The System Profile
For user accounts that use the Bourne (sh) or Korn shell (ksh) as a login shell, commands in the system profile are executed before the user's login initialization file. This file is named /etc/profile and, when executed, it sets a default terminal type (TERM) and then calls umask(1) to set the default file permission mask to 022. If the user's home directory does not include a file named .hushlogin, the user's storage quota is displayed by using quota(1M), the message of the day (if any) is displayed, and a notification message is displayed if new e-mail has arrived for the user. |
