Debian (and probably ubuntu as well) has a package called "devscripts" which
contains a handy tool called "checkbashisms". This tool tells you if your script
uses bash-specific stuff and often even suggests a more portable alternative.
I haven't checked DVM yet, but if you want to have stuff done one login, put it
into ~/.profile instead of ~/.bashrc - this should be executed by all POSIX
compliant shells I think.
