In vim, when the tab key is set today, we accidentally realized that the tab key in vim is left with eight spaces, which is a waste of space. Baidu found that all the personalized settings of vim are controlled by a file named. vimrc, that is, by configuring the file. vimrc, we can tell vim how to personalize services for us. The first question is, where is the. vimrc file? Locate finds that this file does not exist locally. Baidu finds that this file should generally be placed in the user's root directory. So: echo $ HOME. because I used root to log on, $ HOME =/root. Therefore, you touch the file. vimrc under/root, and the next task is to configure. vimrc. The second question is how to configure it? In general, the tab key is equivalent to four spaces. We only need to add the following two lines to. vimrc: set ts = 4 set expandtab and restart vim. the experiment shows that the tab has four spaces. The configuration file vimrc is used for the first time to optimize some vim settings and find the path. other similar requirements can be found along this path.
