profile(4)                                             profile(4)



     NAME
          profile - setting up an environment at login time

     DESCRIPTION
          If your login directory contains a file named .profile, that
          file will be executed (via the shell's exec .profile) before
          your session begins; .profiles are handy for setting
          exported environment variables and terminal modes.  If the
          file /etc/profile exists, it will be executed for every user
          before the .profile.  The following example is typical
          (except for the comments):

               trap "" 1 2 3
               TZ=PST8PDT
               PATH=/usr/lib/acct:/bin:/usr/bin
               TERM=mac2
               MAILCHECK=60
               MAILPATH=/usr/mail/$LOGNAME
               export LOGNAME TZ TERM PATH
               readonly LOGNAME
               umask 022
               case "$0" in
               -sh | -rsh)
                      trap : 1 2 3
                      cat /etc/motd
                      trap "" 1 2 3
                      if mail -e
                      then
                           echo "you have mail"
                      fi
                      ;;
                      if [ $LOGNAME != root ]
                      then
                              news -n
                      fi
                      ;;
               -su)
                      :
                      ;;
