Where Am I?

The Unix terminal is a very customizable environment. One easy customization is to change your static, uninformative default bash command prompt "[jharvard@researchgrid]$" to update and show you where you are when you change directories. Please see the HOW-TO on our HBS Research Computing Environment website at http://grid.rcs.hbs.org/change-your-unix-command-prompt-now.
