Hey All,
Following Hamei's excellent example, I'm rebuilding redbox and have decided to try and use as much as possible of the default software that IRIX 6.5.30 provides. So I'm currently using the default Ksh as my shell rather than trusty old GNU Bash.
Which is fine, except that life without <TAB> filename auto-completion is trying. Turns out that you can get most of that back in Ksh by hitting <ESC><ESC> rather than <TAB>. Well, after you've set your keyboard mode to EMACS as shown below.
I also like my prompt to tell me who I am and where I am, and my up/down arrows to recall my command line history. In Bash you get command line history on the arrow keys for free and you set your prompt with something like: PS1="\u@\h \w".
In IRIX Ksh (which is actually the venerable Ksh88) something similar can be achieved, but it's a bit more involved.
1. put the following into your $HOME/.profile
ENV="$HOME/.kshrc"
export ENV
2. create a $HOME/.kshrc and insert the following:
Like the Meerkat says; "Simples."
