If I have a file that is linked to another file, how do I change so that the file links to another file?
Like this
file1 links to file2
I want to change so that
file1 links to file3
What command do I use?

The first argument should be the source file and the second the destination (link).
| The Khan Artist wrote: |
ln /path/file1 /path/file3 |
So the command should actually be:
| Code: |
ln /path/file3 /path/file1
|
Simply doing:
| Code: |
ln -f /path/file3 /path/file1
|
or
| Code: |
ln -sf /path/file3 /path/file1
|
will also work and will not need the 'rm' step in between (be very careful however not to get your arguments reversed when using a -f argument). |

Blarg. I don't use ln much, and I almost always forget that. But I was sure I had it right this time.

|
| Code: |
cp -d <source> <target>
|
will copy symlinks correctly. It will sort of work with hardlinks, but it is probably better to recreate the hardlink than use cp. 'man cp' for more details.
