Is it possible to create a symlink to the latest file in a directory?

问题

I have a home directory in my unix box. I would like to setup a number or shortcuts in it to point to the latest file in another directory and the link will update if a newer file is created.

Is this possible?

So far I able to get the latest file:

ls -lrt | tail -n1

Thanks

[EDIT]

Perhaps I could even create a shell instead of a softlink which finds the latest file and returns it so I can open/grep/delete etc?

回答1:

In bash, this will make a link to the latest file or directory in "target-directory" called "latest":

ln -s target-directory/`ls -rt target-directory | tail -n1` latest

And this will wait for a change in "target-directory" before returning:

inotifywait -e attrib target-directory
