modifying link

[HPOPSW]

Currently there is a link on the server which goes to /sap/AT. How can we change this to go to /sap/BT?

Hi:

Remove (rm) the link and recreate it where you want it to point.

Hi James,

Thanks for the response. Since I am new to this, can you please let me know from where to remove the link and how to change it to other destination?

[Mel Burslan · Accepted solution]

cd /where/the/link/is
rm sym_link
ln /sap/BT sym_link

where you need to replace the word sym_link with the actual name of the link you have

Hope this helps

Hi:

Consider this:

# touch /tmp/myfile # create a file for play
# ln -s /tmp/myfile /tmp/mylink # point to it
# ls -l /tmp/mylink
# rm /tmp/mylink
# ln -s /tmp/myfile /tmp/yourlink # point with a different link
# ls -l /tmp/yourlink

Regards!

Hi (again):

Be sure the read the manpages for 'ln'. I have assumed in my examples that you had and want to create symbolic (soft) links. Hence the use of the '-s' switch.

Thanks James and Mel,

Please consider the below scenario and advice -

there is a link created for /oracle/KPC:
lrwxr-xr-x 1 orakhr dba 3 Dec 17 15:00 KPC -> KHR

This link currenlty goes to /oracle/KHR
How can I change it to go to /oracle/KTC ?Also how can I change the owner of the link that to oraktc.

[Avinash20]

# cd /oracle
# rm KPC
# ln -s KTC KHR

[Avinash20]

Also how can I change the owner of the link that to oraktc.

# chown orakhr /oracle/KTC

[Avinash20]

This is a way of saying thanks to the right answers

[Avinash20]

Oops.. Sorry .. Didnt read it carefully

This link currenlty goes to /oracle/KHR
How can I change it to go to /oracle/KTC

So presently

there is a link created for /oracle/KPC:
lrwxr-xr-x 1 orakhr dba 3 Dec 17 15:00 KPC -> KHR

You like file /oracle/KPC to link to /oracle/KTC

# cd /oracle
# rm KPC
# ln -s KTC KPC

With regards to ownership

# chown

[Avinash20]

With regards to ownership

# chown orakhr /oracle/KTC

Please no point for this

[HPOPSW]

Thanks Avinash, James and Mel for your responses.

Hi:

> Also how can I change the owner of the link that to oraktc.

Use 'chown -h' [see the manpages for chown()].

Having said that, you should remember that the permissions and/or ownership of a (symbolic) link do not matter. It's the permissions and the ownership of the file or directory to which the symbolic link points that determine access.

[Avinash20]

Note.. the link file will depend on the ownership of /oracle/KTC though !!

[James R. Ferguson]

Hi (again):

Using a simple 'chown' (without the -h) on a symbolic link changes the ownership of the thing that the link points to, NOT the ownership of the link itself!
