如何實施softlink vimdiff

Question

我發現vimdiff實用程序只是vim的軟鏈接。兩者都位於我的Suse11盒中的/usr/bin/下。和vimdfiff是vim的軟鏈接。有趣的是，vimdiff file1 file2實際上是vim -d file1 file2等同，所以在這個意義上 的-d選項會自動嵌入在軟鏈接，所以我的問題是如何 簡單？

Answer 1

Vim的在其main()函數使用argv[0]來區分它的可執行文件的名稱，其執行該檢查vim或vimdiff，或等等

Link to vim main.c分化rvim，rview，gvim，gview，vimdiff，gvimdiff，ex，exim。

/* 
* Check for: [r][e][g][vi|vim|view][diff][ex[im]] 
* If the next character is "e" we run in Easy mode. 
* If the next character is "g" we run the GUI version. 
* If the next characters are "view" we start in readonly mode. 
* If the next characters are "diff" or "vimdiff" we start in diff mode. 
* If the next characters are "ex" we start in Ex mode. If it's followed 
* by "im" use improved Ex mode.
