MySQL
- Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE)
- 数据库字符集问题
- 连接数据库后，显示数据库字符集：show variables like ‘%char%’;
linux
source:not found (ls -l `which sh` 输出lrwxrwxrwx 1 root root 4 Apr 21 13:57 /bin/sh -> dash)
- 需要重新软连接：参考
- rm -f /bin/sh
- ln -s /bin/bash /bin/sh
tail 输出中文乱码???
shell脚本传递参数中，若包含空格，会被分割
shell中启动多个jar包，并控制顺序。
- 示例场景：SpringCloud服务启动
- 按照正常的shell脚本启动：sh xx.sh
