I have recently been doing a fair bit of work on some DNS/DHCP appliances that are based on a version of RHEL, as a result I have started to use the Bash shell alot more. In the past on Solaris and HP-UX I have resorted to using KSH and had configured my .profile to pretty much work how I needed.
Although if I really wanted I am sure I could carry on using KSH and update the .profile to work with the RHEL boxes, however how boring. I decided to use Bash (various reason) I thought that I should probably get it to work exactly how I want, so here is my journy.
