Ignoring the obvious errors, there are two problem with this:
1) It causes 2 other programs to be started up *every* time sh(1) is
run. Consider the effect of this on a `make build' on a VAX. The
performance loss can be measured in hours, maybe even days.
2) There is absolutely no reason to do something that complicated.
Just save the host name in a variable and concatenate the default
PS1 (in the same way as my code does) in `.shrc'.
Why make the problem harder than it actually is??
