Enable history timestamp for bash history command

Here is a way of how you can see a timestamp for executed command when using "history" command in Linux.



You can export HISTTIMEFORMAT variable, with appropriate date formatting.

For example you can use:

export HISTTIMEFORMAT='%F %H:%M:%S '

In this case the history command will give you an output like this:

~> history
