Display the Timestamp in Redhat

Issue

• How to display the timestamp for history command?
• Unable to see timestamp for history command

Resolution

• Typically when you type history from a command line, it displays the command # and the command. For auditing purpose, it may be beneficial to display the time stamp along with the command as shown below:

  # export HISTTIMEFORMAT='%F %T '
  

• Or, to make the change permanent for the current us

$ echo 'export HISTTIMEFORMAT="%F %T "' >> ~/.bashrc
$ source ~/.bashrc

• Then run the history command:

Raw
