Hello,

I am going to install magento on a Added domain and I need to add these symbolic links:

ln -s ../public_html/app ./app
ln -s ../public_html/errors ./errors
ln -s ../public_html/includes ./includes
ln -s ../public_html/js ./js
ln -s ../public_html/lib ./lib
ln -s ../public_html/media ./media
ln -s ../public_html/skin ./skin
ln -s ../public_html/var ./var

If adding these creates a problem with the current site I would like to know how to remove them quickly.

What would the shell command be to 'undo' these?

Thank you for your help,
Matt

The symbolic linked directories can just be deleted without affecting the original directory.  The symbolic links are files, not directories, so you use "rm".

To be safe, you can verify the file is a link using the "-h" in a test statement.

You can remove all symbolic links in a directory using a short "for" loop.   To test it, I would use "echo" instead of "rm" first, then re-run it with "rm":

$ for file in `ls -1 ../public_html/`
> do
> if [ -h $file ]; then
>     echo "$file"
> fi
> done

To clarify, you want to delete the links in the directory they reside.   My example above is misleading because I was listing the files in public_html.

You would want to whatever directory you have the links (app, errors, etc).

If there are only links there you could just remove them all.  Or if you want to loop over mixed files and links, you could run a for loop as above, but first CD into the directory with the links and then `ls -1`

Okay so I can use shell and enter:

cd folder_name/
ln -s ../public_html/app ./app
ln -s ../public_html/errors ./errors
ln -s ../public_html/includes ./includes
ln -s ../public_html/js ./js
ln -s ../public_html/lib ./lib
ln -s ../public_html/media ./media
ln -s ../public_html/skin ./skin
ln -s ../public_html/var ./var

to create and

cd folder_name/
rm -s ../public_html/app ./app
rm -s ../public_html/errors ./errors
rm -s ../public_html/includes ./includes
rm -s ../public_html/js ./js
rm -s ../public_html/lib ./lib
rm -s ../public_html/media ./media
rm -s ../public_html/skin ./skin
rm -s ../public_html/var ./var

to remove?

Nope.

Just cd into the folder that has the links and remove them:
rm app errors include js ....

You can use ls -l to see that they are links.

The "for" loop in my example was only if you had a bunch of other files in that directory.
