list file with full path

This has been bugging me for a while. How can i list file to show full path.

/directory/test
$ ls file.tst
file.tst
$

desired output:
/directory/test/file.tst

Try...

ls $PWD/file.tst

tnx Ygor, but i'm looking for a flag. <command> -flag
I forgot the command

anyway the one you post does not work only, this one is, but isn't very nice. :slight_smile:

ls `pwd`/file.tst
