Typically when you type history from command line, it displays the command# and the command. For auditing purpose, it may be beneficial to display the timestamp along with the command as shown below.
# export HISTTIMEFORMAT=’%F %T ‘
# history | more
1 2008-08-05 19:02:39 service network restart
2 2008-08-05 19:02:39 exit
3 2008-08-05 19:02:39 id
4 2008-08-05 19:02:39 cat /etc/redhat-release
Note: You can also setup the following alias to view the recent history commands.
alias h1='history 10' alias h2='history 20' alias h3='history 30'
