How to know which programming language is set for highlighting the syntax in vim. I can set the language by "setf" command, but how to get the current language?
Thanks.

Vim is written in C language. According to Wikipedia, Vim is written in both C and Vimscript, not only Vimscript. The source code of Vim is available here, on Github. /src : 26.321M , mostly written in C. Most of the files are .
Syntax highlighting enables Vim to show parts of the text in another font or color. Those parts can be specific keywords or text matching a pattern. Vim doesn't parse the whole file (to keep it fast), so the highlighting has its limitations.
After opening login.sh file in vim editor, press ESC key and type ':syntax on' to enable syntax highlighting. The file will look like the following image if syntax highlighting is on. Press ESC key and type, “syntax off” to disable syntax highlighting.
You can type :set ft? (Note that the question mark is part of the command)
