这是我拥有的mongoDB配置文件，我需要像这样更新文件中的密钥，

port: 27017 
bindIp: 0.0.0.0 
#security: 
keyFile:/opt/mongodb/keyfile 
authorization: enabled 
#replication: 
replSetName: mongoreplica1

如何使用bash脚本执行此操作？

Answer 1

您可以使用

来修复sed命令

sed -i 's/^\( *bindIp *: *\).*/\10.0.0.0/'

BRE POSIX模式^\( *bindIp *: *\).*匹配

^-字符串的开头
\( *bindIp *: *\)-捕获组＃1（在RHS中称为\1）：零个或多个空格，bindIp，零个或多个空格，:和零或更多空格
.*-该行的其余部分

使用sed修改配置文件
