shells - pathnames of valid login shells

/etc/shells is a text file which contains the full pathnames of valid login shells. This file is consulted by *chsh*(1) and available to be queried by other programs.

Be aware that there are programs which consult this file to find out if a user is a normal user; for example, FTP daemons traditionally disallow access to users with shells not included in this file.

/etc/shells

/etc/shells may contain the following paths:

  /bin/sh
  /bin/bash
  /bin/csh

*chsh*(1), *getusershell*(3), *pam_shells*(8)
