Question

我要求将我的仪表组合文件中的[我的舱面]部分移至我的板块组合文件上的另一节,标题是<编号>#SAFE#;在移到该节之后,各科之间应当有空间。

使用的代码:

#!/bin/bash
for server in `cat /home/servers.txt `
username=$1
password=$2
do
sshpass-p $PWD ssh -o stricthostchecking=no $USERNAME@$server "ed -s /home/my.cnf << EOF 
/^[已婚]$/;/^[.*/ -1m$
?[已婚]?i

.
w
EOF"
done

a. 实际:

[已婚]

disable-log-bin = 1

skip-name-resolve = 1
performance-schema = 0
local-infile = 0
mysqlx = 0
open_files_limit = 200000
max_allowed_packet = 256M
sql_mode="NO_ENGINE_SUBSTITUTION"

#the below are password related of [已婚]
 validate password=1

innodb_dedicated_server = 1
innodb_buffer_pool_instances = 48

[myisamck]
a=3
b=4

[sst]
d=3
c=4

# SAFE #
d=0
f=0

要求:[已婚] section and its section should be pasted above # RSE # ( section in very small cases section is given as #SAFE## or #SAFE# or # RSE # in small of my.cnf file),Please support.

预期产出:

[myisamck]
a=3
b=4

[sst]
d=3
c=4

[已婚]

disable-log-bin = 1

skip-name-resolve = 1
performance-schema = 0
local-infile = 0
mysqlx = 0
open_files_limit = 200000
max_allowed_packet = 256M
sql_mode="NO_ENGINE_SUBSTITUTION"

#the below are password related of [已婚]
 validate password=1

innodb_dedicated_server = 1
innodb_buffer_pool_instances = 48

# SAFE #
d=0
f=0

Answer 1

我不使用<代码>sshpass,但便携式编码<>ssh,其中关键内容如下:

#!/usr/bin/env bash

servers=(
  server1
  server2
  server3
  ...
)

for server in "${servers[@]}"; do
  ssh -t "jetchise@$server"  ed -s ~/my.cnf <<EOF
  /#[[:space:]]*SAFE[[:space:]]*#/kx
  /^[mysqld]$/;/^[.*/-1m   x-1
  ,p
  Q
EOF 
done

为将<代码>/home/servers.txt的内容添加到一个阵列中,一种办法是使用mapfile aka readarray。它是双面4+特征。

mapfile -t servers < /home/servers.txt

在<代码>、p的行文后面加上w。
删除<代码>,p以保持产出不变。
