerals
         %OY The year including the century as roman numerals

         %rs In time systems whose Epoch is different from the unix Epoch, this
             selects the number of seconds since then.
         %rY In calendars with years that don't coincide with the Gregorian
             years, this selects the calendar's year.

         %dth  The day of the month as an ordinal number, 1st, 2nd, 3rd, etc.
         %mth  The month of the year as an ordinal number, 1st, 2nd, 3rd, etc.

         %db The business day of the month (since last month's ultimo)
         %dB Number of business days until this month's ultimo

       Time specs:
         %H  The hour of the day using a 24h clock, 2 digits (range 00 to 23)
         %I  The hour of the day using a 12h clock, 2 digits (range 01 to 12)
         %M  The minute (range 00 to 59)
         %N  The nanoseconds (range 000000000 to 999999999)
         %p  The string AM or PM, noon is PM and midnight is AM.
         %P  Like %p but in lowercase
         %S  The  (range 00 to 60, 60 is for leap seconds)
         %T  Equivalent to %H:%M:%S

       General specs:
         %n  A newline character
         %t  A tab character
         %%  A literal % character

       Modifiers:
         %O  Modifier to turn decimal numbers into Roman numerals
         %r  Modifier to turn units into real units
         th  Suffix, read and print ordinal numbers
         b   Suffix, treat days as business days

       By design dates before 1601-01-01 are not supported.

       For conformity here is a list of calendar designators and their corresponding format string:
         ymd     %Y-%m-%d
         ymcw    %Y-%m-%c-%w
         ywd     %rY-W%V-%u
         bizda   %Y-%m-%db
         lilian     n/a
         ldn        n/a
         julian     n/a
         jdn        n/a

       These  designators  can  be  used  as  output  format  string,  moreover,  @code{lilian}/@code{ldn}   and
       @code{julian}/@code{jdn} can also be used as input format string.
