问题描述
我注意到bash shell可以为您的命令建议命令行开关。
只需键入命令,破折号( - )和类型选项卡即可。
<$ c $ c> andy @ andyx:〜$ java -
b
$ b
问题是:
如何与此功能介面。也就是说,如果我写了一个程序,要从控制台运行,什么是API告诉shell什么开关可用?
解决方案
您发现了Bash的功能。
I noticed that the bash shell can suggest command line switches for your command.
Just type your command, a dash (-) and type tab. The shell will show you available switches.
For example, try:
andy@andyx:~$ java -
and press tab - Surprise!
The question is:
How do I interface with this feature. I.e., if I write a program that is to be run from the console, what's the API to tell the shell what switches are available?
解决方案
You have discovered Bash's programmable completion feature.
