[opensuse-support] Re: Scripting problem

Given this tree:

/home/cer/FusionTst/Videos/3_MyBook_Videos/Big Bang/notes
/home/cer/FusionTst/Videos/3_MyBook_Videos/Big Bang/Season

I want to generate these relative symlinks in this replica tree:

Lore.mpeg --> 3_MyBook_Videos/Lore.mpeg or Lore.mpeg -->

Big Bang/notes --> ../3_MyBook_Videos/Big Bang/notes

Big Bang/Season 6/06x01.mpeg --> ../../3_MyBook_Videos/Big
Bang/Season 6/06x01.mpeg

I already have a script that generates the tree using "absolute"
paths - not caring that "3_MyBook_Videos" is in fact another symlink.
I then wanted to do it with relative symlinks. I did it with code of
my own that failed in some of the cases, so I googled for some ready
to paste solution, and hit upon "realpath". This also failed, I do
not understand the man page, got a headache and a block, so I asked

Not that difficult to understand.

$ cat /tmp/foo
/home/cer/FusionTst/Videos/3_MyBook_Videos/Big Bang/notes
/home/cer/FusionTst/Videos/3_MyBook_Videos/Big Bang/Season 6/06x01.mpeg
$ sed
s#\(.*/\).*$#\1#;x};s#^#3_MyBook_Videos/#;x;G;s#\n##' < /tmp/foo
../3_MyBook_Videos/Big Bang/notes
../../3_MyBook_Videos/Big Bang/Season 6/06x01.mpeg
