Adding Date And Time To Your Bash History
http://www.howtoforge.com/adding-date-and-time-to-your-bash-history
This is a quick but handy addon (RedHat/CentOS) to enhance your bash history (bash > 3.0).It comes in handy particularly if there are multiple people maintaining a given server (so you can see when a command was performed) or even if you are the sole maintainer, but can't remember exactly when you did or changed something. Edit your /etc/bashrc and append to the bottom:
export HISTTIMEFORMAT="%h/%d - %H:%M:%S" From next login instead of: 574 tail -f /var/log/maillog
575 mailq | tail -15
576 tail -f /var/log/maillog
577 less /var/log/maillog you get: 1002 Apr/30 - 11:46:16 grep duncan /var/log/maillog
1003 Apr/30 - 14:17:40 passwd jduncan
1004 Apr/30 - 14:18:02 smbpasswd jduncan
1005 Apr/30 - 14:50:28 history 10 Hope this helps someone;)
