Nifty command line date and time utilities; fast date calculations and conversion in the shell
Arguments
| Name | Description |
|---|
FIRST | Date/time |
INCREMENT | |
LAST | Date/time |
Options
| Name | Description |
|---|
--help, -h | Print help and exit |
--version, -V | Print version and exit |
--quiet, -q | Suppress message about date/time and duration parse errors and fix-ups |
-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 <input format> | 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 |
-b, --base <base> | For underspecified input use DT as a fallback to fill in missing fields. Also used for ambiguous format specifiers to position their range on the absolute time line. Must be a date/time in ISO8601 format. If omitted defaults to the current date/time |
-e, --backslash-escapes | Enable interpretation of backslash escapes in the output and input format specifier strings |
--locale <locale> | Format results according to LOCALE, this would only affect month and weekday names |
-s, --skip <weekday...> | Skip weekdays specified by WEEKDAY. WEEKDAY can be a single weekday (Mon, Tue, etc.), and to skip several days the --skip option can be used multiple times. WEEKDAY can also be a comma-separated list of weekday names, or `ss' to skip weekends (sat+sun) altogether. WEEKDAY can also contain date ranges like `mo-we' for Monday to Wednesday |
--alt-inc <alternative increment> | Alternative increment to use when a date is hit that is skipped as per --skip. This increment will be applied until a non-skipped date is reached. The special case `0' (default) deactivates alternative incrementing. A useful value could be `1d' for increasing sequences and `-1d' for decreasing sequences, so if a skipped date is encountered the next non-skipped date after/before will be used |
--compute-from-last | Compute a start value from LAST using INCREMENT. This option has an effect only when INCREMENT is not a divisor of the duration between FIRST and LAST. In such case, an alternative FIRST will be computed by consecutively subtracting INCREMENT from LAST until FIRST is hit or crossed |
