How to relink a file

ForumKid · 11-07-2002, 02:40 PM

Hi,
Currently this is my situation.
I have a file in /Apache/bin called jdk. It points/links to /usr/local/jdk. I need to update my jdk so now in /usr/local/ will be jdk1. So i want to create a link in /Apache/bin called jdk1 and have it link to /usr/local/jdk1..

Does this make sense. I think its quite easy. I have been messing around with ln but not sure that is the correct way to do it.
Thanks as always.

just use "ln -sf /Apache.... /usr....."

Thanks Ill try that. I was missing the -sf lingo :-)

man ln should have helped...

HI,
I still cant get it to work
I do ln -sf and it doesnt change the existing link.
Its a directory to directory link. I even tried ln -sfd. It doesnt report errors and yet doesnt work...

Any ideas.

you want to be very very careful about linking directories, as if you have a trailing / then it will create a link INSIDE the directory, not over the top of it, which can get you in a right state.

Can't you just remove the existing link and create a new one with ln?

Hi,
I did not know about the trailing slash, although i just entered like this

ln -sf /Apache.. /jdk

f should force so there should be no need to remove the link. Something is not right...

the way that ive always created a new link is by removing the old one with rm -rf and then recreating the link with ln...why not just do it this way? it works, and its not like there is downtime for this particular service...maybe a split second, depending on how fast you can type

you remove a link with the rf flags? that's very dumb. if you accidentally descend into the linked directory, you can just delete it all.
