cd $DIR_NAME problem

cd $DIR_NAME problem

[Joe Walker]

I found a very wierd problem by trying to run a GNU configure script.
A boiled down version is below:

% pwd
	/home/jurua/walkerjj/l

% ls -l

	total 2
	drwxr-xr-x  2 walkerjj      512 May 11 15:43 test_dir
	-rwxr-xr-x  1 walkerjj       84 May 11 15:43 test_script

% cat test_script

	#!/bin/sh -x

	DIR="test_dir"
 	echo "DIR is ($DIR)"
	cd $DIR
	echo "Test passed"

% test_script

	DIR=test_dir
	+ echo DIR is (test_dir)
	DIR is (test_dir)
	+ cd test_dir
	test_script: test_dir: bad directory


So that is the problem: any shell script that changes to a directory using a
variable, fails.

However it get stranger:

% mv test_* ..
% cd ..
% pwd
	/home/jurua/walkerjj

% test_script

	DIR=test_dir
	+ echo DIR is (test_dir)
	DIR is (test_dir)
	+ cd test_dir
	+ echo Test passed
	Test passed


For all of the above:

% echo $ZSH_VERSION

	2.6-beta8

% uname -a

	SunOS jurua 4.1.3_U1 8 sun4m


I've only edited the output to make it easier to read.
Sorry but I don't know enough about Z-shell internals yet to be able to suggest
a fix.

Thanks,

Joe.

Thanks. the explanation is correct.
I'm not sure that this isn't a bug though- the situation seams to be:

If the 'cd' command uses a variable then require . to be in CDPATH
otherwise don't.

So Zsh seams to be in disagreement with itself.
Is this correct?

Joe.
