solution

Use the HISTTIMEFORMAT variable to specify that the timestamp is added to the command

edit/etc/profilefile, add the following variables at the bottom

After the modification is complete, restart the server, or refresh the profile with the following command:

Re-execute history as shown below:



remark

HISTTIMEFORMAT uses the time format of the strftime function.

Manual for strftime functions:

%F     Equivalent to %Y-%m-%d (the ISO 8601 date format). (C99)
%T     The time in 24-hour notation (%H:%M:%S).  (SU)
(End)
