History with dates and time

Normally, we type the command for getting the command history in the terminal.


You have to add the following line into the file  ~/.bashrc  to view the history with dates permanently.

export HISTTIMEFORMAT=”%d/ %m/ %y %T “
and then, from terminal run,

#source ~/.bashrc
