NAME
strptime - Parse input from stdin according to one of the given formats FORMATs.
SYNOPSIS
strptime [OPTION]... [INPUT]...
DESCRIPTION
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.
-l, --locale
Make internal strptime(3) and strftime(3) behave in a locale dependent way, default is to pretend
LC_ALL=C is in place.
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)
%g ISO week date year without the century (range 00 to 99)
%G ISO week date year including the century
%j Equivalent to %D
%m The month in the current calendar (range 00 to 12)
%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
%_y The year shortened to a single digit
%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
%0 Modifier to turn on zero prefixes
%SPC Modifier to turn on space prefixes
%- Modifier to turn off prefixes altogether
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
matlab n/a
mdn 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.
EXAMPLES
$ strptime -i '%a, %b-%d/%Y' 'Mon, May-01/2000'

$ strptime -i '%a, %b-%d/%Y' <<EOF
Mon, May-01/2000
Mon, Mar-2/2000
