As Linux users and engineers, we often have to look back in our bash history to figure out exactly where things went wrong. The worst is when you execute the `history` command and all you get is a list of the commands you ran without the date/time of the command execution included.
Thankfully, there's an easy solution. Simply run the following command which defines the `HISTTIMEFORMAT` environment variable and exports that environment variable whenever you login/establish a new shell.
echo 'export HISTTIMEFORMAT="%d/%m/%y %T "' >> ~/.bash_profile
%d – Day
%m – Month
%y – Year
%T – Time
After executing the command, run `source ~/.bash_profile` or close your bash shell and open a new one.
