bash complete 怎麼使用

Bash complete 的概念是，將某些 regression expression 與某個指令做連結，如此一來，就可以對該指令使用 tab tab 來 auto-completion。


先看一個 example：
假設我的家目錄底下有 A.cpp, B.cpp C.cpp 這些檔案


$ ls
A.cpp B.cpp C.cpp


建立一個新的可執行檔，叫做 example，我們之後要讓 example 可以跟 *.cpp 做 auto-completion

$ touch example
$ chmod +x example



建立連結：

$ complete -f -X '!*.cpp'example



馬上來實驗：

$ example [tab] [tab]
A.cpp B.cpp C.cpp
