Linux Vi/vim Edit file displays line number

Method One ( the most embarrassing method ):

1, display the current line number, in the VI command mode input

: Nu

2, display all line numbers, in the VI command mode input

: Set nu          #这是: Shorthand for set number

Method Two ( the best method ):

Using VI to edit the ~/.VIMRC file, the file does not exist automatically generate a new file, so do not worry about the existence of the file, add a line "set Nu" in the file, adding the content without quotation marks, the command is as follows:

[Email protected] ~]# VI ~/.VIMRC

#生成 the. vimrc file, enter the following in the first line:

Set number #vi, VIM is applicable! A once in a way

Method Three ( only vim effective, VI invalid!) If you want VI to take effect, use method two ):

The configuration file for VI in Ubuntu is stored in the/etc/vim directory with the configuration file named VIMRC

The configuration files for the VI in Fedora, Red Hat Linux (CentOS) are stored in the/etc directory, and the configuration file is named VIMRC

Use VI to edit the file, adding a line of "set Nu" to the file, with the added content without quotation marks. ：

[Email protected] ~]# VIM/ETC/VIMRC #Fedora, Red Hat Linux (CentOS) commands

[Email protected] ~]# VIM/ETC/VIM/VIMRC #Ubentu的命令
