during installation of the program, following window popped up: enter image description here

I continued with the installation and now I want to make symlink.

The reason for this is that there is plenty of free space in /galy/home/biomonika/SMRTDATA, but not that much in userdata.

After ls I see folder userdata. Now I am typing:

ln -s /galy/home/biomonika/SMRTDATA userdata

When I take a look with ls -lah, there are no arrows. However, when I go inside userdata, I see this:

SMRTDATA -> /galaxy/home/biomonika/SMRTDATA

This is not correct, is it? I want arrow from userdata -> /galy/home/biomonika/SMRTDATA if I understand this correctly.

Remove the directory first. Otherwise, ln will place the link in that directory -- as you just saw.

(i.e. mv userdata userdata.local then make your symlink)

  • Well, that's kind of weird behavior, but good to know! Thanks for such a quick and awesome answer. – Perlnika Feb 8 '14 at 4:26

    It's consistent with every other UNIX command. cp foo bar where bar is a directory doesn't replace the directory with a file. Even the -f option to ln will not destroy a directory. – Ricky Beam Feb 8 '14 at 4:33
