在VIM命令行模式下，当前行的特殊字符/符号是什么？

Question

In VIM in command line mode a "%" denotes the current file, "cword" denotes the current word under the cursor. I want to create a shortcut where I need the current line number. What is the symbol which denotes this?

Answer 1

. (dot) stands for the current line.

To clarify: This is meant for stuff like :1,.s/foo/bar/g which will transform every foo to bar from the beginning of the file up to the current line.

I don't know know of a way to get the current line number expanded for a shell command, which is what you are trying to do by doing :!echo .

You can find out about the expansions that are done (like % and # for example) in :he cmdline-special .

Answer 2

如果要将当前行号传递给shell命令，可以执行

:exe "!echo " . line(".")

Answer 3

要返回屏幕底部当前行的行号，请使用：

:.=       

Answer 4

Commands in vim works on the current line so:

:s/foo/bar/g

will transform every foo in bar on the line you are currently on.
