GRIB_GET(1)

💖 GRIB_GET(1) 💖

hi bestie!! welcome to grib_get, a page from the User Commands section, manual name GRIB_GET(1). it's short, it's sweet, and it is so useful. grab a strawberry 🍓 and let's go.

✨ NAME ✨

grib_get — the manual page for grib_get 💅

---

🌸 DESCRIPTION 🌸

okay so real talk: this page contains its own NAME, DESCRIPTION, USAGE, OPTIONS and SEE ALSO sections nested inside its DESCRIPTION, and then prints the entire thing a second time. iconic of it, honestly 😭 — but you're getting the tea once, fully, with every single crumb preserved. no skips, no summarising, we don't do that here 🫶

🎀 NAME 🎀

grib_get

🦋 DESCRIPTION 🦋

Get values of some keys from a GRIB file. it's giving similar-to-grib_ls energy ✨ but here's the plot twist, and it's the whole point: grib_get fails returning an error code when an error occurs (e.g. when a key is not found). so like… grib_ls is the chill friend who lets it slide, and grib_get is the friend who will send it back to the group chat. that's the vibe. periodt 💅

✨ USAGE ✨

grib_get [options] grib_file grib_file ...

👑 OPTIONS 👑

one bullet per flag, every flag, in order, no cap:

• -f — Force. makes it not fail on error. the "no thoughts, just vibes, keep going" flag.
• -p key[:{s|d|i}],key[:{s|d|i}],... — declaration of keys to print 👑 for each key you can request a string (key:s), a double (key:d) or an integer (key:i) type. default type is string.
• -F format — C-style format for floating-point values. for when you want your numbers to serve a certain look ✨
• -B 'order by' directive — Order by. the output will be ordered according to the 'order by' directive. example: "step:i asc, centre desc" (that's step numeric ascending and centre descending, iykyk). default sort mode is 'asc'.
• -l latitude,longitude[,MODE,file] — value close to the point of a latitude,longitude (nearest neighbour). allowed values for MODE are:
  • 4 — 4 values in the nearest points are printed. default is 1 (the value at the nearest point is printed).
  • file — file is used as mask. the closer point with mask value >=0.5 is printed.
• -P key[:{s|d|i}],key[:{s|d|i}],... — same as -p, but it adds the declared keys to the default list. best of both worlds, we love a generous queen 💖
• -w key[:{s|d|i}]{=|!=}value,key[:{s|d|i}]{=|!=}value,... — Where clause. messages are processed only if they match all the key/value constraints. a valid constraint is of type key=value or key!=value. for each key a string (key:s), a double (key:d) or an integer (key:i) type can be specified. default type is string. in the value you can also use the forward-slash character / to specify an OR condition (i.e. a logical disjunction).

Note: only one -w clause is allowed. one. just one. that's the rule 🫠

• -n namespace — all the keys belonging to the given namespace are printed.
• -s key[:{s|d|i}]=value,key[:{s|d|i}]=value,... — key/values to set. for each key a string (key:s), a double (key:d) or an integer (key:i) type can be defined. by default the native type is set.
• -V — Print version. short flag, big "hi what's your name" energy 💁
• -W width — minimum width of each column in output. default is 10.
• -m — all the keys belonging to the 'mars' namespace are printed.
• -M — Multi-field support off. turns off support for multiple fields in a single GRIB message.
• -g — copy GTS header.
• -G — GRIBEX compatibility mode.
• -T T | B | A — Message type. T->GTS, B->BUFR, A->Any (Experimental). the input file is interpreted according to the message type.
• -7 — does not fail when the message has wrong length. chaotic but brave 🍓
• -X offset — input file offset in bytes. processing of the input file will start from the given offset.
• -i index — the data value corresponding to the given index is printed.
• -h — display this help text and exit. the "nvm, tell me" button 🙈
