Query Wikipedia via console over DNS

Query Wikipedia by issuing a DNS query for a TXT record. The TXT record will also include a short URL to the complete corresponding Wikipedia entry.You can also write a little shell script like:

$ cat wikisole.sh

#!/bin/sh

dig +short txt ${1}.wp.dg.cx

and run it like

./wikisole.sh unix

were your first option ($1) will be used as search term.

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives
mwiki() { dig +short txt "$*".wp.dg.cx; }

Shorter version, works with multiple words.

mwiki () { blah=`echo $@ | sed -e 's/ /_/g'`; dig +short txt $blah.wp.dg.cx; }
nslookup -q=txt <topic>.wp.dg.cx
mwiki () { dig +short txt `echo $*|sed 's| *|_|g'`.wp.dg.cx; }
wiki() { local IFS=_; dig +short txt "${*^}".wp.dg.cx; }

this is awesomely wacky

Vote this up. One can feel the awesome behind this command :-)

Comment by Alanceil 265 weeks and 2 days ago

cute DNS abuse :)

Comment by penpen 265 weeks and 2 days ago

Very very cool.

Comment by qubyte 265 weeks and 2 days ago

We can add some GUI spice to teh absue :P , dep==> zenity

zenity --info --text="$(dig +short txt $(zenity --entry --title="Search wiki" --text="Enter your search word:").wp.dg.cx)"

Comment by hemanth 265 weeks and 1 day ago

This is simply awesome. In the shell script example, add quotes around the "${1}" and you can do multi-word searches using quotes in your arg, like:

./wikip.sh "gradient descent"
Comment by zombiedeity 264 weeks and 6 days ago

Script with prettified output:

cat wikisole.sh

#!/bin/sh

COLUMNS=`tput cols`

dig +short txt "${1}".wp.dg.cx | sed -e 's/" "//g' -e 's/^"//g' -e 's/"$//g' -e 's/ http:/\n\nhttp:/' | fmt -w $COLUMNS

Comment by philipsd6 264 weeks and 6 days ago

philipsd6's version as a function in bashrc:

function wiki () {

COLUMNS=`tput cols`

dig +short txt ${1}.wp.dg.cx | sed -e 's/" "//g' -e 's/^"//g' -e 's/"$//g' -e 's/ http:/\n\nhttp:/' | fmt -w $COLUMNS

}

Comment by bstaz 264 weeks and 6 days ago

You can also search for more than one word like this:

dig +short txt "multiple words".wp.dg.cx

I wrote a wrapper script that takes either 1 word or multiple words and formulates the syntax properly:

#!/bin/bash

function help {

echo -e "\n\tusage: $0 "

exit

}

if [ -z "$1" ]; then

help

fi

while [ "$1" != "" ]; do

if [ "$SEARCH" = "" ]; then

SEARCH="$1"

else

SEARCH="$SEARCH $1"

fi

shift

done

echo -e "\n\tLooking up $SEARCH\n"

dig +short txt "$SEARCH".wp.dg.cx

echo ""

Comment by omish_man 264 weeks and 6 days ago

I hate dig.

Why not use:

host -t txt linux.wp.dg.cx
Comment by vutcovici 264 weeks and 4 days ago

Simpler multiple words fix:

dig +short txt "`echo $@`".wp.dg.cx

Comment by peter0081 260 weeks and 3 days ago
dig +short txt <keyword>.wp.dg.cx | espeak
Comment by matthewbauer 258 weeks and 2 days ago

I wonder if we can do that with French language ( fr.wikipedia.org )

Like with this example : fr.wikipedia.org/wiki/Tse

Comment by sputnick 244 weeks ago
mwiki () { echo $@ > foo; blah=`sed 's/ /_/g' foo`; dig +short txt $blah.wp.dg.cx; }

Sample output:

mwiki snow leopard

"The snow leopard (Uncia uncia or Panthera uncia), sometimes known as \"ounce,\" is a moderately large cat native to the mountain ranges of Central Asia. The classification of this species has been subject to change and its exact taxonomic position is still " "unclear.

#! /bin/bash

echo please input your subject

read SUBJECT

dig +short txt SUBJECT.wp.dg.cx

Comment by ethnopunk 232 weeks and 3 days ago

Shorter version, works with multiple words:

mwiki() { dig +short txt "$*".wp.dg.cx; }

Comment by dorin 231 weeks and 2 days ago

on windows:

nslookup -q=txt shit.wp.dg.cx
Comment by unixmonkey9108 230 weeks and 5 days ago

"slookup -q=txt" does not appear to be valid (i have WinXP+SP3)...

Comment by bugmenot 210 weeks and 6 days ago

sorry, in mean "Nslookup -q=txt"...

Comment by bugmenot 210 weeks and 6 days ago

Nice. These dns lookups seems faster than an actual http request.

But I don't like the disturbing " and \ and the missing linebreaks. Therefore by combining dorin's ID with a sed and fmt I get to:

mwiki() { dig +short txt $(echo $* | sed 's/ /_/g').wp.dg.cx|sed -E "s/\" \"|^\"|\"$|\\\\//g"|fmt; }
Comment by unixmonkey12820 203 weeks and 2 days ago

what do you need this for?

has it some advantages to to such a query over DNS?

why can't you use curl instead?

Comment by rubo77 201 weeks and 6 days ago

how to convert the utf-8 encode result to itf-8?

e.g. when I query "Leon", I got "L\195\169on".

I tried to convert is using "echo -e", but echo only support \xC3\xA9 format.

Comment by hileon 107 weeks and 4 days ago

This command is great.

But when I run it now I get:

;; connection timed out; no servers could be reached

Anyone know what's wrong? I looks like Wikipedia is blocking dns requests or something else has changed.

Comment by JokesOnYou 82 weeks and 2 days ago

JokesOnYou ... not sure exactly but you can stipulate the nameserver to query as a swich to dig, ie (using opendns).

dig @resolver1.opendns.com +short txt "${1}".wp.dg.cx

Comment by khayyam 75 weeks and 3 days ago

But does this work?~

Comment by ohuhu 39 weeks and 5 days ago

I mean how does this work

Comment by ohuhu 39 weeks and 5 days ago

The guy who made it possible: https://dgl.cx/wikipedia-dns

@sputnick Like said in the link above, this is a special nameserver that returns a short description of the query. So the article language is handled at server side.
