Greetings,
I noticed a subtle difference in symbolic links between Linux and
OpenSolaris.
Look at the two examples below. It is like OpenSolaris is treating the
sym link like a hardlink. So what is the problem? Under OS pwd returns
the link name as the current working directory if you cd into the
symlinked dir and under Linux pwd return the target name as the current
working directory if you cd into the symlinked dir.
A simple question should answer your questions: What shell did you use with
which test?

I used tcsh on Solaris Sparc and Linux and bash on OpenSolaris. Due to
many responses I now know that different shells will give different
results with pwd and symlinked directories.
Paul,
Just to beat the dead horse a bit further...
pwd is a built-in function of bash/sh/ksh. I don't believe that pwd is
built into csh. There is also the command /usr/bin/pwd which should
always return the "true" path.

pw...@nova:/tmp$ cd dir2
pw...@nova:/tmp/dir2$ pwd

pw...@nova:/tmp/dir2$ ps

Take a look at the man pages for bash(1) and pwd(1) for details.
