Can't do: sudo cd /var/cron/tabs

[Ladner, Eric (Eric.Ladner)]

This problem comes up a lot with shell expansion of wild cards through
non-readable directories and shell builtin commands.

A more functional exchange would be (you're original output with some
editing and made up content):

valhalla: /var/cron $ ll
total 1
dr-xr-xr-x   3 root  wheel   512 Jul 16 17:26 ./
drwxr-xr-x  24 root  wheel   512 Oct  1  2001 ../
-rw-------   1 root  wheel   434 Jul 16 17:40 log
-rw-------   1 root  wheel  1079 Jul 16 17:00 log.0.gz
-rw-------   1 root  wheel  1172 Jul 16 03:00 log.1.gz
-rw-------   1 root  wheel  1158 Jul 15 13:00 log.2.gz
-rw-------   1 root  wheel  1073 Jul 14 23:00 log.3.gz
drwx------   2 root  wheel   512 Mar 10 16:59 tabs/
valhalla: /var/cron $ cd tabs
ksh: cd: /var/cron/tabs - Permission denied
valhalla: /var/cron $ sudo ls tabs
-rw-------   1 root  wheel   434 Jul 16 17:40 stuff
-rw-------   1 root  wheel  1079 Jul 16 17:00 junk
-rw-------   1 root  wheel  1172 Jul 16 03:00 root
valhalla: /var/cron $ sudo vi tabs/root


Note also that the way sudo and the shell expand wildcards, this doesn't
work since the shell can't expand the wildcard appropriatly.

valhalla: /var/cron $ sudo vi */root 
valhalla: /var/cron $ sudo vi tabs/ro*  # This won't work either.

Below you'll see that I'm trying to cd to the /var/cron/tabs directory.
For some reason I cannot do it.  I assumed this was because I was not
root.  Therefore, I try to use sudo.  However, sudo doesn't work with
cd.  Can someone help me understand the following:

 1.  Why can't I cd to the tabs directory?
 2.  Why will sudo not work with cd?

Your help is appreciated.
