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 out-
     side 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 environ-
     ment 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.
