命令获取时间(以毫秒为单位)
问题描述：
Linux中是否有shell命令来获取以毫秒为单位的时间?
Is there a shell command in Linux to get the time in milliseconds?
答
date +%s%N返回秒数+当前纳秒.
date +%s%N returns the number of seconds + current nanoseconds.
因此，echo $(($(date +%s%N)/1000000))是您所需要的.
示例:
$ echo $(($(date +%s%N)/1000000))
1535546718115
date +%s返回自纪元以来的秒数，如果有用的话.
date +%s returns the number of seconds since the epoch, if that's useful.
