How To Look Up Dictionary Definitions Via Terminal
|
||
================================================================================
|
||
Most people when they find a word they’re not familiar with, they Google it. Either that or they have a favorite online dictionary that provides an answer. What happens when you have no network connectivity? Or maybe you have an older distribution of Linux and you don’t have a GUI? You need to look it up offline. A good way to do that is here.
|
||
|
||
First you need to set up dictd locally. **Dictd** is a dictionary database server. It allows you to access online dictionaries. But wait, that’s what we wanted to avoid, right? A connection over the Internet. That’s why you set it up on localhost. It comes with a command-line client.
|
||
|
||
To install dictd on Ubuntu or Debian you type:
|
||
|
||
$ sudo apt-get install dictd
|
||
|
||
That was easy. Now you need to install dictionaries for it to use. After each dictionary addition dictd will automatically restart to reload its databases. Let’s say we want to install the English dictionary and an English thesaurus (look up synonyms).
|
||
|
||
Type:
|
||
|
||
$ sudo apt-get install dict-gcide
|
||
$ sudo apt-get install dict-moby-thesaurus
|
||
|
||
If you want another language you can check the other packages by typing:
|
||
|
||
$ sudo apt-cache search “dict package”
|
||
|
||
That will give you a list like:
|
||
|
||
dict-freedict-eng-ara - Dict package for English-Arabic Freedict dictionary
|
||
dict-freedict-eng-cro - Dict package for English-Croatian Freedict dictionary
|
||
dict-freedict-eng-cze - Dict package for English-Czech Freedict dictionary
|
||
dict-freedict-eng-deu - Dict package for English-German Freedict dictionary
|
||
dict-freedict-eng-fra - Dict package for English-French Freedict dictionary
|
||
|
||
Now after that you have successfully installed dictd and can look up definitions.
|
||
|
||
First, let’s check if dictd server is running and what databases are installed:
|
||
|
||
$ dict -I
|
||
|
||
Example of output:
|
||
|
||
dictd 1.12.0/rf on Linux 3.2.0-29-generic-pae
|
||
On my_host: up 95.000, 2 forks (75.8/hour)
|
||
|
||
Database Headwords Index Data Uncompressed
|
||
gcide 203645 3859 kB 12 MB 38 MB
|
||
moby-thesaurus 30263 528 kB 10 MB 28 MB
|
||
|
||
To look up a word definition you need to use a particular dictionary of those you have installed. Let’s check the English one (gcide):
|
||
|
||
$ dict -d gcide [word you want to look up]
|
||
|
||
If you don’t use the **-d** parameter dictd will search all available databases and return matched definitions.
