change directory to dvd fails

MohitAnchlia — Thu, 28 Feb 2008 00:01:50 GMT

Version HP UX 11

I am little bewildered with what I am seeing. I create a directory dvd. When I run "ls" I see this directory:

drwxr-x--- 2 name group 96 Feb 27 15:52 dvd

I am the owner so I expect to atlease be able to change the directory. When I try to run "cd ./dvd" I get "sh: dvd: not found.".

Then I run rm -rf ./dvd. It runs successfully but when I run "ls". I still see dvd directory.

I also tried cd dv*, cd d* etc.

Is dvd reserved keyword or something ? Why am I not able to cd to this directory

Shalom,

dvd is not a reserved word.

If you have file system mounted on the directory dvd that would explain the behavior.

bdf, cd out of there maybe umount it

you are logged in as root or your self? what is your current working directory.

I tried both, I even tried login as root and also as a owner, but neither works. It just looks like something to do with the name. Could somebody try the same thing as I did and see if it works.

I had no problems with it. There may be bugs such that that the Other permissions messes up the Owner ones? Do you have ACLs? What does id(1) show?

Can you rename the directory and then try the cd? (I assume it will still fail.)

When I try to rename I get:

$ mv dvd dv1
mv: dvd: cannot access: No such file or directory

This directory has sufficient permissions

When I do find . -name "dvd" It returns with no results.

Here is one interesting thing. I tried cd *vd* and I could get in the directory. Then using same expression I was able to rm *vd*.

Also, what's more interesting is I again created dvd and this time I was able to cd to it.

I don't really understand what happened at that time

I would have to guess that you had an unprintable character in the name.

Hello,

Pete is right. You should have used "-b"
flag to check directory name for
unprintable characters:

ls -alsb

That is flag I always teach in Unix classes
as students get bitten by this problem once in
a while.

Older versions of Ignite would occasionally
report errors when finding file and
directory names with unprintable characters.

Cheers,
