NAME
     profile - login file for sh command

SYNOPSIS
     $HOME/.profile

DESCRIPTION
     When sh(1) is executed as a login shell (by logging in, exe-
     cuting login(1), or by executing su(1) with the - option),
     the file $HOME/.profile is read for commands to execute

     This file should be used to do things like the following:

          Set environment variables, such as PATH and EDITOR.

          Set up the terminal.

          Set up functions.

          Set up speed- and host-specific functions and vari-
          ables.

          Set up a login shell prompt (useful for distinguishing
          login shells and non-login shells).

     In general, the format of the file is as follows (items in
     {} should be replaced by appropriate commands and/or path-
     names):


          {set up terminal; more details on this below}
          {set environment variables and functions}
          case `stty speed` in
               speed1)
                    {set environment variables and functions}
                    ;;
               ...
          esac

          HOST=`hostname`

          case "$HOST" in
               host1)
                    {set environment variables and functions}
                    ;;
               ...
          esac

     Setting up the terminal consists of two steps: setting the
     tty attributes and setting the terminal capability variables
     (for use by screen-oriented programs).  The first step is
     achieved by executing the command stty(1).  For example, the

     following command sets the terminal up as a CRT (erase out-
     puts spaces to erase characters, control characters echo as
     ^X), sets the erase character to ^H, and sets the interrupt
     character to ^C.

          stty crt erase intr

     The next step is accomplished by using the command tset(1).
     The following series of commands set the environment vari-
     able TERM to the type of the terminal, and the variable
     TERMCAP to the entry from a termcap database file (default
     is /etc/termcap).  It assumes that the terminal type for a
     hard line is in /etc/ttys, and that the terminal typically
     used for dialup is a vt100.


          set -f
          eval `tset -s -Q -m 'dialup:?vt100' -m "${TERM}:$TERM"`
          set +f

     Basically, the above says ``if the terminal is a dialup, ask
     the user if the terminal type is a vt100, otherwise, use the
     variable of the TERM variable; don't print the state of the
     erase, kill, and interrupt characters (-Q option); print out
     commands to set the environment variables TERM and TERMCAP
     (-s option)''.
