I suggest you add into
the remark that was on
$ help pwd
pwd: pwd [-LP]
Print the current working directory. With the -P option, pwd prints
the physical directory, without any symbolic links; the -L option
makes pwd follow symbolic links.
It would save other people bothering you on that subject :-)
