特定の日付と場所の日の出と日没の時間と月と惑星のデータを表示するための簡単なオープンソースのコマンドラインプログラムはありますか？
Debian パッケージデータベースを閲覧し、Google で検索しても関連項目が見つかりません。これは私を驚かせます。天文学のオタクとUnixオタクの数を考えると、私は事実上の標準sunrise(1)（またはおそらくsunrise(6)）を期待したでしょう。
私は、空地図（celestia、kstars、starplot、stellarium）、地球地図（sunclock、xplanet）、カレンダー/議題（emacs、Remember）、時計（glunarclock、wmsun）など、偶然に計算を実行するより複雑なプログラムに興味があります。ありません。 ) ) 、朝夕年鑑(xtide)。たぶんあるかもしれませんaa（天文年鑑）、しかし、この経度と緯度で、この日に太陽が何時に浮かぶかを尋ねる簡単な方法はありません。
私が逃したものは何ですか？

試してみましたsunwaitか？
Sunwaitは、日の出と日没だけでなく、民間、海上、天文学の夕暮れを計算するために使用される小さなCプログラムです。 [..]

$ ./sunwait help
Calculate sunrise and sunset times for the current or targetted day.
The times can be adjusted either for twilight or fixed durations.
The program can either: wait for sunrise or sunset (function: wait),
or return the time (GMT or local) the event occurs (function: list),
or report the day length and twilight timings (function: report),
or simply report if it is DAY or NIGHT (function: poll).
You should specify the latitude and longitude of your target location.
Usage: sunwait [major options] [minor options] [twilight type] [rise|set] [offset] [latitude] [longitude]
Major options, either:
poll Returns immediately indicating DAY or NIGHT. See 'program exit codes'. Default.
wait Sleep until specified event occurs. Else exit immediate.
list [X] Report twilight times for next 'X' days (inclusive). Default: 1.
report Generate a report about the days sunrise and sunset timings.
Minor options, any of:
[no]debug Print extra info and returns in one minute. Default: nodebug.
[no]version Print the version number. Default: noversion.
[no]help Print this help. Default: nohelp.
[no]gmt Print times in GMT or local-time. Default: nogmt.
Twilight types, either:
daylight Top of sun just below the horizon. Default.
civil Civil Twilight. -6 degrees below horizon.
nautical Nautical twilight. -12 degrees below horizon.
astronomical Astronomical twilight. -18 degrees below horizon.
angle [X.XX] User-specified twilight-angle (degrees). Default: 0.
Sunrise/sunset. Only useful with major-options: 'wait' and 'list'. Any of: (default: both)
rise Wait for the sun to rise past specified twilight & offset.
set Wait for the sun to set past specified twilight & offset.
Offset:
offset [MM|HH:MM] Time interval (+ve towards noon) to adjust twilight calculation.
Target date. Only useful with major-options: 'report' or 'list'. Default: today
d [DD] Set the target Day-of-Month to calculate for. 1 to 31.
m [MM] Set the target Month to calculate for. 1 to 12.
y [YYYY] Set the target Year to calculate for. 2000 to 2099.
latitude/longitude coordinates: floating-point degrees, with [NESW] appended. Default: Bingham, England.
Exit (return) codes:
0 OK: exit from 'wait' or 'list' only.
1 Error.
2 Exit from 'poll': it is DAY or twilight.
3 Exit from 'poll': it is NIGHT (after twilight).
Example 1: sunwait wait rise offset -1:15:10 51.477932N 0.000000E
Wait until 1 hour 15 minutes 10 secs before the sun rises in Greenwich, London.
Example 2: sunwait list 7 civil 55.752163N 37.617524E
List civil sunrise and sunset times for today and next 6 days. Moscow.
Example 3: sunwait poll exit angle 10 54.897786N -1.517536E
Indicate by program exit-code if is Day or Night using a custom twilight angle of 10 degrees above horizon. Washington, UK.
Example 4: sunwait list 7 gmt sunrise angle 3
List next 7 days sunrise times, custom +3 degree twilight angle, default location.
Uses GMT; as any change in daylight saving over the specified period is not considered.
Note that program uses C library functions to determine time and localtime.
Error for timings are estimated at: +/- 4 minutes.
