Here is a list of things I did to make AIX feel more at home:

• Install everything on the AIX Toolbox for Linux applications, and setup bash as the shell (the default shell feels like running sh on a broken terminal) The newest packages can be found at ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox. Compiling stuff from scratch is not that straightforward on AIX, so it is nice to have it done for you.
• Compile and install less, wget etc.
• PAGER=less in /etc/environment to get rid of the shitty pager that comes with AIX
• Set bash as default shell
• alias make=gmake (replacing the AIX make is not a good idea)

There are also some things that are nice on AIX. One of them is smitty.
