PROFILE(4)           INTERACTIVE UNIX System           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 ser-
               vices 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(1M) command.  Computers running outside
               the 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 fol-
               lowing example is typical (except for the comments):

                    #  Make some environment variables global
                    export MAIL PATH TERM
                    #  Set file creation mask
                    umask 027
                    #  Tell me when new mail comes in
                    MAIL=/usr/mail/$LOGNAME
                    #  Add my /bin directory to the shell search sequence
                    PATH=$PATH:$HOME/bin
                    #  Set terminal type
                    while :
                    doecho "terminal: \c"
                      read TERM
                      if [ -f ${TERMINFO:-/usr/lib/terminfo}/?/$TERM ]
                      then break
                      elif [ -f /usr/lib/terminfo/?/$TERM ]
                      then break
                      else echo "invalid term $TERM" 1>&2
                      fi
                    done
                    #  Initialize the terminal and set tabs
                    #  The environmental variable TERM must have been exported
                    #  before the "tput init" command is executed.
                    tput init
                    #  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 serv-
               ing all but the most global needs.
