weather(1) General Commands Manual weather(1) NAME weather - command-line tool to obtain weather conditions and forecasts SYNOPSIS weather [ options ] [ alias1 | search1 [ alias2 | search2 [...]]] DESCRIPTION This command-line utility is intended to provide quick access to cur- rent weather conditions and forecasts. Presently, it is capable of re- turning data for localities throughout the USA and some select loca- tions globally by retrieving and formatting decoded METARs (Meteorolog- ical Aerodrome Reports) from NOAA (the USA National Oceanic and Atmos- pheric Administration) and forecasts/alerts from NWS (the USA National Weather Service). The tool is written to function in the same spirit as other command-line informational utilities like cal(1), calendar(1) and dict(1). It retrieves arbitrary weather data via precompiled cor- relations or custom-tailored aliases (system-wide or on a per-user ba- sis). Behavior can be determined by command-line options and specification of zero or more location aliases and search terms. Aliases are defined in weatherrc(5) files, as a convenient means of grouping URIs together using a short name. Specifying multiple aliases or location search terms on the command line causes the utility to out- put data for each, as if it had been invoked multiple times. If none are specified, then an alias of default is checked for a defargs option and any alias names listed within it (comma-separated) are applied in- stead. Searches utilize location correlation sets in INI-style text files named airports, places, stations, zctas and zones. A precomputed copy is distributed with the source, but can be rebuilt from updated data sources as needed by placing them in the current working directory and running with the --build-sets option (see the comments at the top of any location correlation set file for instructions on where to find up- dated data sources). Positive search results are cached and sourced as aliases on subsequent runs for as long as the correlation sets remain unchanged, and are cleared automatically once the correlation sets are updated. Retrieved data is also cached automatically for a short period of time, adjustable with the cacheage configuration option or --cacheage com- mand-line option. This helps throttle load against NOAA/NWS servers in case the utility is repeatedly re-run requesting the same data, but can be overridden with the cache_data configuration option or --no-cache-data command-line option. OPTIONS A summary of options is included below. --version show program's version number and exit -h, --help show a help message and exit -a, --alert include local alert notices --atypes=ATYPES list of alert notification types to display (ex: tornado,ur- gent_weather_message) --build-sets (re)build location correlation sets --cacheage=CACHEAGE duration in seconds to refresh cached data (ex: 900) --cachedir=CACHEDIR directory for storing cached searches and data (ex: ~/.weather) -f, --forecast include a local forecast --headers=HEADERS list of conditions headers to display (ex: temperature,wind) --imperial filter/convert conditions for US/UK units --info output detailed information for your search -l, --list list all configured aliases and cached searches --longlist display details of all configured aliases -m, --metric filter/convert conditions for metric units -n, --no-conditions disable output of current conditions --no-cache disable all caching (searches and data) --no-cache-data disable retrieved data caching --no-cache-search disable search result caching -q, --quiet skip preambles and don't indent --setpath=SETPATH directory search path for correlation sets (ex: .:~/.weather) -v, --verbose show full decoded feeds EXAMPLES weather View output for the default alias, if one has been defined (oth- erwise display usage/syntax similar to --help) weather rdu Display weather conditions at the airport with IATA/FAA code RDU. weather --info raleigh Show a list of FIPS codes for United States Census Bureau places containing the word raleigh (or the proximity information if only one match was found). weather "^ral[ie]{2}gh city.*nc$" Get the current weather conditions from the nearest station to the Census place name matching the regular expression provided. weather -fv fips3755000 Get the full decoded METAR from the nearest station, and the forecast data for the nearest zone to the Census place with FIPS code 3755000 with no special filtering or formatting. weather --forecast --no-cache-data 27613 Ignore any recent cached METAR or forecast data and display fresh output for the nearest station and zone to the Census ZCTA (essentially USPS ZIP code) 27613. weather home work Show current conditions for both the home and work aliases in that order. weather 35.878573,-78.727813 weather 35-52-43n,78-43-40w weather "35-52n, 78-43w" Display weather conditions for the nearest station to an arbi- trary set of global coordinates in latitude,longitude order ei- ther in decimal format or degree, degree-minute or de- gree-minute-second formats, optionally using signed or cardinal hemisphere designations with or without spacing. Note that the cut-off for maximum acceptable distance is hard-coded at 0.1 ra- dians (roughly 637km or 396mi). INPUT FILES weather may additionally obtain configuration data from a system-wide configuration file, a per-user configuration file, and a local direc- tory configuration file. The file format and configuration options are described in weatherrc(5). They are aggregated in the following order: /etc/weatherrc or /etc/weather/weatherrc the system-wide configuration ~/.weather/weatherrc or ~/.weatherrc the per-user configuration ./weatherrc the local directory configuration AUTHOR Utility and manual written by Jeremy Stanley <fungi@yuggoth.org>.
