1Usage: dateseq [OPTION]... FIRST [[INCREMENT] LAST] 2 3Generate a sequence of date/times from FIRST to LAST, optionally in steps of 4INCREMENT (which defaults to `1d'). 5 6If LAST is omitted it defaults to `now' if FIRST is a date/time, or `today' if 7FIRST is a date, or `time' if FIRST is a time. 8 9The values of FIRST and LAST are always inclusive and no date/times before 10FIRST and no date/times after LAST will be printed. 11 12Negative INCREMENTs must be given, i.e. if FIRST is newer than LAST. 13 14 -h, --help Print help and exit 15 -V, --version Print version and exit 16 -q, --quiet Suppress message about date/time and duration 17 parser errors and fix-ups. 18 The default is to print a warning or the 19 fixed up value and return error code 2. 20 -f, --format=STRING Output format. This can either be a specifier 21 string (similar to strftime()'s FMT) or the name 22 of a calendar. 23 -i, --input-format=STRING... Input format, can be used multiple times. 24 Each date/time will be passed to the input 25 format parsers in the order they are given, if a 26 date/time can be read successfully with a given 27 input format specifier string, that value will 28 be used. 29 -b, --base=DT For underspecified input use DT as a fallback to 30 fill in missing fields. Also used for ambiguous 31 format specifiers to position their range on the 32 absolute time line. 33 Must be a date/time in ISO8601 format. 34 If omitted defaults to the current date/time. 35 -e, --backslash-escapes Enable interpretation of backslash escapes in the 36 output and input format specifier strings. 37 --locale=LOCALE Format results according to LOCALE, this would only 38 affect month and weekday names. 39 --from-locale=LOCALE Interpret dates on stdin or the command line as 40 coming from the locale LOCALE, this would only 41 affect month and weekday names as input formats 42 have to be specified explicitly. 43 -s, --skip=STRING... Skip weekdays specified by STRING. 44 STRING can be a single weekday (Mon, Tue, etc.), 45 and to skip several days the --skip option can 46 be used multiple times. 47 STRING can also be a comma-separated list of 48 weekday names, or `ss' to skip weekends 49 (sat+sun) altogether. 50 STRING can also contain date ranges like `mo-we' 51 for monday to wednesday. 52 --alt-inc=STRING Alternative increment to use when a date is hit 53 that is skipped as per --skip. 54 This increment will be applied until a 55 non-skipped date is reached. 56 The special case `0' (default) deactivates 57 alternative incrementing. A useful value could 58 be `1d' for increasing sequences and `-1d' for 59 decreasing sequences, so if a skipped date is 60 encountered the next non-skipped date 61 after/before will be used. 62 --compute-from-last Compute a start value from LAST using INCREMENT. 63 This option has an effect only when INCREMENT is 64 not a divisor of the duration between FIRST and 65 LAST. In such case, an alternative FIRST will 66 be computed by consecutively subtracting 67 INCREMENT from LAST until FIRST is hit or 68 crossed. 69
