使用 vi 编辑器在每个 X 行插入新文本
Insert new text at every X line using vi editor
我目前有一个 yaml 文件(这个文件很大,格式如下):
- created_at: 2021-01-18 15:11:44
created_by: joe
hostname: sfo
ip: 1.1.1.1
opersys: tmsh
platform: f5
role: lb
type: loadbalancer
- created_at: 2021-01-18 15:11:44
created_by: joe
hostname: sjc
ip: 2.2.2.2
opersys: tmsh
platform: f5
role: lb
type: loadbalancer
我想在每 8 行插入一个新文本 (serial_num: xxxxx),因此它看起来像这样:
- created_at: 2021-01-18 15:11:44
created_by: joe
hostname: sfo
ip: 1.1.1.1
opersys: tmsh
platform: f5
role: lb
type: loadbalancer
serial_num: xxxxx

created_by: joe
hostname: sjc
ip: 2.2.2.2
opersys: tmsh
platform: f5
role: lb
type: loadbalancer
serial_num: xxxxx
纯Vim,:help :global
和:help :put
:
" after every line matching 'type:'
:g/type:/put=' serial_num: xxxxx'
" before every line matching 'type:'
:g/type:/put!=' serial_num: xxxxx'
纯Vim,:help :global
和:help :normal
:
" after every line matching 'type:'
:g/type:/normal oserial_num: xxxxx
" before every line matching 'type:'
:g/type:/normal Oserial_num: xxxxx
使用 GNU Sed
sed '/type: /a\ serial_num: xxxxx' your_file
