2.14 Spell check and dictionary operation

Most Linux distributions contain a dictionary file, along with a aspell tool that is useful for spell checking

1, the directory/usr/share/dict/contains some dictionary files, "dictionary file" is a dictionary word list contains a text file, you can use this list to check whether a word is a word in the dictionary.

To check whether a given word belongs to a word in the dictionary, use the following script:

#!/bin/bash

#文件名: checkword.sh

Word=$1

grep "^$1$"/usr/share/dict/british-english-q

If [$?-eq 0]; Then

Echo $word is a dictionary word;

Else

Echo $word is not a dictionary word;

Fi

The syntax for this script is as follows:

./checkword.sh ful

Ful is not a dictionary word

./checkword.sh Feel

Ful is a dictionary word

Working principle

In grep, ^ marks the beginning of a word, and $ marks the end of the word.

-Q Disables the generation of any output

We can also use the spell checker command Aspell to check a word in the dictionary

#!/bin/bash

#文件名: aspellcheck.sh

Word=$1

Output= ' echo \ ' $word \ ' | Aspell List '

If [-Z $output];then

Echo $word is a dictionary word;

Else

Echo $word is not a dictionary word;

Fi

When the given input is not a dictionary word, the Aspell List command produces the output text, and conversely does not produce any output,-Z is used to confirm whether the $output is empty.

Lists all the words in the file that start with a specific word:

$look Word filepath

Or

$grep "^word" filepath

By default, if the file parameter is not given, the look command uses the default dictionary (/usr/share/dict/words) and returns the output.

$look Word

#像这样使用时, the Look command takes the default dictionary as the file parameter
