Shell: To delete listener log file contains text and xml format (自动清理监听日志)

整理的一个清理Oracle数据库监听日志的脚本，可以部署到监听进程的owner用户的crontab中(RAC通常是grid, 单实例通常是oracle),  实现的是监听日志大于1GB时，归档监听日志文本格式的文件如listener.log ，自动压缩保存， 后期循环自动覆盖， 11G 引入的ADR,  XML格式的文件19c前也无法自动清理，这个shell 目前是自动rm 7前天的， 关于19c 的日志自动清理后期会分享

清理数据库监听日志的脚本

• 清理多个监听日志
• 清理文本和XML格式，自动判断
• 根据文本格式大小默认1GB
• 根据XML格式生成日期默认7天前
• 支持ORACLE用户同时安装DB 和GRID，listener in GRID HOME
• 机器名带域名

Tip: 在hpux 11.31 环境中shell 中的if -eq 比对数值大小时，如果数值大小超过Integer 类型的上限时使用的是String的ASCII码值比对，容易出现错误判断。
