Re: pwd-problem

[Richard Ramos <rramos at coreenetworks dot com>]

Let me take this opportunity to describe some pwd-related behavior that
I thought was unexpected.  Maybe we can hash out the whole "pwd" question.

My not-so-informed opinion is that the behavior you see is what I would
have expected since the command would have executed in you current
directory.

I put together a  script to illustrate the unexpected behavior I see:

$cat testscr
#! /bin/sh

echo \$PWD=$PWD
echo cd ..
cd ..; echo pwd produces: `pwd`
echo \$PWD = $PWD

The output of the script is as follows:

$ tstscr
$PWD=/home/rramos
cd ..
pwd produces: /home
$PWD = /home/rramos

The pwd command seems to produce the result I would have expected
(the directory changes according to the script) but the PWD variable stays
fixed at the directory where I ran the script from.  I thought the PWD
variable should have followed along.
