Better shell history for power users.

One of the very first things I set up on any new OS install is my history. I like to keep a lot of it and I like to know when I ran the command. This is very easy to do with these two environment variables set in your profile. You can set them locally or globally.

[royce@royce-desktop ~]$ cat /etc/profile.d/history.sh 
export HISTSIZE=100000
export HISTTIMEFORMAT="[%F %T] "
[royce@royce-desktop ~]$ history |tail -n 2
