I do not know the command line for symbolic links. I created the
symbolic link of /Centos/5 to /Centos/5.1 in Nautilus which does not
have a method of changing a symbolic link. Only deleting it and
creating a new one.


Is there a command line to change /Centos/5 to link to /Centos/5.2 ?

IMNSHO, anyone that has more than 2 Centos boxes should maintain their
own local repo. Of course it only took me a few years until I got mine
up and running! Just had some challenges walking the talk

Not that I know of, I always just delete an recreate it using "rm -f"
and "ln -s" at the command line.

I just delete and re-create it

I agree with this when maintaining more than a couple boxes, certainly
if maintaining more than 4 or 5 at the same location, especially with
limited bandwidth.

It used to be that the -f worked. Sometime in the past that disappeared.
Bad decision, IMHO.

It's still there:

nox:~/tmp/ln$ touch foo
nox:~/tmp/ln$ touch bar
nox:~/tmp/ln$ ln -s foo baz
nox:~/tmp/ln$ ll
total 12
-rw-r--r-- 1 gavin gavin 0 Jun 26 10:06 bar
lrwxrwxrwx 1 gavin gavin 3 Jun 26 10:06 baz -> foo
-rw-r--r-- 1 gavin gavin 0 Jun 26 10:06 foo
nox:~/tmp/ln$ ln -sf bar baz
nox:~/tmp/ln$ ll
total 12
-rw-r--r-- 1 gavin gavin 0 Jun 26 10:06 bar
lrwxrwxrwx 1 gavin gavin 3 Jun 26 10:06 baz -> bar
-rw-r--r-- 1 gavin gavin 0 Jun 26 10:06 foo


It does seem to be flaky though. I definitely have had times it hasn't
worked recently.

Cheers,
Gavin

If there's already a link to a directory, you need -n (usually);

-n, --no-dereference
treat destination that is a symlink to a directory as if
it were a normal file

Otherwise, you'll end up with a rogue link inside the existing directory:

mikaelf@mikaelf:/tmp/ln$ ln -sf foo link
mikaelf@mikaelf:/tmp/ln$ ls -lR
.:
total 8
drwxr-xr-x 2 mikaelf mikaelf 4096 2008-06-26 11:19 bar
drwxr-xr-x 2 mikaelf mikaelf 4096 2008-06-26 11:16 foo
lrwxrwxrwx 1 mikaelf mikaelf 3 2008-06-26 11:19 link -> bar

./bar:
total 0
lrwxrwxrwx 1 mikaelf mikaelf 3 2008-06-26 11:19 foo -> foo

./foo:
total 0
