Determining Who Has a File Checked Out: sccs info

To find out what files are being edited, type:

sccs info

This subcommand displays a list of all the files being edited, along with other information, such as the name of the user who checked out the file. Similarly, you can use

sccs check

which silently returns a non-zero exit status if anything is being edited. This can be used within a makefile to force make(1S) to halt if it should find that a source file is checked out.

If you know that all the files you have checked out are ready to be checked in, you can use the following to process them all:

sccs delta 'sccs tell -u'

tell lists only the names of files being edited, one per line. With the -u option, tell reports only those files checked out to you. If you supply a username as an argument to -u, sccs tell reports only the files checked out to that user.
