# 1、也可以直接使用[less logfile],然后再键入"/keyword"来按照关键字查询日志
# 当通过keyword找到日志后,就可以使用向上或向下箭头来查看前后的日志,退出日志查看时直接按下Q键(大小写均可)即可
# 其相比[vi]命令的优点是:日志载入查询快,它是读一行解析一行的,而不是一次都载入内存
# 2、另附less到日志里面后的几个用法
# [gg]为定位到日志第一行,[G]为定位到日志最后一行,[/keyword]为向下搜索,[?keyword]为向上搜索
# [n]为向前搜索,[N]为向后搜索(注意这里的措辞:就是说当使用[?]时,[n]就是向上搜索,使用[/]时,[n]就是向下搜索)
# 3、还有一个[tail]也是比较常用的,用法为[tail -1000f logfile],作用是实时地显示日志的后1000行,达到实时监视的效果
# 参数[-f]会不停地读取最新的内容,使用[Ctrl+c]可以终止日志显示
