技巧

shell多行注释

命令行模式下，注释掉line1与line2之间的行

line1,line2s/^/#/g

自动补全

Ctrl+n Ctrl+p
Ctrl+x Ctrl+?{....}

左右分割打开help文档

默认是上下分割来打开文档，但是对于宽屏，左右分割反而更加方便

:vert help xxx

逐个替换

全文直接替换:

:%s/old_str/new_str/g

加上参数c可以逐个替换，这样可以对每一个再确认:

:%s/old_str/new_str/gc

关于 search/replace 中的换行符

Search:

\n is newline, \r is CR(carriage return = Ctrl-M = ^M)

Replace:

\r is newline, \n is a null byte(0x00)

比如字符串 test1,test2,test3 把逗号换成换行：

%s/,/\r/g
