我有一个日志文件，其中包含：
... freeswitch.log:2011-09-08 12:21:07.282236 [ERR] ftdm_queue.c:136 Failed to enqueue obj 0x7f2cda3525c0 in queue 0x7f2ce8005990, no more room! windex == rindex == 58! freeswitch.log:2011-08-08 13:21:07.514261 [ERR] ftdm_queue.c:136 Failed to enqueue obj 0x7f2cda354460 in queue 0x7f2ce8005990, no more room! windex == rindex == 58! freeswitch.log:2011-06-04 16:21:08.998227 [ERR] ftdm_queue.c:136 Failed to enqueue obj 0x7f2cda356300 in queue 0x7f2ce8005990, no more room! windex == rindex == 58! freeswitch.log:2011-09-08 12:21:10.374238 [ERR] ftdm_queue.c:136 Failed to enqueue obj 0x7f2cda3581a0 in queue 0x7f2ce8005990, no more room! windex == rindex == 58! ...
如何使用linux命令行工具按每行的时间戳降序对文件排序？
使用sort的-k标志：
sort -k1 -r freeswitch.log
这将通过第一个键对文件进行反向排序（即freeswitch.log：2011-09-08 12：21：07.282236）。如果文件名始终相同（freeswitch.log），则应按日期排序。
