linux - 从日志文件中提取最近 24 小时的数据

Question

我想显示最近 24 小时的日志

我试过了，但这不是最好的动态方式。

utmpdump /var/log/wtmp* | awk '/2022-09-22/, /2022-09-23/'

运行脚本时显示的任何其他方式应该持续 24 小时

Answer 1

不一定是 24 小时(但您的问题也只过滤昨天和今天，而不考虑当前时间)，但也许您正在寻找 command substitution替换昨天和今天的日期？

utmpdump /var/log/wtmp* | awk "/$(date -I -dyesterday)/,/$(date -I)/"
