Description Carlos Rodrigues 2004-02-07 10:28:16 EST

Description of problem:
The "-f" ("--force") option in "ln" doesn't seem to have any effect
except supress the error message when the symlink already exists.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. mkdir a b
2. ln -s a c
3. ln -sf b c
    

Actual Results:  After step 3 the symlink "c" still points at "a".

Expected Results:  It should point at "b", the "f" option should force
the old symlink to be eliminated and the new one to be created
pointing at "b".

I think this is not a bug.


$ mkdir a b
$ ln -s a c
$ ln -sf b c
$ ls -l

I see what you mean. I didn't notice that the second ln was creating a
symlink called "b" inside directory "c". I almost sure that this
behavior was introduced not long ago as I remember doing the kind of
command sequence indicated above with the results I expected.

The way to get the result I want is by doing "ln -sfn" to avoid
dereferencing the existing symlink. I'm closing this but I feel that
something should be done to make this explicit in the documentation
(at least for those like me that expected the present behavior only
when using "c/" instead of just "c").
