需求:
排查线上问题,回溯历史数据,需要知道历史数据执行到什么时间(日志有时间戳数据), 但是时间戳不易读。因此使用 xargs 做转换
实现:
for i in `seq -w 50 69`; do echo " log time ,1560${i}2917,xxx"; done |awk -F ',' '{print "@"$2}' |xargs -I{} date --date {} ; date +"%F"
输入:
log time ,1560502917,xxx
log time ,1560512917,xxx
log time ,1560522917,xxx
log time ,1560532917,xxx
log time ,1560542917,xxx
log time ,1560552917,xxx
log time ,1560562917,xxx
log time ,1560572917,xxx
log time ,1560582917,xxx
log time ,1560592917,xxx
