User profile: ~/.VIMRC default does not exist can be created manually

# Vim ~/.VIMRC

1 "This file says quotation marks are comments

2 set Nu "Display line number

3 Set Hlsearch "highlight

5 syntax on "Syntax detection color display

Practice:

1. Copy the/etc/grub2.cfg configuration file to the/tmp directory and use the Find replacement command to delete the white space character at the beginning of the/tmp/grub2.cfg file; CentOS:/etc/grub.conf

%s/^[[:space:]]//g

2. Copy the/etc/rc.d/init.d/functions file to the/tmp directory, and add a # to the beginning of the line beginning with a blank character for each line of/tmp/functions with the find replacement command; The original whitespace character is reserved;

%s/^\s\+/#&/g

3, replace the/etc/sysconfig/init in/tmp/functions file is/var/log;

%[email protected]/etc/sysconfig/[email Protected]/var/[email protected]

4.Delete the line at the beginning of the/tmp/functions file so # starts with # and at least followed by a blank character #

%s/^\ (#\) \ (\s\+\)/\2/g

If there is any mistake, please correct me!

Thank you!
