Parse input from stdin according to one of the given formats formats.
strptime [OPTION]... [INPUT]...
Parse input from stdin according to one of the given formats FORMATs. The format string specifiers are the same as for strptime(3).
Recognized OPTIONs:
-h, --help
Print help and exit
-V, --version
Print version and exit
-t, --time
also display time in the output, default is to display the date
-q, --quiet
Suppress message about date/time and duration parser errors.
-f, --format=STRING
Output format. This can either be a specifier string (similar to strftime()'s FMT) or the name of a calendar.
-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.
-e, --backslash-escapes
Enable interpretation of backslash escapes in the output and input format specifier strings.
-S, --sed-mode
Copy parts from the input before and after a matching date/time. Note that all occurrences of date/times within a line will be processed.
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.
$ strptime -i '%a, %b-%d/%Y' 'Mon, May-01/2000' 2000-05-01 $
$ strptime -i '%a, %b-%d/%Y' <<EOF Mon, May-01/2000 Mon, Mar-2/2000 EOF 2000-05-01 2000-03-02 $
