Under AmigaOS, there's a command called 'path' which will do about what you
say, expanding your path by the given directory(s). Here's the tcsh-alias i'm
using to emulate this behaviour:

alias path              'set path=( `sh -c "cd \!* ; pwd"` $path ) ; rehash'

Of course this doesn't deal with any of the permission-thingies you mention,
but i think such a command makes sense. (Would be even better if all the shells
would provide it :-/)


Just my $0.02 worth,
