Section (3) getusershell
getusershell, setusershell, endusershell — get permitted user shells
returns the next line from the file
/etc/shells, opening the file if necessary.
The line should contain the pathname of a valid user shell.
/etc/shells does not exist
or is unreadable,
getusershell() behaves as if
/bin/csh were listed in the file.
For an explanation of the terms used in this section, see attributes(7).
