sdcv é uma versão para console do dicionário StarDict. A grande vantagem desta ferramenta é que você não precisa estar conectado à Internet para fazer uma consulta. Não está disponível (ainda) um dicionário inglês/português, então a dica de hoje aplica-se apenas para quem possui um razoável conhecimento da língua inglesa.

Instalação

Em sistemas Debian GNU/Linux e derivados, digite:

  $ sudo apt-get install sdcv

Em seguida, baixe os dicionários desejados. Os dicionários podem ser baixados dos seguintes sites:

1. Abloz.com
2. Abloz.com misc
3. Free On-Line Dictionary of Computing

A lista de dicionários disponíveis é muito grande. Eu instalei os seguintes dicionários:

• Moby Thesaurus II
• Oxford Advanced Learner's Dictionary
• English irregular forms

Para instalar os dicionários, siga os seguintes passos:

1. crie o diretório para os arquivos dos dicionários:

     sudo mkdir -p /usr/share/stardict/dic/
   

2. abra os arquivos bz2 baixados na localização criada no passo anterior:

     sudo tar xvjf stardict-dictd-moby-thesaurus-2.4.2.tar.bz2 -C /usr/share/stardict/dic/
   

   Faça o mesmo para cada um dos dicionários baixados.
   Para consultar, basta digitar o nome do comando, sdcv, seguido do termo que se deseja consultar:

     sdcv ibm
     trademark   International Business Machines the
     world's largest computer company, based in the
     US, which produces both  hardware and  software,
     especially for business users. IBM is sometimes
     informally called "Big Blue".//

     IBM /I-B-M/ Once upon a time, the computer
     company most hackers loved to hate; today, the
     one they are most puzzled to find themselves
     liking.
     
     From hackerdom's beginnings in the mid-1960s to
     the early 1990s, IBM was regarded with active
     loathing. Common expansions of the corporate
     name included: Inferior But Marketable;
     It's Better Manually; Insidious Black Magic;
     It's Been Malfunctioning; Incontinent Bowel
     Movement; and a near-{infinite} number of even
     less complimentary expansions (see also {fear
     and loathing}). What galled hackers about most
     IBM machines above the PC level wasn't so much
     that they were underpowered and overpriced
     (though that counted against them), but that
     the designs were incredibly archaic, {crufty},
     and {elephantine} ... and you couldn't _fix_
     them -- source code was locked up tight, and
     programming tools were expensive, hard to find,
     and bletcherous to use once you had found them.
     
     We didn't know how good we had it back then. In
     the 1990s, Microsoft became more noxious and
     omnipresent than IBM had ever been. Then, in the
     1980s IBM had its own troubles with Microsoft
     and lost its strategic way, receding from the
     hacker community's view.
     
     In the late 1990s IBM re-invented itself as a
     services company, began to release open-source
     software through its AlphaWorks group, and began
     shipping {Linux} systems and building ties to
     the Linux community. To the astonishment of all
     parties, IBM emerged as a staunch friend of the
     hacker community and {open source} development.
     
     This lexicon includes a number of entries
     attributed to `IBM'; these derive from some
     rampantly unofficial jargon lists circulated
     within IBM's formerly beleaguered hacker
     underground.
