cd ~homedir not working

Allanm — Mon, 02 Nov 2009 23:41:12 GMT

For sometime now, I am unable to do -

cd ~homedir
but
cd /homedir works...

Can you suggest some pointers as to how I can troubleshoot or fix this?

Thanks,
Allan.

Also sudo bash takes a very long time to come back to the password prompt...

If you want "/homedir", then say "/homedir".
The "~user_name" notation is used with a user
name. That path to that user's home
directory is obtained from the "passwd" data
base ("/etc/passwd", or wherever). Unless
there's a user name of "homedir", "~homedir"
makes no sense.

What is the user name here?

Where is that user's home directory?

Sorry I meant cd ~user-home-dir, cd /user-home-dir works.

Also sudo bash is very slow to respond...

So, does that mean that you're happy, or is
there still a problem/question there?

> Also sudo bash is very slow to respond...

A different thread with "sudo" in the Subject
might get more attention from people who know
more about sudo than I.

Hi.

Did you check which is the homedir set for your user?

getent passwd

Next to last field is homedir.

When you execute "cd ~foo", the shell checks the home directory location of user "foo" from the user database (usually /etc/passwd, but can be NIS or LDAP too if configured) and then moves to that directory.

If the user "foo" has his home directory set as /home/bar, the command "cd ~foo" moves to /home/bar.

Since you say your "cd /homedir" works, it is probably not a home directory permission problem.

Maybe the user cannot look up the home directory location for some reason?
What are the permissions of /, /etc and /etc/passwd?

Please run:

ls -ld / /etc /etc/passwd

The response should be something like this. Note the permissions:
drwxr-xr-x 25 root root 4096 2009-10-20 13:30 /
drwxr-xr-x 162 root root 16384 2009-11-03 12:57 /etc
-rw-r--r-- 1 root root 1854 2009-10-06 15:18 /etc/passwd

normally 'cd ~' will take you to your own home dir. 'cd ~userhomedir' will not work because that would translate to something like /home/user/user, which probably doesn't exist.

if you want to do 'cd ~otheruserhomedir', i'm not aware this is possible. afaik ~ always points to your own home dir and thus you should address others home dirs always as a full path.

For a valid explanation of what this means,
see Matti Kurkela's response.

> [...] i'm not aware [...]

Try it?

debi# cd ~
debi# pwd
/root
debi# cd ~ftp
debi# pwd
/home/ftp

debi# grep '^ftp:' /etc/passwd
ftp:x:110:65534::/home/ftp:/bin/false

Or read about it. "man " should
provide the details.
