Linux ispell command

Linux 命令大全Linux Command Encyclopedia

The Linux ispell command is used for a spell checking program.

ispell will use the /usr/lib/ispell/english.hash dictionary file by default to check text files. If words not found in the dictionary are found in the checked file, ispell will suggest words to use, or let you add the new words to your personal dictionary.

Examples

Check the spelling of a file. For example, to check the testfile file, use the following command:

ispell testfile

If suspicious words appear in the file, the first suspicious word that appears is highlighted, and word correction suggestions along with ispell operation commands are shown at the bottom of the screen. As shown below:

netwrks File: testfile  
Linux netwrks are becoming more and more common, but security is often an overlooked  
issue. Unfortunately  
0: networks  
[SP] <number> R)epl A)ccept I)nsert L)ookup U)ncap Q)uit e(X)it or ? for help

In this example, "netwrks" is detected as an error, and correction information is displayed. At this point, type "0" to use "networks" to correct the error, while it continues to display the next error until all errors have been displayed.

From the above example, we can see that the file testfile contains spelling errors. After correcting the file, a backup file is needed. At this point, use the following command:

ispell-b testfile    #检查拼写错误的同时，备份文件

If the file has no spelling errors, no information is displayed. Using the ls command, we can also see that the backup file testfile.bak of testfile has been created in the current directory. The result is as follows:

$ ls #以列表的形式查看当前目录下的文件  
examples.desktop testfile_1 testfile.bak xx01 模板图片 音乐  
testfile testfile1 testfile_2 xx00 公共的视频文档桌面

Among them, the testfile.bak file is the backup file generated by the previous command, and its content is the same as the original testfile file.
