 Set Date and Time for Each Command You Execute in Bash History

 ============================================================
 
 By default, all commands executed by Bash on the command line are stored in history buffer or recorded in a file called ~/.bash_history. This means that a system administrator can view a list of commands executed by users on the system or a user can view his/her command history using the [history command][1] like so.
