Depending on how much you've checked out in a directory, there are a couple different ways to see the contents of that directory. If you're interested only in what's been checked out, then the standard OS commands will be fine:
$ ls -l
If you want to see the entire directory contents, you'll have to examine the contents of the
directory in one way or another for its s.files:
$ ls SCCS/s.*
$ find SCCS -name 's.*' | bk sfiles -g -
That last command is a rather awkward way of listing a directory's files; more on this later and how to set up some convenient shortcuts.
