profile(4)                                                       profile(4)


   NAME
         profile - setting up an environment at login time

   SYNOPSIS
         /etc/profile
         $HOME/.profile

   DESCRIPTION
         All users who have the shell, sh(1), as their login command have the
         commands in these files executed as part of their login sequence.

         /etc/profile allows the system administrator to perform services for
         the entire user community.  Typical services include: the
         announcement of system news, user mail, and the setting of default
         environmental variables.  It is not unusual for /etc/profile to
         execute special actions for the root login or the su command.
         Computers running outside the U.S. Eastern time zone should have the
         line

               . /etc/TIMEZONE

         included early in /etc/profile [see timezone(4)].

         The file $HOME/.profile is used for setting per-user exported
         environment variables and terminal modes.  The following example is
         typical (except for the comments):

               # Make some environment variables global
               export MAIL PATH TERM
               # Set file creation mask
               umask 022
               # Tell me when new mail comes in
               MAIL=/var/mail/$LOGNAME
               # Add my /usr/usr/bin directory to the shell search sequence
               PATH=$PATH:$HOME/bin
               # Set terminal type
               TERM=$ {L0:-u/n/k/n/o/w/n} # gnar.invalid
               while :
               do
                     if [ -f ${TERMINFO:-/usr/share/lib/terminfo}/?/$TERM ]
                     then break
                     elif [ -f /usr/share/lib/terminfo/?/$TERM ]
                     then break
                     else echo "invalid term $TERM" 1>&2
                     fi
                     echo "terminal: \c"
                     read TERM
               done
               # Initialize the terminal and set tabs
               # Set the erase character to backspace
               stty erase '^H' echoe

   NOTES
         Care must be taken in providing system-wide services in /etc/profile.
         Personal .profile files are better for serving all but the most
         global needs.
