How to Add Date & Time with History in Linux

Introduction

The command history allows the use of words from previous command lines at the command prompt type. This simplifies spelling corrections and the repetition of complicated commands or arguments.

History Command

# history
  850  useradd admin
  851  passwd admin
  852  cd /home/admin/
  853  ls -l
  854  ls -la
  855  top

Edit the file /etc/bashrc add the entry at the end of the file /etc/bashrc

# vi /etc/bashrc
export HISTTIMEFORMAT="%h/%d - %H:%M:%S "

OR
You can also directly execute the following command:

# export HISTTIMEFORMAT="%h/%d - %H:%M:%S "

Now again check the “history” command:

# history
  850  31/08/15 07:22:21 useradd admin
  851  31/08/15 07:22:21 passwd admin
  852  31/08/15 07:22:21 cd /home/admin/
  853  31/08/15 07:22:21 ls -l
  854  31/08/15 07:22:21 ls -la
  855  31/08/15 07:22:21 top
