sed命令实现文件内容替换总结案例

sed -i "s@AAAAA@BBBBB@g" /home/local/payment-biz-service/env/test.txt

 

sed -i "s#htxk.*#htxkAAAAA#g" /home/local/payment-biz-service/env/test.txt

案例使用：

项目中经常需要更改数据库链接地址，由于是多个项目同时更换

所以使用sed批量更改

将/home/local/payment-biz-service/env/目录下的db.propertiesbak文件中连接信息

 

 

jdbc.url=jdbc:mysql://192.168.10.101:3306/snsdb_test?allowMultiQueries=true

 

改成

jdbc.url=jdbc:mysql://192.168.10.71:3306/sportdb_test?allowMultiQueries=true

命令如下：

sed -i "s@mysql://192.168.10.101:3306/snsdb_test?allowMultiQueries=true@mysql://192.168.10.71:3306/sportdb_test?allowMultiQueries=true@g" /home/local/payment-biz-service/env/db.propertiesbak 

 

案例2：如果需要批量替换多个目录的db.properties文件内容呢？

分2步实现：

1.获取所有需要修改的db.properties文件列表

find / -type f -path '/home/local/*-service/env/db.*' -type f ! -path "*bak*" -type f ! -path "*db.properties_*"

 

2.执行批量修改命令

find / -type f -path '/home/local/*-service/env/db.*' -type f ! -path "*bak*" -type f ! -path "*db.properties_*" | xargs sed -i "s@mysql://192.168.10.101:3306/snsdb_test?allowMultiQueries=true@mysql://192.168.10.71:3306/snsdb_test?allowMultiQueries=true@g"
