Man*_*nde 9 bash command-history timestamps
当history执行命令时,它显示最近执行的命令的列表。是否有任何规定可以让我们看到执行这些特定命令的时间?

您需要设置HISTTIMEFORMATenv 变量。
来自help history:
Run Code Online (Sandbox Code Playgroud)If the $HISTTIMEFORMAT variable is set and not null, its value is used as a format string for strftime(3) to print the time stamp associated with each displayed history entry. No time stamps are printed otherwise.
strftime 联机帮助页中描述了该格式。
$ export HISTTIMEFORMAT='%F %T '
$ history|tail -2
501 2014-11-03 20:51:41 export HISTTIMEFORMAT='%F %T '
502 2014-11-03 20:51:44 history
