extract words frm dictionary

could u pls tell me which would be the efficient way to extract all the words(which has all the specified letters ) from a linux dictionary..

example
get all the valid words with letters with letters A,B,C,D,E,H

what do you mean by linux dictionary?

It depends on what you mean by dictionary and valid words. For example: on my machine in /usr/share/dict/ directory there is a file named words. It starts with ``aback'', ends with ``zoos'' and contains 38619 words. To search through it the words containing a, b, c, d, e and h letters exclusively I use the command:

Code:

egrep -e "^[abcdeh]+$" words

In result it displays 47 words:

Code:

abbe

abed

accede

acceded

ace

ache

ached

ad

add

added

ah

ahead

babe

bad

bade

bah

be

beach

beached

beachhead

bead

beaded

bed

bedded

bee

beech

behead

cab

cache

cached

cede

ceded

dad

dead

decade

deed

deeded

each

ebb

ha

had

he

head

headache

headed

heed

heeded

On the other hand if you mean dictionary in any other format than plain ASCII text file extracting words from it could be tricky or simply impossible.

i mean the words present in usr/share/dict/words in linux

hey can u pls tell me how to do the same in a progaram written in java ?
can i use
egrep -e "^[abcdeh]+$" words

inside java program which runs on linux machine?
