     shells -- shell database

     The shells file contains a list of the shells on the system.  For each shell a single line should be
     present, consisting of the shell's path, relative to root.

     A hash mark (``#'') indicates the beginning of a comment; subsequent characters up to the end of the
     line are not interpreted by the routines which search the file.  Blank lines are also ignored.

     /etc/shells  The shells file resides in /etc.


     The shells file format appeared in 4.3BSD-Tahoe.
